Question

For a skewed distribution, median is 30 and mode is 35 what is the value of mean?

Answer 1

A skewed distribution follows this relation between its mean, median and mode:

Mode = (3 × Median) - (2 × Mean)

According to the question, we have:

• median = 30
• mode = 35

We need to find the mean.

Let's substitute the values we have into the formula and find the value of the mean.

35 = (3 × 30) - (2 × Mean)

35 = 90 - (2 × Mean)

-55 = - (2 × Mean)

-55/-2 = Mean

27.5 = Mean

Therefore, the mean is 27.5.
