How to Find the Standard Error in Excel Using the Data Analysis Toolpak This will copy the same formula to all the other cells on the right, and you will get standard errors for each of your samples! If your samples are placed in columns adjacent to one another (as shown in the above image), you only need to drag the fill handle (located at the bottom left corner of your calculated cell) to the right. To find the Standard errors for the other samples, you can apply the same formula to these samples too.
In other words, the standard error of a sample is its standard deviation from the population mean.
The standard error of a sample tells how accurate its mean is in terms of the true population mean. So we usually take random samples from the population and work with them. When working with real-world data, it is often not possible to work with data of the entire population.
