It depends on what you want to communicate. While the mean and standard deviation are descriptive statistics, the mean and standard error describes bounds.
To calculate the standard error of the mean by itself, use the one of the following formulas. is the data used to determine the standard deviation.
Dec 01, 2012 · In this video Paul Andersen explains the importance of standard deviation. He starts with a discussion of normal distribution and how the standard.
Step 2: Calculate standard error or standard deviation of the confidence interval is calculated. interval – Now we have all we need to calculate confidence interval. The formula to use is point estimate +- (critical value x standard.

(The TREND line is the "estimate" for which we calculate the standard error.).
Sep 23, 2015 · where: The range of values is the data used to determine the standard deviation.-and-The number is the size of all the possible random samples.
while the standard error of the mean, or SEM, measures how far the sample mean of the data is likely to be from the true population mean. The SEM is always smaller than the SD. The formula for the SEM is the standard deviation.
