Question

Fill in the blanks: Roughly, when arranged in increasing order, the uppermost $25\%$of the dataset are greater than or equal to _______ .

Short answer

When arranged in increasing order, the uppermost$25\%$ of the dataset are greater than or equal to the third quartile.

Step-by-step solution

Given Information

We have to find out that when arranged in increasing order, the uppermost $25\%$of the dataset are greater than or equal to which values.

Explanation

Now, as we know that the interquartile range is the difference between upper limit and lower limit i.e., the difference between third quartile and first quartile.

$IQR=Q_3-Q_1$

where $Q_3$is the third quartile in which values are greater than or equal to $75\%$of the values and which shows that uppermost $25\%$data set are greater than or equal to $Q_3$.

Hence, it shows that answer is third quartile range.
