Students began their study of measures of central tendency today as we learned how to calculate Mean, Median, Mode and Range for any given set of data. Students took the following definitions down in their math notebook:

We worked several examples together to ensure students understand the procedures for determining each measure. The most important thing to remember is this:

**ORDER THE DATA from least to greatest BEFORE working with the data set!!!!! **

Most all of these calculation will be thrown off from the correct answer if the data isn’t ordered from least to greatest FIRST!!!! Keep that in mind tonight as you work!
