Question

1. A group of children were asked how many hours a day they spend watching television. Determine the mean, mode, and median.

Answer 1

Use the midpoint of each interval as an estimate for the data point.

So our estimates are

0.5

1.5 1.5 1.5 1.5

2.5 2.5 2.5 2.5 2.5 2.5 2.5

3.5 3.5 3.5

4.5 4.5

5.5

Mode (most frequent) - clearly 2.5

Median : middle value . 18 values so take the mean of the 9th and 10th values (so mean of 2.5 and 2.5) so 2.5

mean : add up the 18 values and divide by 18 (you can do that)
