Mean
What is the formula of mean?
Sum of terms/
Number of terms
What do you do if their is not one middle number?
You find the middle of those numbers to decide the median.
What does mode mean?
The value(number) that is repeated more than once
What does range mean?
Range is the difference between highest and lowest value
What is the mean of absolute deviation in statistics?
The mean absolute deviation of a data set is the average of the absolute deviations from a central point.
