Chapter 10, Problem 7SGR

To determine

To explain mean, median mode.

Answer to Problem 7SGR

The answer is as follows

Explanation of Solution

Given information:

Mean, median and mode.

Mean:

Mean is the arithmetic average of the set of values.

Mean, $\overline{x}=\frac{{\displaystyle \sum x}}{n}$

Where ${\displaystyle \sum x}$ is sum of values, n is number of terms.

Median:

Median is the middle value of the set of values when placed sequentially.

Median= ${(\frac{n+1}{2})}^{th}$ observation for n = odd numbers and

Median= $\frac{{(\frac{n}{2})}^{th}ob+{(\frac{n}{2}+1)}^{th}ob}{2}$ for n = even numbers

Mode:

Mode is considered as most repetitive value in the set. If no value is repeated, highest value is considered as mode
