## Statistics practice questions and answers

Measures of central tendency In statistics, the mean, median, and mode are known as measures of central tendency; they are used to identify the center of a data set: Mean: The value between the largest and smallest values of a data set, obtained by a prescribed method. The formulas for the population and sample variance are: Population variance: Sample variance: Percentiles split up a data set into equal parts each consisting of 1 percent of the values in the data set. So, a sample measure, such as the mean, should be a good estimate of the corresponding population measure. Measures of association Another type of measure, known as a measure of association, refers to the relationship between two samples or two populations. The variance and standard deviation are closely related to each other; the standard deviation always equals the square root of the variance. A student from this group is selected randomly.
