Question

Sarah's scores on tests were 79.75.2.0.72.2.1

85, and 78.
Please find the first and the third quartiles.​

Answer 1

Lower Quartile is 1

Upper Quartile is 79

Explanation:

Put all the values in order

0, 1, 2, 72, 75, 78, 79, 85

Divide the values (find the middle value) : 72 and 75 are in the middle

There are three numbers on the right now and three on the left:

0, 1, 2 78, 79, 85

1 is in the middle of the values on the left.

79 is in the values on the right

Therefore 1 and 79 are the upper and lower quartiles.
