The data given was scattered and therefore not decipherable.
To determine the median test score from a stem-and-leaf plot, we follow the procedures below:
• First, list the test scores from the least to greatest.
,• Next, find the middle test score by following the rule as applicable below.
Case 1
If the total number of test scores is odd, there will be only one middle score and that will be the median test score.
Case 2
If the total number of test scores is even, there will be two middle scores and we calculate the mean of the middle scores to find the median test score.
