NORMSDIST

The `NORMSDIST` function returns the area under a normal distribution curve to the left of a specified value. This function is commonly used in statistics to calculate probabilities.

Usage

Use the `NORMSDIST` formula with the syntax shown below, it has 1 required parameter:

Parameters:
1. x (required):
The value for which you want to calculate the area under the normal distribution curve.

Examples

Here are a few example use cases that explain how to use the `NORMSDIST` formula in Google Sheets.

Calculate the probability of a value from a normal distribution

You can use the `NORMSDIST` function to calculate the probability of a value from a normal distribution by providing the value as the `x` argument.

Calculate the z-score of a value from a normal distribution

If you know the mean and standard deviation of a normal distribution, you can use the `NORMSDIST` function to calculate the z-score of a value by subtracting the mean from the value and dividing the result by the standard deviation.

Calculate the critical value of a normal distribution

You can use the `NORMSDIST` function to calculate the critical value of a normal distribution for a given level of significance by finding the value of `x` such that `NORMSDIST(x) = α/2`, where `α` is the level of significance.

Common Mistakes

`NORMSDIST` not working? Here are some common mistakes people make when using the `NORMSDIST` Google Sheets Formula:

Incorrect use of arguments

One common mistake is to use the wrong type or number of arguments. The NORMSDIST function only takes one argument, which should be a numerical value. If you provide more than one argument or a non-numerical value, you will get an error.

Missing parentheses

Another common mistake is to forget to use parentheses around the argument. The correct syntax for the NORMSDIST function is NORMSDIST(x), where x is the numerical value you want to evaluate. If you forget the parentheses, you will get an error.

Incorrect range reference

Sometimes users mistakenly reference a range of cells instead of a single cell. The NORMSDIST function only works with a single value, so if you reference a range of cells, you will get an error. Make sure you reference a single cell that contains the value you want to evaluate.

NORMDIST is a similar function to NORMSDIST, but it returns the probability density function instead of the cumulative distribution function. If you mistakenly use NORMDIST instead of NORMSDIST, you will get a different result than what you intended.

Incorrect interpretation of the result

One common mistake is to misinterpret the result returned by the NORMSDIST function. The function returns a probability value between 0 and 1, which represents the area under the standard normal curve to the left of the given value. Some users may interpret this value as a percentage or a decimal, which can lead to incorrect conclusions.

The following functions are similar to `NORMSDIST` or are often used with it in a formula:

• `NORMSINV`

The `NORMSINV` function calculates the inverse of the standard normal cumulative distribution for a specified value of x. It is commonly used in statistical analysis to transform data from a normal distribution to a standard normal distribution with a mean of 0 and a standard deviation of 1.

• `NORMDIST`

The `NORMDIST` function in Google Sheets calculates the normal distribution for a specified value, mean, and standard deviation. It returns the probability of a value occurring within a specified range of a normal distribution. It is commonly used in statistics, finance, and science to analyze data and make predictions.

• `NORMINV`

The `NORMINV` function returns the inverse of the normal cumulative distribution for a specified value, mean, and standard deviation. It is commonly used in statistics to find the value at which a given percentage of observations lie below that value.
