FISHER
TheFISHER
function returns the Fisher transformation of a given value. This transformation is commonly used in statistics to normalize a distribution and improve the accuracy of hypothesis tests and confidence intervals. The resulting value will always be between 1 and 1, with values closer to 1 indicating a stronger correlation between two variables.

Examples
Here are a few example use cases that explain how to use theFISHER
formula in Google Sheets.
Calculating correlation coefficients
The FISHER
function is often used to calculate correlation coefficients between two sets of data. By transforming the data using the Fisher transformation, the resulting correlation coefficient will have a more symmetric distribution and be more suitable for hypothesis testing.
Normalizing data
The Fisher transformation can be used to normalize data that does not follow a normal distribution. This can be useful when performing statistical analysis or building predictive models.
Working with confidence intervals
The Fisher transformation is commonly used when calculating confidence intervals for correlation coefficients or other statistical measures. By transforming the data, the resulting confidence intervals will have a more symmetrical distribution and be more accurate.
Common Mistakes
FISHER
not working? Here are some common mistakes people make when using the FISHER
Google Sheets Formula:
Incorrect argument type
FISHER formula requires a numerical value as an argument. If a nonnumerical value is provided, the formula will return an error. To correct this mistake, make sure the argument is a numerical value.
Invalid argument range
FISHER formula requires a value between 1 and 1 as an argument. If a value outside of this range is provided, the formula will return an error. To correct this mistake, make sure the argument falls within the acceptable range.
Missing argument
FISHER formula requires one argument to be provided. If no argument is provided, the formula will return an error. To correct this mistake, make sure to provide one argument.
Related Formulas
The following functions are similar to FISHER
or are often used with it in a formula:

CORREL
The
CORREL
formula returns the correlation coefficient between two sets of data. This coefficient represents the strength of the linear relationship between the two sets of data, with values ranging from 1 (perfect negative correlation) to 1 (perfect positive correlation). 
PEARSON
The
PEARSON
function calculates the correlation coefficient between two sets of data points,data_y
anddata_x
. This coefficient indicates how closely related the two sets of data are. A high correlation coefficient indicates a strong positive correlation, while a low coefficient indicates a weak or negative correlation. This function is commonly used in statistical analysis and data visualization. 
STDEV
The
STDEV
function calculates the standard deviation of a set of numbers. It measures the amount of variation or dispersion of a set of values from the average (mean) value. It is commonly used in statistics to determine the spread of a data set. The values can be supplied as individual cells, ranges, or constants. 
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.
