Task Description

Prompt Features: The student is prompted to informally assess the degree of visual overlap of two numerical data distributions. Stimulus Guidelines: Context must be familiar to students 12–14 years old. Visual displays should be dot plots, histograms,...

Stimulus

The student is presented with two numerical data distributions with similar variability.

Example 1

Example Stem: The box plot shows a summary of test scores for Class A and Class B on the same exam. Both classes have the same number of students.

Two box plots are shown along a number line labeled Test Scores ranging from 66 to 98. Class A: the whiskers range from 68 to 95. the box ranges from 78 to 92. The median is 85. Class B: the whiskers range from 71 to 96. The box ranges from 79 to 93. The median is 90.

Determine whether each statement is true based on these box plots. Select True or False for each statement.

Statement True False
In each class, at least 25% of students scored below 80 on the test.
The median test score of Class B is 5 points less than the median test score of Class A.
In each class, more than 25% of students have test scores greater than 90.

Rubric: (1 point) Student correctly identifies each statement as true or false (e.g., T, F, T). False statements could include incorrect interpretations of the measures of variability.
