Tip:If you’re asked to find the “standard error” for a sample, in most cases you’re finding the sample error for themeanusing the formula SE = s/√n. There are different types of standard error though (i.e. for proportions), so you may want to make sure you’re calculating th...
The program subtracts 0.0261 from each of the 200 resample means, squares each of these 200 differences, and adds the squared differences together. The result is 0.835. The program then calculates an estimate of the standard error of the sample mean. The estimated standard error of the sample ...
This chapter deals with how you can use Excel to find the average (i.e., "mean") of a set of scores, the standard deviation of these scores (STDEV), and the standard error of the mean (s.e.) of these scores. All three of these statistics are basic to the study of statistics ...

2.The smaller the standard deviation of x¯, the more closely the possible values of x¯(the possible sample means) cluster around the mean of x¯. 3.The mean of x¯ equals the population mean. the standard error ofx¯变少,所以,sample errors 变少,In general, the standard deviat...
