Chapter 8, Problem 1VC

To determine

To fill in the blanks "Another word for average is ______."

Answer to Problem 1VC

Mean

Explanation of Solution

Given information:

Sample Standard Deviation	0	Dispersion	X
Range	1	Grade Point Average	Mode
Sample Standard Deviation	Population Standard deviation	Mean	Median
Normal Distribution Curve	$\sqrt{\frac{\sum {(x-\overline{x})}^2}{n-1}}$	$\sqrt{\frac{\sum {(x-\overline{x})}^2}{n}}$	$\overline{x}$
Sample	Population	Empirical

The word for Average is mean. We calculate mean and Average by summing up all the observation in a sample and then divide the sum by no. of observation in sample. Mean is denoted by $\overline{x}$

Formula for Mean and Average:

  $\overline{x}=\frac{\sum x_i}{n}$

Conclusion:

Another word for average is mean.
