Question

Quizplus · Accepted Answer

The inner fences, also known as the interquartile range (IQR), can be determined by finding the middle 50% of the dataset. To do this, we need to find the median (middle value) of the dataset. From there, we can find the median of the lower half and the median of the upper half. The difference between these two values is the IQR or the inner fences. Out of the answer choices given, only C gives a range that includes the middle 50% of the data.
