We can use the empirical relationship between the mean, median, and mode: $$ \text{Mode} = 3 \cdot \text{Median} - 2 \cdot \text{Mean} $$
The mode is 24 and the mean is 60.
Let the median be $M$.
Then we have: $$ 24 = 3M - 2(60) $$ $$ 24 = 3M - 120 $$ $$ 24 + 120 = 3M $$ $$ 144 = 3M $$ $$ M = \frac{144}{3} = 48 $$
Therefore, the median of the data is 48.
Find the mean and mode of the following data:
Class | 15--20 | 20--25 | 25--30 | 30--35 | 35--40 | 40--45 |
Frequency | 12 | 10 | 15 | 11 | 7 | 5 |
