Inferential Statistics. Inferential statistics is concerned with making predictions or inferences about a population from observations and analyses of a sample. That is, we can take the results of an analysis using a sample and can generalize it to the larger population that the sample represents.
Statistics are divided into two general categoriesâdescriptive 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.
