What is the difference between a population mean and a sample mean? Are there any circumstances when they will be the same?

hockeychick23 · Answer

Well population means are usually a lot bigger than sample means because theres more numbers

valpey · Answer

Try restating that. The means aren't necessarily larger or smaller.

hockeychick23 · Answer

oh right, so would the smaller the number of samples bring the largest numbers because theres less to divide by?

valpey · Answer

Hmmm. The sample size is the number of observations we collect.

valpey · Answer

The population mean would be the same as the sample mean if your sample size was the same as the size of your population.

hockeychick23 · Answer

so then would any of them even be relevant? because doesn't one of the answers have to be right?

valpey · Answer

The question isn't worded perfectly, but the point is that if you have a larger sample size, the mean of the sample means will become more and more accurate.

hockeychick23 · Answer

so it would be the largest number (63) then right?

valpey · Answer

Yeah

ok thanks!
