Free Printable Data Comparison Worksheets for Class 7

Start with two data sets drawn from a familiar context, such as daily temperatures in two cities. Have students compare the centers, spreads, and shapes of the distributions before deciding which group is typically higher and which is more variable. Require each conclusion to cite evidence from the graph or statistical summary.

Useful exercises include matching box plots to statistical summaries, comparing medians and ranges across two distributions, and writing a claim supported by a graph. Problems that ask which measure best supports a conclusion help students move beyond calculation to interpretation.

Students often compare only the highest values, confuse range with a typical value, or treat a small difference in medians as meaningful without considering variability. They may also describe each graph separately instead of making a direct comparison. Sentence frames such as “Data set A has a higher median, while Data set B has a wider spread” can correct that habit.

Common Core expects Grade 7 students to use measures of center and variability, along with visual overlap, to compare two populations. This builds on describing single distributions and prepares students to analyze relationships and more complex statistical displays in later grades.

Give students who struggle with dense displays a worksheet version with larger text or wider spacing, then use reduced answer choices in the digital activity to focus attention on the strongest comparison. Advanced students can justify which statistic best supports a conclusion rather than simply calculating it.

Students begin comparing simple data displays in earlier grades, but Grade 7 typically introduces formal comparisons between populations using measures of center and variability. At this level, students are expected to support conclusions with numerical and graphical evidence.
