Q. Select the outlier in the data set.7,67,73,78,81,83,87,93
Identify Outlier: To identify the outlier, we first need to look at the data set and see if there is a number that is significantly different from the others.Data set: 7,67,73,78,81,83,87,93
Observe Data Set: By observing the data set, we can see that the number 7 is much lower than all the other numbers, which are all above 60. This suggests that 7 is the outlier.
Confirm Outlier: To confirm that 7 is the outlier, we can calculate the range, mean, and standard deviation of the data set and see if 7 falls far outside the expected range of values based on the standard deviation. However, in this case, since 7 is so far from the other numbers and the rest of the numbers are relatively close to each other, we can confidently conclude that 7 is the outlier without further calculations.
