Question

What is the range and interquartile range for 125, 136, 150, 119, 150, 143?

Answer 1

The range is 31 and interquartile range is 25.

Explanation:

Given:

Range and interquartile range for 125,136,150,119,150,143.

Now, arrange in order from ascending to descending we get:

119,125,136,143,150,150.

Then, the difference between the highest number to lowest number we get the range:

`150-119=31`.

And, for getting the interquartile range(IQR) subtract the lower quartile(Q1) from upper quartile(Q3) :

Q1= 125 (middle of the first half of the order).

Q3=150 (middle of the second half of the order).

So, IQR= Q3-Q1

`IQR=150-125`

`IQR=25`.

Therefore, the range is 31 and interquartile range is 25.
