Answer:
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
