Explanation:

Given the daily high temperatures for one winter week in Albany below:

`39,42,34,37,39,44,41`

First, arrange the numbers in ascending order:

`34,37,39,39,41,42,44`

(a)Mean

To find the mean, add the numbers together and divide by the number of items, 7:

`Mean=(34+37+39+39+41+42+44)/(7)=(276)/(7)\approx39.43`

(b)Median

The median is the number in the middle of the dataset.

The number in the middle = 39

Median = 39

(c)Mode

The mode is the number that appears the most.

Mode = 39

(d)Range

The range is the difference between the highest and lowest numbers.

`Range=44-34=10`

The range is 10.
