Data Set: 13, 1, 18, 20, 18
• Mean =
Median =
• Mode =
• Range -
• Outlier -

mean=14

median=3

mode=20

range=19

mean=14

median=18

range=19

outlier=1

mode: 18

Step-by-step explanation:

1) to find the mean, add up all the numbers and divide by number of numbers:

13+1+18+20+18=70

70/5=14

mean=14

median: to find median arrange all numbers from least to greatest and cross of each one, alternating between sides until you get to one last number:

(an underline means crossed out)

1,13,18,18,20

median=18

mode is the most recurring number, in this data set the mode is 18

range(largest number-smallest number)

range:(20-1)

range: 19

outlier: (number tat doesnt belong)

outlier: 1
