Q. Select the outlier in the data set. 9,80,82,88,89,91,94,96,97
Identify Outlier: Identify the data set and look for the number that appears to be significantly different from the rest of the numbers.Data set: 9,80,82,88,89,91,94,96,97By observation, we can see that the number 9 is much smaller than all other numbers in the set.
Confirm Outlier: To confirm the outlier, we can calculate the mean and standard deviation of the data set and see if the number 9 falls far outside the range of the other numbers. However, in this case, since the difference is quite apparent and all other numbers are clustered in the 80s and 90s, we can conclude that 9 is the outlier without further calculations.
