Q. Select the outlier in the data set.2,76,80,82,83,88,92,94If the outlier were removed from the data set, would the mean increase or decrease?Choices:(A)increase(B)decrease
Identify Outlier: Step 1: Identify the outlier in the data set.Data set: 2,76,80,82,83,88,92,94To find the outlier, look for a number that is significantly different from the rest.Outlier: 2
Calculate Mean Original: Step 2: Calculate the mean of the original data set.Mean = (2+76+80+82+83+88+92+94)/8Mean = 597/8Mean = 74.625
Calculate Mean Without Outlier: Step 3: Calculate the mean of the data set without the outlier.New data set: 76,80,82,83,88,92,94Mean = (76+80+82+83+88+92+94)/7Mean = 595/7Mean = 85
Compare Means: Step 4: Compare the two means to determine if the mean increases or decreases after removing the outlier.Original mean: 74.625New mean: 85Since 85 is greater than 74.625, removing the outlier increases the mean.
