                                                   2. Variables
                                                   A variable is anything that can take on differing or varying values.

                                                         2.1 Types of Variables
                                                   Four main types of variables are discussed in this chapter:

                                                   a.   The dependent variable (also known as the criterion variable).
                                                   b.   The independent variable (also known as the predictor variable).
                                                   c.   The moderating variable.
                                                   d.   The intervening variable.

                                                   Variables can be discrete (e.g., male/female) or continuous (e.g., the age of an

The null hypothesis for the relationship between the two variables in Example
5.17 would be                                                                         The alternate hypotheses for the above null, which has been expressed
                                                                                      directionally in Example 5.17, can be statistically expressed as
HO: There is no relationship between stress experienced on the job and the job                                                      HA: < 0 (The correlation is
    satisfaction of employees.                                                        negative.)

This would be statistically expressed by                                              For Example 5.19, which has been stated nondirectionally, while the null

where represents the correlation between stress and job satisfaction, which in
this case is equal to 0 (i.e., no correlation).                                       The alternate hypothesis would be expressed as:
                                                                                                                                 H0: 0

4.5 Steps in Hypothesis Testing

1. State the null and the alternate hypotheses.
2. Choose the appropriate statistical test depending on whether the data
   collected are parametric or nonparametric (discussed in a later chapter).
3. Determine the level of significance desired (p= 05, or more, or less).
4. See if the output results from computer analysis indicate that the
   significance level is met. If, as in the case of Pearson correlation analysis in
   Excel software, the significance level is not indicated in the printout, look up
   the critical values that define the regions of acceptance on the appropriate
   table [(t, F, χ2)—see tables at the end of the book]. This critical value
   demarcates the region of rejection from that of acceptance of the null
   hypothesis.
5. When the resultant value is larger than the critical value, the null hypothesis
   is rejected, and the alternate accepted. If the calculated value is less than
   the critical value, the null is accepted and the alternate rejected.

2.3. Hypotheses Testing
Studies that engage in hypotheses testing usually explain the nature of
certain relationships, or establish the differences among groups or the
independence of two or more factors in a situation. Hypothesis testing is
undertaken to explain the variance in the dependent variable or to predict
organizational outcomes.
 Example 6.5
A marketing manager wants to know if the sales of the company will
increase if he doubles the advertising dollars. Here, the manager would like
to know the nature of the relationship that can be established between
advertising and sales by testing the hypothesis: If advertising is increased,
then sales will also go up.

Example 6.27
A marketing manager is interested in tracing the pattern of sales of a
particular product in four different regions of the country on a quarterly
basis for the next 2 years. Since data are collected several times to answer
the same issue (tracing pattern of sales), the study falls under the
longitudinal category.

Longitudinal Studies take more time and efforts and cost more than cross-
sectional studies. However, well-planned longitudinal studies could, among
other things, help to identify cause-and-effect relationships.

 iv. Elements of Dimension 4
 A measure of how excited people are at seeking challenging jobs can be had
 by asking employees what kinds of jobs they prefer. Employee preferences
 for different types of jobs could then be placed on a continuum ranging
 from those who prefer fairly routine jobs to those who prefer jobs with a
 progressive increase in challenge.
 v. Elements of Dimension 5
  Those who desire feedback would seek it from their superiors, co-workers,
 and sometimes even from their subordinates. Feedback, both positive and
 negative, would indicate to them how much they are achieving and
 accomplishing. Employees can be placed on a continuum ranging from
 those who seek extensive feedback from all sources to those who never seek
 any feedback from anyone at any time.

Table 9.1 Types of Validity

Validity                                      Description
Content validity             Does the measure adequately measure the concept?
Face validity                Do “experts” validate that the instrument measures what its
                              name suggests it measure?
Criterion-related validity   Does the measure differentiate in a manner that helps to
                              predict a criterion variable?
Concurrent validity          Does the measure differentiate in a manner that helps to
                             predict a criterion variable currently?
Predictive validity          Does the measure differentiate individuals in a manner as to
                              help predict a future criterion?
Construct validity           Does the instrument tap the concept as theorized?
Convergent validity          Does the measure have low correlation with a variable
                               That is supposed to be unrelated to this variable?

Example 5.16 If employees are more healthy, then they will take Example 5.17 sick leave less frequently. The greater the stress experienced in the job, the lower the job satisfaction of employees. Example 5.18 Women are more motivated than men. Ch- 5 THE RESEARCH PROCESS: Steps 4 & 5 Ch- 5 THE RESEARCH PROCESS: Steps 4 & 5 4.4 Null and Alternate Hypotheses On the other hand, nondirectional hypotheses are those that do postulate a The null hypotheses is a proposition that states a definitive, exact relationship or difference, but offer no indication of the direction of these relationship between two variables. That is, it states that the population relationships or differences. In other words, though it may be conjectured that correlation between two variables is equal to zero or that the difference in the there would be a significant relationship between two variables, we may not be means of two groups in the population is equal to zero (or some definite able to say whether the relationship would be positive or negative. number). In general, the null statement is expressed as no (significant) relationship between two variables or no (significant) difference between two Example 5.19 groups, as we will see in the various examples in this chapter. The alternate There is a relationship between age and job satisfaction. hypothesis, which is the opposite of the null, is a statement expressing a relationship between two variables or indicating differences between groups.

The alternate hypothesis would be expressed as: H0: 0 Ch- 5 THE RESEARCH PROCESS: Steps 4 & 5 4.5 Steps in Hypothesis Testing 1. State the null and the alternate hypotheses. 2. Choose the appropriate statistical test depending on whether the data collected are parametric or nonparametric (discussed in a later chapter). 3. Determine the level of significance desired (p= 05, or more, or less). 4. See if the output results from computer analysis indicate that the significance level is met. If, as in the case of Pearson correlation analysis in Excel software, the significance level is not indicated in the printout, look up the critical values that define the regions of acceptance on the appropriate table [(t, F, χ2)—see tables at the end of the book]. This critical value demarcates the region of rejection from that of acceptance of the null hypothesis. 5. When the resultant value is larger than the critical value, the null hypothesis is rejected, and the alternate accepted. If the calculated value is less than the critical value, the null is accepted and the alternate rejected.

Descriptive studies thus become essential in many situations. Whereas qualitative data obtained by interviewing individuals may help the understanding of phenomena at the exploratory stages of a study, qualitative data in terms of frequencies, or mean and standard deviations, become necessary for descriptive studies.

Hypotheses Testing Studies that engage in hypotheses testing usually explain the nature of certain relationships, or establish the differences among groups or the independence of two or more factors in a situation. Hypothesis testing is undertaken to explain the variance in the dependent variable or to predict organizational outcomes. Example 6.5 A marketing manager wants to know if the sales of the company will increase if he doubles the advertising dollars. Here, the manager would like to know the nature of the relationship that can be established between advertising and sales by testing the hypothesis: If advertising is increased, then sales will also go up.

Other Scales 2.1 Paired Comparison There are also some advanced scaling methods such as multidimensional The paired comparison scale is used when, among a small number of objects, respondents are asked to choose between two objects at a time. This scaling, where objects, people, or both, are visually scaled, and a conjoint helps to assess preferences. If, for instance, in the previous example, during analysis is performed. This provides a visual image of the relationships in the paired comparisons, respondents consistently show a preference for space among the dimensions of a construct. product one over products two, three, and four, the manager reliably 2. Ranking Scales understands which product line demands his utmost attention. However, as Ranking scales are used to tap preferences between two or among more the number of objects to be compared increases, so does the number of objects or items (ordinal in nature). paired comparisons. Hence paired comparison is a good method if the number of stimuli presented is small.

This is easier for the respondents, assess attitudes towards the current object, event, or situation under study. particularly if the number of choices to be ranked is limited in number. An example of the use of comparative scale follows.

Goodness of Measures It is important to make sure that the instrument that the instrument that we develop to measure a particular concept is instrument that we develop to 4. Reliability measures a particular concept is indeed accurately measuring the variable, The reliability of a measure indicates the extent to which it is without bias and that in fact, we are actually measuring the concept that we set out to (error free) and hence ensures consistent measurement across time and across measure. This ensures that in operationally defining perceptual and the various items in the instrument. In other words, the reliability of a attitudinal variables, we have not overlooked some important dimensions and measure is an indication of the stability and consistency with which the elements or included some irrelevant ones. instrument measures the concept and helps to assess the “goodness” of a 3.1. Item Analysis measure. Item analysis is done to see if the items in the instrument belong there or not. 4.1 Stability of Measures Each item is examined for its ability to discriminate between those subjects The ability of a measure to remain the same over time—despite uncontrollable whose total scores are high, and those will low scores. In item analysis, the testing conditions or the state of the respondents themselves—is indicative of means between the high-score group and the low-score group are tested to its stability and low vulnerability to changes in the situation. This attests to its detect significant differences through the t-values. The items with a high t- “goodness” because the concept is stably measured, no matter when it is done. value (test which is able to identify the highly discriminating items in the Two tests of stability are test-retest reliability and parallel-form reliability. instrument) are then included in the instrument.

Test-retest reliability Chapter 9: Stability Measurement: Scaling, Reliability, Validity Parallel-form reliability Reliability (accuracy in measurement) Interitem consistency reliability Goodness Consistency 4.2 Test-Retest Reliability Split-half reliability of data The reliability coefficient obtained with a repetition of the same measure on a second occasion is called test-retest reliability. That is, when a Validity questionnaire is administered to a set of respondents now, and again to the (are we same respondents, says several weeks to 6 months later, then the correlation measuring the right between the scores obtained at the two different times from one and the thing?) same set of respondents is called the test-retest coefficient. The higher it is, the better the test-retest reliability, and consequently, the stability of the measure across time. Logical validity Criterion-related Congruent validity (content) validity (construct) Face validity Predictive Concurrent Convergent Discriminant Chapter 9: Chapter 9: Measurement: Scaling, Reliability, Validity Measurement: Scaling, Reliability, Validity 4.3 Parallel-Form Reliability a. Interitem Consistency Reliability When responses on two comparable sets of measures tapping the same This is a test of the consistency of respondents’ answers to all the items in a construct are highly correlated, we have parallel-form reliability. Both forms measure. To the degree that items are independent measures of the same have similar items and the same response format, the only changes being the concept, they will be correlated with one another. The most popular test of wordings and the order or sequence of the questions. What we try to interitem consistency reliability is the Cronbach’s coefficient alpha establish here is the error variability resulting from wording and ordering of (Cronbach’s alpha; Cronbach, 1946), which is used for multipoint-scaled the questions. If two such comparable forms are highly correlated the items, and the Kuder-Richardson formulas (Kuder & Richardson, 1937), used for dichotomous items. The higher the coefficients, the better the measures are reasonably reliable. measuring instrument. 4.4 Internal Consistency of Measures b. Split-Half Reliability The internal consistency of measures is indicative of the homogeneity of the Split-half reliability reflects the correlations between two halves of an items in the measure that tap the construct. In other words, the items should instrument. The estimates would vary depending on how the items in the “hang together as a set,” and be capable of independently measuring the measure are split into two halves. Split-half reliabilities could be higher than same concept so that the respondents attach the same overall meaning to Cronbach’s alpha only in the circumstance of there being more than one each of the items. This can be seen by examining if the items and the subsets underlying response dimension tapped by the measure and when certain of items in the measuring instruments are correlated highly. Consistency can other conditions are met as well. Hence, in almost all cases, Cronbach’s alpha be examined through the inter-item consistency reliability and split-half can be considered a perfectly adequate index of the interitem consistency reliability tests. reliability.

Validity Criterion-related validity is established when the measure differentiates Several types of validity tests are used to test the goodness of measures and individuals on a criterion it is expected to predict. This can be done by writers use different terms to denote them. For the sake of clarity, we may establishing con-current validity or predictive validity, as explained below.

The more the scale items measure fit the theories around which the test is designed. This is assessed represent the domain or universe of the concept being measured, the greater through convergent and discriminant validity, which are explained below. the content validity. To put it differently, content validity is a function of how Convergent validity is established when the scores obtained with two different instruments measuring the same concept are highly correlated. well the dimensions and elements of a concept have been delineated. Discriminant Validity is established when, based on theory, two variables are Face validity is considered by some as a basic and a very minimum index of predicted to be uncorrelated, and the scores obtained by measuring them are content validity. Face validity indicates that the items that are intended to indeed empirically found to be so. measure a concept, do on the face of it look like they measure the concept.

Face validity Do “experts” validate that the instrument measures what its name suggests it measure? Criterion-related validity Does the measure differentiate in a manner that helps to predict a criterion variable? Concurrent validity Does the measure differentiate in a manner that helps to predict a criterion variable currently? Predictive validity Does the measure differentiate individuals in a manner as to help predict a future criterion? Construct validity Does the instrument tap the concept as theorized? Convergent validity Does the measure have low correlation with a variable That is supposed to be unrelated to this variable?
