Textbook Problem

For the following population of *N* = 6 scores:

3 1 4 3 3 4

**a.**Sketch a histogram showing the population distribution.**b.**Locate the value of the population mean in your sketch, and make an estimate of the standard deviation (as done in Example 4.2).**c.**Compute*SS*, variance, and standard deviation for the population. (How well does your estimate compare with the actual value of σ?)

**(a)**

To determine

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

Explanation

**Given info:** The population scores are 3, 1, 4, 3, 3, 4

**Calculation:**

Create a frequency distribution table as:

X |
Frequency |

Â Â Â 1 | Â Â Â 1 |

Â Â Â 3 | Â Â Â 3 |

Â Â Â 4 | Â Â Â 2 |

**Software procedure:**

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

- Enter the data under Scores column...

**(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.
