Question

3. The temperature in New York City was recorded over the course of a week and are shown below:

Calculate the mean, median and mode for this data set.
Mean
35°, 42°, 38°, 25°, 17°, 20°, 36°

Answer 1

mean:3.428

median:35

mode:none

Answer 2

Mean: total sum/ amount

: 35 + 42 +.... /7

: 213/7

Mean = 30.4385.... Or 30.4° to 1d.p

Median: middle number, ordering from smallest to largest first.

: 17, 20, 25, 35, 36, 38, 42

Median = 35°

There is no Mode, all numbers appear once, none appears the most

Range: largest - smallest

: 42 - 17

Range = 25°

Hope this helps!
