1 |
Problem |
Calculate the given data by using coefficient of skewness.1, 2, 3, 4, 5, 6, 7, 8, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 9, 10, 12, 12, 13. The given standard deviation is 2.98 |

3 |
Hint |
Mean = \$" Sum of the observations "/" total number of observations" \$ |
|
4 |
Step |
sum of observations = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 10 + 12 + 12 + 13 |
|
5 |
Step |
Number of observations |
24 |
6 |
Clue |
Mean |
\$194 / 24 = 7.96\$ |
7 |
Clue |
Standard deviation |
2.98 |
8 |
Step |
Skewness |
sk = \$(Mean - Mode) / (sd)\$ |
9 |
Step |
Simplification |
\$(7.96 - 9) / 2.98\$ |
10 |
Step |
After simplification we get |
- 0.34 |
