Question

Approximately what percent of data values in a sample are greater than or equal to the third quartile?

Answer 1

Answer:

25% of data lies greater than or equal to the third quartile.

Step-by-step explanation:

The quartiles divides the whole data in four equal part.

The first quartile is the quartile that divides the first 25% of the data with the rest 75% of data.

The second quartile also known as the median divides the data into two equal parts that is it divides the first 50% of data with the second 50% of data.

The third quartile divides the first 75% with the remaining 25% of data.

We have to find the percent of data that are greater than or equal to the third quartile.

Thus, from definition of third quartile, 25% of data lies greater than or equal to the third quartile.

Answer 2

It would be 25% since the third quartile should be the number in the middle of the second half of a data set. which means it is 75% of the way through.
