Textbook Problem

For the following sample of *n* = 7 scores: 8 6 5 2 6 3 5

- a. Sketch a histogram showing the sample distribution.
- b. Locate the value of the sample mean in your sketch, and make an estimate of the standard deviation (as done in Example 4.5).
- c. Compute
*SS*, variance, and standard deviation for the sample. (How well does your estimate compare with the actual value of .*s*?)

**(a)**

To determine

**To Sketch:** The histogram for the population distribution.

Explanation

**Given info:** The population scores are 8, 6, 5, 2, 6, 3 and 5

**Calculation:**

Create a frequency distribution table as:

X | Frequency |

2 | 1 |

3 | 1 |

5 | 2 |

6 | 2 |

8 | 1 |

**Software procedure:**

Step-by-step procedure to obtain the frequency distribution table using the SPSS software:

- Enter the data under Scores column.
- Go to
**Graphs >**select**Chart builder...**

**(b)**

To determine

**To find:** The mean in the histogram.

**(c)**

To determine

**To Find:** The sum of squared deviations, variance and standard deviation for the population of scores.
