C
Explanation :
The most frequently used measure of variability in a research study is the standard deviation, which describes how spread out the data is from the mean. Central tendency refers to measures such as the mean, median, and mode that represent the typical or central value of a dataset. Variance is another measure of variability, but it is less commonly used than standard deviation in research studies.
