Question

A coach had her players take an agility test. Here are their scores: a dot plot has a horizontal axis labeled, score, marked from 0 to 10 in increments of 1. The number of dots above each value is as follows: 1, 1; 5, 1; 7, 1; 8, 2; 9, 3; 10, 3. Find the median score.

Answer 1

The median score of the agility test is 9, which is found by putting the 11 scores in order and identifying the 6th score in the sequence.

Step-by-step explanation:

To find the median score of the agility test, we need to organize the scores in ascending order and locate the middle value. As the dot plot indicates, there are 11 scores in total: 1, 5, 7, 8, 8, 9, 9, 9, 10, 10, 10. The median is the middle score when the scores are lined up in order. With 11 scores, the 6th score is the median. Therefore, the median score is 9, as it is the 6th value in the ordered list.

Students can practice this method by collecting their own data on hours of sleep and using a dot plot to find the median hours slept. Creating a dot plot is an excellent collaborative exercise for understanding how to visualize and analyze data distributions.
