Textbook Problem

For the following sample:

  1. a. Assume that the scores are measurements of a continuous variable and find the median by locating the precise midpoint of the distribution.
  2. b. Assume that the scores are measurements of a discrete variable and find the median.

Scores: 1    2    3    3    3    4

a.

To determine

To find: The medianassuming scores are measurements of a continuous variable.

Explanation

Given info:

The samples of scores are: 1, 2, 3, 3, 3 and 4.

Calculations

Since this is for a continuous variable,let’s draw the histogram.

Software procedure:

Step-by-step procedure to obtain the sum of scores, X using the SPSS software:

  • Go to Variable View> Enter the name of the variable as X.
  • Go to Data View>Enter the values of X and frequency
  • Choose Chart builder>Histogram> choose Simple.
  • Select X andY-axis.
  • ChooseContinue> choose OK.

Output using the SPSS software is given below:

b.

To determine

To Find: The median assuming scores are measurements of a discrete variable.
