Mean, Median, and Mode Mean: the average of numbers Median: the middle range of numbers Mode: the number that occurs most often

Range and Standard Deviation Range: the difference between the lowest and the highest values Standard Deviation: a measure on how you spread out the numbers; square root of the variance 13-5 = 8

Box & Whisker Plot Box & Whisker Plot: a graphic way to display the median, quartiles, and extremes of a data set on a number line to show the distribution of the data.

Conclusion???? In Lake Shore High School the most common shoe size 10.5. With a close second at size 7.
