Chapter 12.3, Problem 6STP

The table at the right shows the number of wins a baseball team had in its first five seasons. What is the mean number of wins the team had per season? What is the median number of wins the team had per season?

To determine

Find mean , median of the given data.

Answer to Problem 6STP

Mean = 77

Median = 76

Explanation of Solution

Given:

68 , 89 , 76 , 59 , 93

Calculation:

Arrange the given data in ascending order :

59 , 68 , 76 , 89 , 93

Mean = $\frac{sum\text{ of all the entries}}{\text{total number of entries}}=\frac{68+89+76+59+93}{5}=\frac{385}{5}=77$

Median = The middle entry is the median.

Since there are 5 entries , the the $\frac{5+1}{2}=3^{rd}$ term is the median after arranging the data in ascending order = 76
