The correct answer is: A
Explanation
The formula (N + 1)/2 is used to determine the median of a dataset. The median is the middle value in a set of ordered numbers. When the dataset has an odd number of values, the formula (N + 1)/2 helps identify the position of the median value.
N represents the total number of values in the dataset. By adding 1 to N and dividing it by 2, we get the position of the median value within the ordered set.
For example, if we have a dataset with 9 values, (N = 9), the position of the median would be (9 + 1)/2 = 10/2
= 5.
This means the fifth value in the ordered set would be the median.
