The ____ is the value calculated for the arithmetic average. (a) Mean
(b) Median
(c) Mode
(d) All above
✅ Correct option: (a) Mean
Explanation:
The mean is the arithmetic average of a dataset and is calculated by summing all the values and dividing by the total number of values. It is the most commonly used measure of central tendency in statistics. The median represents the middle value, and the mode represents the most frequent value, but neither of these involves arithmetic averaging. Therefore, only the mean fits the definition of arithmetic average. The mean is particularly useful in statistical analysis because it allows further calculations such as variance and standard deviation, which are essential in inferential statistics. Hence, the correct option is mean.
