Mode Calculation Using Empirical Relationship
For a moderately skewed distribution, the relationship between the mean, median, and mode can be approximated by the empirical formula:
$Mode = 3 \times Median - 2 \times Mean$
Given Values:
- Mean = 78
- Median = 61
Applying the Formula:
- Substitute the given Mean and Median into the formula:
$Mode = 3 \times 61 - 2 \times 78$
- Calculate the terms:
$Mode = 183 - 156$
- Compute the final value:
$Mode = 27$
Therefore, the mode of the distribution is 27.
