Question

Given the following data, calculate the mean , median , mode and range

Answer 1

mean - 294.1
to find the mean all you have to do is add all numbers and divide it by how many numbers there are so in this problem you add all of them and divide by 20
median - 15
to get this number you have to put the numbers in order and then find the middle number
mode - 15
most common number
range - 11
subtract the largest and smallest numbers 22-11=11

Hope this helps

Answer 2

To find the mean, you will have to order the numbers from least to greatest, then add the number together which in this case equals 232 then divide by the number data points there are which equals 13.65


To fiind the median you just keep crossing out number from each side until you are left with one number and in this case the median would be 15.


The range you just subtract the largest number (21) from the lowest number (11) which equals 10.


The mode is the value that occurs the most often in this case it would be would be 15
