Practice Test 4

The table shows the heights (in cm) of two middle school sports teams. Use the data to compare the two distributions.

1. Find each team’s mean.

2. Use the MAD values given to decide whether the distributions have high overlap or noticeable separation.

Which statement is correct?

Two teams recorded heights (in cm) of 8 students each.

Basketball team: 176, 178, 179, 180, 181, 182, 183, 185

Soccer team: 166, 168, 169, 170, 171, 172, 173, 175

The mean height for basketball is 180 cm with MAD = 3 cm. The mean height for soccer is 170 cm with MAD = 3 cm.

Which statement best describes the overlap and how far apart the centers are compared to the variability?
