Question

The following temperatures were recorded in Pasadena for a week in April: 87, 85, 80, 78, 83, 86, 90. Determine the interquartile range. medal for answer

Answer 1

Interquartile Range is the third quartile minus the first quartile.

Let's find the 3rd and 1st quartiles.

78, 80, 83, 85, 86, 87, 90

85 is the middle number, so we split them in half:

78, 80, 83

So the first quartile is the middle number, which is 80.

86, 87, 90

So the third quartile is the middle number, which is 87.

So what's 87 - 80?
