Question: Find the skewness from the following data
| Height (in inches) | Number of persons |
| 58 | 10 |
| 59 | 18 |
| 60 | 30 |
| 61 | 42 |
| 62 | 35 |
| 63 | 28 |
| 64 | 16 |
| 65 | 8 |
Solution:
Height is a continuous variable, and hence 58″ must be treated as
57.5″ – 58.5″, 59″ as 58.5″ —59.5″, and so on.
The two coefficients are differents because of the difficulties associated with determination of mode.
