Yes sure, Standard deviation is used to measure the amount of change or variability, while standard error measures, how far that sample will be true. Standard error is always less than standard deviation. In standard deviation, we need to calculate the variance for the formula, while in standard error we have to deal with the mean of the calculations.

“SD” or “standard deviation” determines the amount of variability or dispersion for a subject set of data from the mean. “SEM” or “standard error of the mean,” on the other hand, determines how far the sample mean of the data is likely to be from the true population mean. SEM is always smaller than SD.

Calculating SEM or Standard Error of the Mean

Both are frequently used in clinical experimental studies. Here, they are used to present the characteristics of the sample data and explain the statistical analysis results. But sometimes several researchers confuse the SEM and SD in the medical literature. Those researchers should remember that the computations for SD and SEM involves various statistical inferences where each of them with its own meaning.

SD is the dispersion of data in a normal distribution. This means SD indicates how accurately the mean represents sample data. SEM is the SD of the theoretical distribution of the sample means or the sampling distribution. SEM includes statistical inference based on the sampling distribution.
