Question

A survey is taken from 10 women on the time spent on cooking, which is listed below.


Choose the measure that best represents the data.

• A. mean
• B. median
• C. mode
• D. suitable measure is not there.

Answer 1

The correct option is B median

The data set is

30, 30, 40, 40, 40, 40, 50, 50, 60, 60, 60, 90.

Mean = $\frac{sumofalldata}{numberofdata}$

Mean = $\frac{30+30+40+40+40+40+50+50+60+60+60+90}{12}$

= $\frac{590}{12}$

= 49.1666

= 49.17

For a set with an even number of values, the median is the mean of the two middle values.

Median = $\frac{40+50}{2}$

= $\frac{90}{2}$

= 45

The mode of the data set is the value or values that occur most often.

Mode = 40

Median is the best measure because the data set has an extremely high value(outlier) 90 as compared to other numbers in the data set.

Hence, the best measure that represents the data is its median.
