Not all data is the same. Using the interactive, pupils compare data represented in two different ways. The learners develop an understanding of the difference between discrete and continuous data and the different ways to represent each...

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.

Join Zoe as she calculates the average number of points RJ scored in his basketball games. This step-by-step presentation clearly models the procedure for finding the mean of a data set, including examples with both whole number and...

Mean, mode, median? What's the difference? How do you find them? The teacher focuses on explaining median in this video. She gives a good explanation and shows how to order a data set to find the median number. This given data set has an...
