Textbook Problem

For the following sample:

**a.**Assume that the scores are measurements of a continuous variable and find the median by locating the precise midpoint of the distribution.**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,

- 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**and**Y**-axis**.** - Choose
**Continue**> 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.
