How to Find the Mean in Simple Random Sampling
Hi, I'm Charlie Kasov, and this is how to find the mean in simple random sampling. Now the mean in a random sample is very straightforward as long as you know what your sample size is. So for sample size we'll say n. And let's say it's 20. So if you have a sample of 20, you find the mean by taking the values for all 20, adding them up and dividing by 20 and that's your mean. So the mean equals the total over the number of we'll call them things or values. In this case the sum of all the values divided by 20 values. Now this is a mean that doesn't account for the standard error but just for the purposes of finding the mean it's total over number of values.
