Calculate the mean and median for the grouped data and Graph the data using a histogram. Mark the measures of central tendency.

Definition Definition Characteristic of data to concentrate at certain values, usually in the center of the distirbution. The central tendency of the data is measured by descriptive statistics like mean, median, and mode, which are known as measures of central tendency. Depending upon the type of data under study, some measures of central tendency become more appropriate to use than others.
