I’m sure you’ve always heard that larger sample sizes are better. The reason becomes apparent when you understand how to calculate the standard error of the mean. Here’s the equation for the standard error of the mean. The numerator (s) is the sample standard deviation, which represents...
Standard error formula The equation of the standard error of the mean in its most compact form is: ∑i(xi−x‾)2N(N−1),N(N−1)∑i(xi−x)2, where: xixi is the ith measure; x‾x (x-bar) stands for the mean value of our dataset; and NN is the number of data poin...

Find the standard error of the given values of x and n: x=112, n=242. What is the effect of n on the standard error of the mean? Describe the two characteristics that will produce the largest value for the estimated standard error. ...
When indirect measurements are used to obtain rate-of-change data, an additional source of uncertainty is introduced that must be taken into account in the mean-rate and standard-error estimates. A procedure to account for this uncertainty is described. The chain rule of differentiation is used ...
