- 1. GreenHearts
- 2. At the end of the module, the students will be able to know the following: The computation and interpretation for measures of Central Tendency Computation and interpreattaions for measures of Variability
- 3. MEASURES OF CENTRAL TENDENCY Mean- the most common measure of center and is alsoknown as the “ arithmetic average ”.
- 4. MEASURES OF CENTRAL TENDENCY Median – it is the point Mode – refers to the that divides the scores in scores that occurred a distribution in two most in the distribution. equal parts
- 5. Measures of Variability This is used to describe the spread out of the scores in a distribution that is above or below the measures of central tendency. There are three commonly measures of variability: The range The quartile deviation And the standard deviation
- 6. Three commonly measures of variability: Range – the difference between the highest score and lowest score in the data set. Quartile Deviation – The half of the difference between the third quartile and the first quartile. Standard Deviation – the most important and useful measure of variation, it is the square root of the variance.
