Q. Select the outlier in the data set. 2,69,73,77,78,79,82,92,99
Identify Outlier: To find the outlier, we first need to look at the data set and identify any number that is significantly different from the others.Data set: 2,69,73,77,78,79,82,92,99
Observe Data Set: We can observe that the number 2 is much smaller than all the other numbers in the data set. The rest of the numbers are all within a range of 69 to 99, which are relatively close to each other.
Confirm Outlier: To confirm that 2 is an outlier, we can calculate the mean and standard deviation of the data set and then determine if 2 falls far outside the range of the other values. However, in this case, it is quite evident without calculations that 2 is the outlier due to its significant difference from the rest of the data.
