Textbook Problem

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

  1. a. Sketch a histogram showing the sample distribution.
  2. 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).
  3. 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:

XFrequency
21
31
52
62
81

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.
