Answers
Given : Two Data sets one with outlier , one without outlier
To find : How is the mean affected by an outlier
Step-by-step explanation:
Data without an outlier: 108, 113, 105, 118, 124, 121, 109
Data points = 7
Sum of Data's = 108 + 113 + 105 + 118 + 124 + 121 + 109
= 798
Mean of Data without an outlier = 798/7 = 114
Data with an outlier: 108, 113, 105, 118, 124, 121, 109 , 61
Data points = 8
Sum of Data's = 108 + 113 + 105 + 118 + 124 + 121 + 109 + 61
= 859
Mean of Data without an outlier = 859/8 = 107.375
Mean affected by outlier 114 - 107.375 = 6.625
Mean reduced by 6.625 with an outlier
