Pick on correct answer: 6, 3.7, 5, 4

I think this one is 4 since it is an odd number you select what is in the middle correct?

-Variance is ______.

Pick on answer you think is correct:

*an average of the differences between observations and the median

*a sum of the differences between observations and the mean

*an average of the squared differences between observations and the mean

*an average of the squared differences between observations and the mode

This one i do not know or understand

-Variance is a measure of central tendency : True or False

I think this one is False
