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.

Table 3: Measures of central tendency for Group X and Group Y anxiety scores

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.
