Question

The upper quartile of a set of data is a number that __________. A. separates the bottom half of the data set from the upper half B. finding the mean of the data set remaining after removing the lower half C. separates the lower quarter of the data set from the upper three-quarters D. separates the lower three-quarters of the data set from the upper quarter

Answer 1

D. separates the lower three-quarters of the data set from the upper quarter

Step-by-step explanation:

The upper quartile is a line or a point that divides the upper half of a set of data in two exact parts, so when you get the median of the whole set of data, you take the upper half and calculate the median of that upper half, dividing the upper half in quartiles, and you get the division between the upper quartile and the other three quartiles.
