Q. Select the outlier in the data set.\newline9,72,78,81,88,92,98,999, 72, 78, 81, 88, 92, 98, 99
  1. Identify Data Set: Identify the data set and list the numbers in order to observe any number that stands out significantly from the rest.\newlineData set: 9,72,78,81,88,92,98,999, 72, 78, 81, 88, 92, 98, 99
  2. Calculate Statistics: Calculate the range, mean, and standard deviation of the data set if necessary to identify the outlier. However, in this case, we can visually inspect the data set to see if any number is significantly different from the others.
  3. Visual Inspection: By visual inspection, we can see that the number 99 is significantly lower than all other numbers in the data set. The rest of the numbers are all above 7070, which makes 99 stand out as a potential outlier.
  4. Determine Outlier: Determine if 99 is an outlier by comparing it to the rest of the data set. Since all other numbers are closely grouped together and 99 is far away from the group, we can conclude that 99 is the outlier.
