## How do you use Z.TEST in Google Sheets?

Z.TEST is a statistical function that can be used in Google Sheets to determine the probability that two samples are drawn from the same population. It can be used to test whether the means of two samples are equal, or to test whether the proportions of two samples are equal. The Z.TEST function takes two input values, the first of which is the sample mean, and the second of which is the standard deviation of the sample.

## What is the syntax of Z.TEST in Google Sheets?

Z.TEST is a function in Google Sheets that calculates the z-score for a given set of data. The syntax for Z.TEST is as follows: Z.TEST(x, mu, sigma) where x is the data set, mu is the mean of the data set, and sigma is the standard deviation of the data set. The z-score is a measure of how far a given data point is from the mean of the data set.

## What is an example of how to use Z.TEST in Google Sheets?

Z.TEST is a function in Google Sheets that can be used to determine the statistical significance of a difference between two groups of data. To use Z.TEST, you first need to create a table with two columns, one for the group name and one for the data. In the first row of the table, list the group names. In the second row, list the data for the first group. In the third row, list the data for the second group. To use Z.TEST, enter the following formula in the cell where you want the results: =Z.TEST(A1:A2,B1:B2)

## When should you not use Z.TEST in Google Sheets?

There are a few occasions when you should not use Z.TEST in Google Sheets. First, if you are testing whether two numbers are equal, you should use the =equal() function instead. Second, if you are testing whether a number is within a certain range, you should use the =in() function. Finally, if you are testing whether a number is greater than or less than another number, you should use the =gt() or =lt() functions, respectively.
