Q. Select the outlier in the data set.12,22,36,50,51,53,58,62,849If 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: 12,22,36,50,51,53,58,62,849Outliers are values that are much higher or lower than the rest of the data. 849 stands out as it is significantly higher than all other values.
Calculate Mean with Outlier: Step 2: Calculate the mean of the data set including the outlier.Mean = (12+22+36+50+51+53+58+62+849)/9Mean = 1193/9Mean = 132.56
Calculate Mean without Outlier: Step 3: Calculate the mean of the data set without the outlier.Mean without outlier = (12+22+36+50+51+53+58+62)/8Mean without outlier = 344/8Mean without outlier = 43
Compare Mean Changes: Step 4: Compare the two means to determine if the mean increases or decreases when the outlier is removed.Mean with outlier = 132.56Mean without outlier = 43Removing the outlier decreases the mean.
