Q. Select the outlier in the data set.If the outlier were removed from the data set, would the mean increase or decrease?Choices:(A)increase(B)decrease
- Identify Outlier: Identify the outlier in the data set.To find the outlier, we can look for a number that is significantly different from the rest of the numbers in the set. In this case, stands out as it is much higher than the other values.
- Calculate Mean with Outlier: Calculate the mean of the data set including the outlier.To find the mean, add all the numbers together and then divide by the number of values.Mean = Mean = Mean
- Calculate Mean without Outlier: Calculate the mean of the data set without the outlier. Remove the outlier and then calculate the new mean. New Mean = New Mean = New Mean
- Compare Means: Compare the two means to determine if the mean would increase or decrease upon removal of the outlier. The original mean with the outlier was approximately , and the new mean without the outlier is approximately . Since the new mean is lower, the mean would decrease if the outlier were removed.
