These "Keep It Fresh" worksheets are designed to support box plot (box and whiskers) drawing skills. Assigning an occasional worksheet helps students maintain the concepts.
Each worksheet displays a set of numerical data reflecting some real-world context. The student is asked to summarize the data by calculating the 5-number summary (minimum, Q1, median, Q3, maximum), the IQR, and the range. Then, the students is asked to construct the box plot and characterize the skewness of the distribution. Students may either draw a box plot on the printed axis or paste a plot they have created using technology.
An answer key is included.

NOTE: Q1 and Q3 are computed as the **medians** of the lower half and upper half of the sorted data, respectively. According to the 1.5 * IQR rule, none of the data in the worksheets are outliers.
