Answer 1

Directions: Type your response in the box.
Mrs. Tallion has conducted two tests so far this grading period. She recorded the grades in her grade book for each test. Based on the collected data for her first period class, she determined the following.

Test 1st 2nd
Minimum 54 57
Maximum 100 98
Mean 73 76
Median 75 72
Mean Absolute Deviation 9.6 9.2
Interquartile Range 24 28
Part A: If a dot plot is made of the combined data, explain in detail what she should see. (Is there overlap in the data? Can she tell there are two sets being measured or does it look like one set of data? Does this information say anything about which data set has the most variability?)

Part B: If a box-and-whisker plot is made of each data set over the same number line, explain in detail what she should see. (Is there overlap in the data? Is there overlap within the 1st and 3rd quartiles? Does this information say anything about which data set has the most variability?)
