In this article, We will learn to calculate various types of standard error in Excel. First, we will learn the Standard Error of Mean. The standard error of the mean (SEM) measures the sample meanâ€™s deviation from the population mean. We will learn different methods to calculate the standard error of mean.

We will also cover SEM(Standard Error of Mean), Standard error of regression, and standard error of skewness. Skewness represents the degree of asymmetry in a given set of data. In a distribution, when the tail on the left side is longer, you may say that the distribution is negatively skewed (left-skewed). On the contrary, a distribution will be positively skewed (right-skewed) if the tail on the right side is longer than on the left side.

## What Is Standard Error?

When dealing with real-world data, it is not always possible to use data from the entire population. As a result, we usually work with random samples drawn from the population. The standard error of the sample indicates how close its mean is to the true population mean.

## How to Calculate Standard Error of Mean in Excel

In mathematics, the standard error of mean can be calculated by dividing the Standard Deviation and the square root of sample size.

`SEM= SD/âˆšn`

Here **SD** is the standard deviation and **n** is the sample size.

### 1. Using Excel Formula

- We can calculate Standard Error in Excel using the Excel Formula given below. We will use
**the STDEV.S function**to calculate standard deviation.**The COUNT function**will calculate the number of examples.

`=STDEV.S(C5:C18)/SQRT(COUNT(C5:C18))`

### 2. Using Formulas Tab

- Go to the
**Formulas**tab and then**Insert Function**.

- Choose the
**Statistical**category from the dropdown menu and select**STDEV.S**and click**OK**.

- Then give the input range
**C5:C18**and click**OK**.

- Now enter the formula to calculate the standard error of mean.

`=C19/SQRT(COUNT(C5:C18))`

### 3. Using Data Analysis ToolPak

- For the data analyzing tool pack, go to the
**File**tab.

- Select
**Options**.

- From the
**Excel Options**window, select**Add-ins**. Then select**Analysis Toolpak**in the**Active Application Add-ins**group and click on the**Go**button.

- Select
**Analysis Toolpak**from the**Add-ins**window and click**OK**.

- Then go to
**Data**>>**Data Analysis**.

- Then select
**Descriptive Statistics**in the**Data Analysis**window and select**OK**.

- Then again give the input range, select
**Columns**as the**Grouped By**option, Select**Labels in first row**checkbox, enter the output range, select**Summary statistics**and click**OK**.

- Then we will get a summary of different calculations.

- Then look for the standard deviation. Copy the value and paste it on the
**C19Â**cell.

- Now enter the formula and calculate standard error of mean.

`=C19/SQRT(COUNT(C5:C18))`

## How to Calculate Standard Error of Skewness in Excel

Now, weâ€™ll learn how to calculate standard error of skewness in Excel.

- Select cell
**C17**and enter the given formula.

`=COUNT(C5:C16)`

- Calculate the mean using the formula given below.

`=AVERAGE(C5:C16)`

- Select cell
**C19**and calculate the standard deviation using the formula.

`=STDEV(C5:C18)/SQRT(COUNT(C5:C18))`

- Calculate standard error using the formula given below.

`=C19/SQRT(C17)`

- Now calculate the standard error of skewness entering the formula in the
**C21**cell.

`=SQRT((6*C17*(C17-1))/((C17-1)*(C17+1)*(C17+3)))`

## How to Calculate Standard Error of Regression in Excel

Letâ€™s learn how to calculate standard error of regression in Excel.

- Go to
**Data**>>**Data Analysis**.

- Select
**Regression**in**Data Analysis**window and click**OK**.

- Select cell
**C5:C16**as**Input Y Range**and**B5:B16**as**Input X Range**. Then select the**Output Range**and click**OK**.

- Now copy the standard error and paste it into the
**C18Â**cell.

## How to Add Standard Error Bars in Excel

- Select the data range
**B5:C18**. Go to**Insert**>>**2-D Column**. This will create a bar chart.

- Select the chart and click on
**(+)**icon and check**Error Bars**. This will add error bars on the top of the chart.

## What Are the Differences Between Standard Error and Standard Deviation?

The standard deviation (SD) of a set of data is the amount of variation or dispersion from its mean. A high standard deviation indicates that the data points are widely separated from the mean, whereas a low standard deviation indicates that the data points are relatively close to the mean.

The standard error of the mean (SEM) measures the sample meanâ€™s deviation from the population mean. The standard error indicates how well the sample mean represents the true population mean and how much error is to be expected when sampling from the same population multiple times.

## Conclusion

Understanding and using these measures correctly is critical for interpreting results, making valid inferences, and drawing reliable conclusions in a variety of fields of study. Standard errors, remember, provide valuable insights into the uncertainty associated with estimates, allowing researchers and analysts to make informed decisions and draw robust conclusions from their data.
