Q. Select the outlier in the data set.6,62,64,70,75,76,82,92If 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: 6,62,64,70,75,76,82,92To find the outlier, look for a number that is significantly different from the rest.Outlier: 6 (significantly lower than the other numbers)
Calculate Mean: Step 2: Calculate the mean of the original data set.Mean = (6+62+64+70+75+76+82+92)/8Mean = 527/8Mean = 65.875
Calculate New Mean: Step 3: Calculate the mean of the data set without the outlier.New data set without outlier: 62,64,70,75,76,82,92Mean = (62+64+70+75+76+82+92)/7Mean = 521/7Mean = 74.4286
Compare Means: Step 4: Compare the two means to determine if the mean increases or decreases.Original mean: 65.875New mean without outlier: 74.4286Since 74.4286 is greater than 65.875, removing the outlier increases the mean.
