What is the variance of this data to the nearest one hundredth? 10 12, 8, 2

OpenStudy (amistre64):

we went thru this yesterday http://openstudy.com/users/faded911#/updates/51b9f5eae4b0012787fa952f

OpenStudy (amistre64):

standard deviation is the square root of variance

OpenStudy (anonymous):

Yea and the answer was wrong

OpenStudy (amistre64):

then you did not provide all the information, or it was entered incorrectly

OpenStudy (amistre64):

since you did not provide an indication as to whether or not its a population, or a sample of a population. then the steps for population were assumed. but that was also addressed yesterday
