This document provides calculations and solutions for finding the mean, median, and mode of sample data. It contains a frequency table with data on student heights in meters. It then shows the calculations and solutions for: 1) Finding the sample mean of 1.78 meters by summing the products of each height and frequency and dividing by the total sample size. 2) Finding the median of 1.781 meters using the definition of median and the cumulative frequency table. 3) Discussing two cases for calculating the mode, which has the highest frequency of 30 in the third interval.
