Lesson Summary:

In this lesson, you will learn how to find the mean, mode, and median from a frequency table for both discrete and grouped data. To find the mean, you multiply the midpoints by frequencies and divide by the total of the frequencies. The mode is the most common value in the data set, and the median is the value of the middle data point when you put the data in order of size. By working through a variety of practice problems, you'll be able to solidify your understanding of these important concepts.
