The middle of an ordered list of values. If the list has an odd number of values, it is the middle of the values of a list. If the list has an even number of values, it is the average of the two middle values.

Numerical values used to describe the overall clustering of data in a set, or the overall central value of a set of data.

The value found most often in a set of numbers.

The arithmetic average of a set of numbers. It is a measure of central tendency.

​ ​ ​ : the "average" value for the data.

​ : the value for which half the numbers are larger and half are smaller.

​ : To find, subtract the smallest value from the largest value in a set of data.

​ : The difference of the values of the first and third quartiles.

• Mean

• Median

• Range

• Interquartile Range

The ​ (a)   is the sum of all the numbers, divided by how many numbers were added together. The ​ (b)   is the middle number when the numbers are put in order. The ​ (c)   is the most common number. The ​ (d)   is the difference between the maximum and minimum values.

• mean

• median

• mode

• range

The ​ ​​ (a)   is found by adding all numbers in a set and dividing by how many numbers there are.

The ​ ​ (b)   is found by subtracting the highest and lowest.

The ​ (c)   is the number(s) that occurs the most often.

The ​ (d)   is the middle number.

The (a)   is the average of a data set.

The ​​ (b)   is the middle of a data set.

The​ ​ (c)   is the number that appears most often in a data set.

The​ ​ (d)   is the difference between the biggest and the smallest number in a data set.

The ​ (e)   is the difference between Q3 and Q1 in a data set.
