To identify: Whether it makes sense to calculate the mean of the given data set.
Answer to Problem 1CQQ
No, it does not make sense.
Explanation of Solution
Given information:
The subjects of the study are assigned the numbers 1 to 410.
Concept used:
Nominal variables that are qualitative in nature. Here, the variable characterizes the data in such a way that they are placed into only one category. The numerical values in this variable just names the categories of the variable uniquely.
In this case, the numbers that are assigned to the subjects of the study will be considered nominal variables. These numbers are just to assign the labels to the subjects, it will be meaningless if one is calculating any numerical summary from this data.
Hence, it does not make any sense to calculate the average of these numbers as the numbers are just used to give labels to the subjects of the study.
Therefore, the answer is No.
