Question

After surveying 50 people, what measures of center can be calculated for these variables?

(1. mean, 2. median, 3. mode, 4. SD)

Put the corresponding number(s) next to the variable.

Weight:

Eye Color:

Graduating Class Rank:

Name:

ID#:

Answer 1

Weight is continuous random variable , therefore mean is appropriate measure of central tendency of weight .

Weight : mean .

There will be different eyes colors , therefore the central value of eyes colors will be that colour which occurred more so we need to calculate mode .

Eyes colors : mode .

Graduating calss rank of one or more student may be same I'm order to find central tendency we need to devide all observation into two parts and so we should calculate median.

Graduating class rank : median .

Central tendency of name of student can be find using mode of data.

Name : mode .

ID : median . Since we can easily ordered value and find median which will be appropriate measure of central value .

Above solution is correct with full explaination so please rate me high .
