What is the median of Variable A? Express answer to one decimal place.

OpenStudy (anonymous):

OpenStudy (anonymous):

Median is the sum of all values of the variable divided by the number of values you had

OpenStudy (anonymous):

That's the mean, not the median.

OpenStudy (anonymous):

In this case the number of values are 8 so you need to add each individual value and divide by 8

OpenStudy (anonymous):

Median is the middle value.

OpenStudy (anonymous):

ok so add them all and divide by 8?
