Mean vs Median Test Score Analysis

A researcher is analyzing the test scores of a class of 10 students who participated in a mathematics exam. The raw score data collected is as follows:

45, 67, 89, 90, 56, 78, 90, 65, 72, 82.

From this data, the researcher wants to calculate the following:

1. The mean score
2. The median score
3. The mode score

Based on these calculations, determine the relationship between the mean and the median score.
