# SKEW.P

The `SKEW.P` function in Google Sheets returns the skewness of a dataset, which is a measure of asymmetry. It measures whether the data is skewed to the left (negative skewness), to the right (positive skewness), or is symmetric (zero skewness). This function is commonly used in finance and economics to analyze the distribution of data.

## Usage

Use the `SKEW.P` formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:

Parameters:
1. value1 (required):
The first value or range of cells containing values of a dataset.
2. value2 (optional):
The second value or range of cells containing values of a dataset. This is an optional parameter.

## Examples

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

### Checking for skewness in a dataset

You can use `SKEW.P` to check if a dataset is skewed to the left, right, or is symmetric. For instance, if the skewness is negative, it means the data is skewed to the left (has a long tail to the left) and if it is positive, it means the data is skewed to the right (has a long tail to the right).

### Comparing skewness of two datasets

You can use `SKEW.P` to compare the skewness of two datasets. For example, if the skewness of dataset A is greater than that of dataset B, it means that dataset A is more skewed than dataset B.

### Analyzing financial data

In finance, `SKEW.P` can be used to analyze the distribution of financial data. For example, it can be used to measure the skewness of stock returns, which can help investors to make informed decisions.

## Common Mistakes

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

### Using the wrong data type

The `SKEW.P` function requires numeric data as input. If you provide text, boolean, or empty cells as input, the function will return a #VALUE! error. Make sure to check the data type of your input before using the function.

### Using a sample instead of a population

The `SKEW.P` function assumes that the input values represent a population, not a sample. If you use a sample instead of a population, you may get a biased estimate of the skewness. Use the `SKEW` function instead if you want to calculate the skewness of a sample.

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

• `SKEW`

The `SKEW` function calculates the skewness of a distribution based on a sample of data. Skewness is a measure of the asymmetry of a distribution around its average value. A positive skewness indicates that the distribution has an asymmetric tail extending towards more positive values, while a negative skewness indicates an asymmetric tail extending towards more negative values. The function can be useful in financial analysis, quality control, and other statistical applications.

• `STDEV.P`

The `STDEV.P` function is a statistical function that calculates the standard deviation of a population based on a sample of numerical data. It is commonly used to measure the amount of variation or dispersion in a dataset. The formula assumes that the input values represent the entire population, rather than a sample. If the input values represent a sample, you should use the `STDEV.S` function instead.

• `AVERAGE`

The AVERAGE function calculates the average (arithmetic mean) of the values passed to it. It is commonly used to find the average of a range of cells containing numerical data.

• `MEDIAN`

The `MEDIAN` function returns the median (middle) value of a set of numbers. It is commonly used to find the middle value in a range of data points. If the number of data points is even, it returns the average of the two middle values. This function can be useful in statistical analysis and data visualization.
