A psychologist investigated academic anxiety in two groups of students. Students in Group X studied fully online, and students in Group Y attended traditional in-person classes. Each student completed a standardised anxiety scale and was given an overall score (where higher scores indicate higher anxiety). The psychologist then calculated average scores for each group. The results are shown in Table 3 below.
| Measure of central tendency | Group X scores | Group Y scores |
|---|---|---|
| Mean | 45.3 | 38.5 |
| Median | 45.0 | 44.0 |
| Mode | 45.0 | 48.0 |
Using the data in Table 3, explain how the distribution of scores in Group X differs from the distribution of scores in Group Y.
