When working with data in Google Sheets, it’s essential to understand the concept of standard error. Standard error is a measure of the amount of variation in a set of data, and it’s a crucial statistic in many fields, including science, economics, and social sciences. In this article, we’ll explore how to find standard error in Google Sheets, and why it’s an important tool to have in your data analysis toolkit.
What is Standard Error?
Standard error is a measure of the amount of variation in a set of data. It’s a way to quantify the amount of uncertainty or randomness in a set of data. In other words, it’s a measure of how spread out the data is from the mean. The standard error is usually represented by the symbol “SE” and is calculated as the standard deviation of the sampling distribution of a statistic.
Why is Standard Error Important?
Standard error is important because it allows you to make inferences about a population based on a sample of data. It’s a way to quantify the amount of uncertainty in your results, and it’s essential for making informed decisions. In Google Sheets, you can use standard error to calculate the margin of error for a confidence interval, which is the range of values within which the true population parameter is likely to lie.
How to Find Standard Error in Google Sheets
In this article, we’ll show you how to find standard error in Google Sheets using a few simple formulas. We’ll also provide some examples and tips to help you understand the concept better.
Let’s get started!
How To Find Standard Error In Google Sheets
Standard error is a measure of the amount of variability in a set of data. It is an important concept in statistics and is often used to determine the margin of error in a sample mean. In this article, we will show you how to find standard error in Google Sheets.
What is Standard Error?
Standard error is a measure of the amount of variability in a set of data. It is calculated as the standard deviation of the sample mean, and is often used to determine the margin of error in a sample mean. The formula for standard error is:
SE = σ / √n

- SE is the standard error
- σ is the population standard deviation
- n is the sample size
How to Find Standard Error in Google Sheets
To find standard error in Google Sheets, you can use the following steps:
1. Enter your data into a Google Sheet.
2. Select the cell range that contains the data.
3. Go to the “Tools” menu and select “Script editor.”
4. In the script editor, create a new function to calculate the standard error. The function should take two arguments: the population standard deviation and the sample size.
5. Use the following code to calculate the standard error:
function standardError(populationStandardDeviation, sampleSize) {
return populationStandardDeviation / Math.sqrt(sampleSize);
}
6. Call the function by selecting the cell where you want to display the standard error, and typing the following formula:
=standardError(σ, n)
7. Replace σ with the population standard deviation and n with the sample size. (See Also: How To Combine Two Sets Of Data In Google Sheets)
Example
Suppose we have a sample of 25 scores with a mean of 80 and a standard deviation of 10. We want to find the standard error of the sample mean.
First, we enter the data into a Google Sheet:
| Score | Mean |
|---|---|
| 70 | 80 |
| 85 | 80 |
| 78 | 80 |
Next, we select the cell range that contains the data and go to the script editor. We create a new function to calculate the standard error:
function standardError(populationStandardDeviation, sampleSize) {
return populationStandardDeviation / Math.sqrt(sampleSize);
}
We then call the function by selecting the cell where we want to display the standard error and typing the following formula:
=standardError(10, 25)
The standard error is approximately 2.5. This means that the sample mean is likely to be within 2.5 points of the true population mean 95% of the time.

Frequently Asked Questions
What is the standard error in Google Sheets?
The standard error is a measure of the amount of variation in a set of data. It’s calculated as the standard deviation of the sampling distribution of a statistic. In Google Sheets, you can use the STDEVP function to calculate the standard error of a sample of data.
How do I calculate the standard error in Google Sheets?
To calculate the standard error in Google Sheets, you can use the following formula: STDEVP(A1:A100) / SQRT(COUNT(A1:A100)-1). This formula calculates the standard deviation of the sample data in cells A1:A100, and then divides it by the square root of the sample size minus one. You can enter this formula into a new cell in your Google Sheet to calculate the standard error.
What is the difference between standard error and standard deviation?
Standard deviation and standard error are both measures of variation, but they are used in different contexts. Standard deviation is a measure of the amount of variation in a single set of data, while standard error is a measure of the amount of variation in a sample of data. Standard error is typically used in statistical inference, such as hypothesis testing and confidence intervals, while standard deviation is used to describe the spread of a single set of data.
Can I use the STDEV function to calculate standard error in Google Sheets?
Yes, you can use the STDEV function to calculate standard error in Google Sheets, but you need to be careful. The STDEV function calculates the sample standard deviation, which is not the same as the standard error. To calculate the standard error, you need to divide the sample standard deviation by the square root of the sample size. You can do this by using the formula STDEV(A1:A100) / SQRT(COUNT(A1:A100)-1), as described above.
How do I use the standard error in Google Sheets for statistical analysis?
You can use the standard error in Google Sheets for statistical analysis by using it to construct confidence intervals and perform hypothesis testing. For example, you can use the standard error to calculate the margin of error for a sample proportion, or to test the mean of a sample against a known population mean. You can also use the standard error to calculate the sample size required to achieve a certain level of precision in your estimates.
