Student Statement
I am able to accurately calculate the range and interquartile range of any given set of data.
I am also able to decide which measure of spread would be better to use to describe a given set of data.
Common Core Standards
ID.A.2: Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.
ID.A.3: Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
Below you will find an option to use a randomized data set or a randomized frequency table. Use it to find the measures of spread (range and interquartile range). Reveal the answers with the "Check Answers" button. Round all numbers to the nearest thousandth when working through the problem.
