Problem 11E

The following values are the starting salaries, in $000, for a sample of five accounting graduates who accepted positions in public accounting last year.

36.0 |
26.0 |
33.0 |
28.0 |
31.0 |

a. Determine the mean, median, and the standard deviation.

b. Determine the coefficient of skewness using Pearson’s method.

c. Determine the coefficient of skewness using the software method.

Solution

Step 1 of 3

a) We have to find mean, median and standard deviation for the given data

The given data is 36, 26, 33, 28, 31

Arrange the values in the ascending order 26, 28, 31, 33, 36

Here n=no.of value=5

Mean

= ( 26+28+31+33+36)/5

=30.8

Median

=

=

=31

Standard deviation

=

=

=

=3.96

Hence Mean=30.8

Median=31

standard deviation =3.96
