Statistics are divided into two general categoriesâdescriptive and inferential. Descriptive statistics include mean, median, mode, range, sum of squares (sum of squared deviation scores), variance (also known as mean square, which is short for mean of squared deviation scores), and standard deviation. It is assumed that graduate students have some familiarity with each of these statistics.
