correlation researchs and its techniques
- 2. Introduction: Correlational research involves collecting data to determine whether and to what degree, a relationship exists between two or more quantifiable variables.
- 3. Natural observation 01 Survey research 02 Types of Correlational Research There are three common types of : Archival research 03
- 4. Natural observational is observing and recording variables in a natural environment, without interfering. It can be time consuming and does not allow variable control. Natural Observation
- 5. Survey Research Survey research gathers information via surveys or questionnaires by choosing a random sample of participants. Survey research is quick and convenient, but participants can affect the outcomes in a variety of ways.
- 6. Archival research Archival research analyzes data collected by others. Researchers cannot control the data or how it was gathered.
- 7. Simple and Multiple Correlation: When we check relationship between 2 variables called Simple correlation. When we check relationship between more than 2 variables its called Multi correlation.
- 8. Result of correlation research? Result ranges: +1 to -1 =1_0_+1 Zero correlation: When no relation with variables. No effect on other variable, no matter how much changing occur in other variables.
- 9. Negative correlation Significant changing occurs when one variables change. Inversely proportional to each other. One increase, other decrease. ● Height increase,temperature decrease ● Classes skipped, exam performance low.
- 10. Similar and significant changing occur when one variables change. Increase 1 other also 1, mean directly proportional. ● Like height and weight. ● Weight and wrinkles. ● Grades and self esteem. Positive correlation
- 11. Conducting Correlation Research: ● Select Variables: ● Data Collection: ● Data Analysis: .
