Question

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.

Answer 1

Answer: A. 51.9, 52, 49, 6

Step-by-step explanation:

The given data : 49, 49, 54, 55, 52, 49, 55

${\text{Mean =}\dfrac{\text{Sum of observations}}{\text{Number of observations}}$

${\text{Mean =}\dfrac{363}{7}=51.8571428571\approx51.9$

For Median , first we arrange observations in order.

49, 49, 49, 52, 54, 55, 55

Median = Middlemost observation = 52

Mode = Most repeated observation = 49

Range = Maximum number -Minimum number

$=55-49=6$

Answer 2

The answer is A.
