Find Karl Pearson’* coefficient of skewness for the following data.
| CI | 10-14 | 15-19 | 20-24 | 25-29 | 30-34 | | f | 5 | 9 | 15 | 13 | 8 |
X = Midpoints or C.l.
Modal class = size of highest frequency
Modal class = 20-24
After converting into exclusive CI = 19.5 – 24.5
The distribution is negatively skewed
