6th grade mean, median, mode and range

Quick answer

In 6th grade (ages 11–12), students learn what makes a question statistical, find the mean, median, mode and range, and read dot plots, histograms and box plots. This playlist starts with Khan Academy and Math Antics, then adds Math with Mr. J. Repeat one worked example with an A–B loop until it sticks.

What should a 6th grader be able to do after this unit?

Tell a statistical question from a non-statistical one, find the mean, median, mode and range of a data set, describe spread with the interquartile range or mean absolute deviation, and read dot plots, histograms and box plots. Grade levels vary by country and school.

How does RepeatWatch help with statistics practice?

Loop the part where the teacher orders the data and finds the middle value, and slow it to 0.75× to follow the adding and dividing for the mean. Save each measure on keys 1–9, and use Stop after N loops to keep sessions short.

Frequently asked questions

What is the difference between mean and median?

The mean adds all the values and divides by how many there are. The median is the middle value once the data is in order. The Khan Academy videos near the end show how one very high or low value changes the mean more than the median.

What are MAD and IQR?

Both describe how spread out data is. Mean absolute deviation is the average distance from the mean, and the interquartile range is the spread of the middle half of the data. Khan Academy covers each with worked examples.
