Mean: make a "mean" face and put right and left hands next to your face in the shape of claws. The mean is "mean" because we have to do two operations to calculate.Review defintion with gestures two fingers for two operations, crossed arms or fingers for addition; chopping motions for division.

Median: spread right and left arms perpendicular to the floor and bring hands to the middle underneath the chin (as if in prayer or meditation). I use a monotone voice to define - median means middle; put the data in order from least to greatest and find the middle.

Mode: use right or left hand to motion as if scooping ice cream. Mode means the most, so you need at least two scoops.

Range: arms out to the side as in median. Use a slashing motion for subtraction.

Outlier: arms out to the side using a pushing motion to explain that outliers are far from the rest of the data and can be greater than or less than.

blasjo, great idea...definitely on my list next year for mean, median, mode, and range.

Thanks Blasjo,
I'm teaching that topic after the spring break. I'm going to use those gestures. What perfect timing! Thanks!
