Calculate Karl – Pearson’* coefficient of skewness from the following data.

Question 1

| Year | 0-10 | 10-20 | 20-30 | 30-40 | 40-50 | 50-60 | 60-70 | 70-80 |
| No. of persons | 10 | 40 | 20 | 0 | 10 | 40 | 16 | 14 |

Question 2

The frequency distribution is *-modal, so using Karl-Pearson’ coefficient of skewness for ill-defined data:

= 3(X -m)/σ

Let C.I and f be the Age and no.of persons

The distribution is negatively skewed.
