The standard error of the mean can be reduced by ___.

B)reducing ó
C)both a and b

Question

Quizplus · Accepted Answer

Both increasing sample size and reducing ó (standard deviation) can decrease the standard error of the mean. Increasing sample size provides more data points and reduces random error, while reducing the standard deviation means there is less variability in the data. Therefore, both options can lead to a more precise estimate of the true population mean.
