Again lets take the set of scores: 15,20,21,20,36,15,25,15 to compute the standard deviation, we first find the distance between each value and the mean.

Below is a normally distributed bell curve, which typically means that most of our scores should cluster around the center with fewer and fewer scores as you move away from the average. The mean is just the average. Measures of central tendency include the , and , while measures of variability include the or , the minimum and maximum values of the variables, and.

It is the sum of all your measurements, divided by the number of measurements. It is a form of investigation in which the researcher has direct control over independent variable as its expression has already occurred or because they are essentially non-manipulable.
