Question

For the given set of numbers, find the mean, the median,

and the mode. If necessary, round the mean to one
decimal place.
3.9, 45, 45, 59, 2, 5.4
The mean is (Round to one decimal place
as needed.)

Answer 1

The mean is 35.1, the median is 25.2, and there is no mode.

Step-by-step explanation:

To find the mean, we sum up all the numbers and divide by the total count. So, (3.9 + 45 + 45 + 59 + 2 + 5.4) ÷ 6 = 35.05 (rounded to one decimal place). Therefore, the mean is 35.1.

The median is the middle value when the numbers are arranged in ascending order. Firstly, we sort the numbers: 2, 3.9, 5.4, 45, 45, 59. The middle value is the average of the two numbers in the middle, which in this case is (5.4 + 45) ÷ 2 = 25.2. Thus, the median is 25.2.

The mode is the value that appears most frequently. In this case, both 45 and 59 appear twice, so there is no single mode. Therefore, the mode is undefined.
