Sophia: Finding the Mean of a Set of Data

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

This video lesson demonstrates how to calculate the mean for a set of data. Students can check their understanding with an assessment.

There are eight decimals numbers in this data set. Find the mean. So add all the terms together and then divide that total number by the number of terms in the data set. That's how you find the mean or average of a data set.

This video lesson demonstrates how to find the mean of a data set. It includes detailed examples about when it is appropriate to find the mean.

Represent data graphically. Allow your class to explore different methods of representing data. They create foldables, sing songs, and play a dice game to reinforce the measures of central tendency.

This lesson demonstrates how to find the mean of a set of data. It is 1 of 6 in the series titled "Finding the Mean of a Set of Data."
