Mean mode median range 6 9 19 12 7 10 18

Hey!

Mean is the average. To calculate mean, add all the numbers and divide by how many numbers there are.

There are 7 numbers.

The mean is 11.6(rounded)

Mode is the number that appears the most often. In this data set, all the numbers appear once. That means there is no mode.

No mode

Median is calculated by ordering the numbers from least to greatest and finding the middle number.

The median is 10

Range is the difference between the greatest and least number.

Subtract

The range is 13

Hope this helps! :)

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

answer: .64
