Here are 10 test scores 50 74 76 77 78 79 80 80 82 84 The mean of these scores is 76 How does removing the outlier 50 affect the mean?
The mean is now: (74+76+77+78+79+80+80+82+84)/9 = 78.889. Since 50 is an outlier, the overall representation of the test score becomes more accurate since the majority of values lie between 74 and 84.
