Q. Select the outlier in the data set. \newline6,80,82,84,85,87,89,966, 80, 82, 84, 85, 87, 89, 96
  1. Identify data set: Identify the data set and look for the number that seems significantly different from the rest.\newlineData set: 6,80,82,84,85,87,89,966, 80, 82, 84, 85, 87, 89, 96\newlineBy observation, the number 66 stands out as being much lower than all other numbers in the set.
  2. Confirm outlier: To confirm the outlier, we can calculate the mean and standard deviation of the data set and see if the number 66 falls far from the mean compared to the other numbers. However, in this case, since the outlier is obvious by simple observation, we can conclude that 66 is the outlier without further calculations.
  3. Conclude outlier: Conclude which number is the outlier based on the observation in Step 11.\newlineThe number 66 is significantly different from the rest of the numbers in the data set, making it the outlier.
