Formula Generator - TTEST function

The TTEST function is used to perform a t-test in Excel. It calculates the probability of observing the difference in means between two sets of data, assuming they come from the same population. The function takes four arguments: range1 and range2 are the two sets of data to be compared, tails specifies the number of distribution tails to use (1 for one-tailed test, 2 for two-tailed test), and type specifies the type of t-test to perform (1 for paired test, 2 for two-sample equal variance test, 3 for two-sample unequal variance test). The function returns the probability of observing the difference in means.

TTEST formula syntax.

The TTEST function in Excel is used to determine whether two sets of data are significantly different from each other. The syntax for the TTEST function is as follows: =TTEST(array1, array2, tails, type) - array1: The first set of data or range of cells. - array2: The second set of data or range of cells. - tails: Specifies the number of distribution tails to use in the calculation. It can be either 1 or 2, representing a one-tailed or two-tailed test, respectively. - type: Specifies the type of t-test to perform. It can be either 1, 2, or 3, representing paired, equal variance, or unequal variance tests, respectively. Note that both array1 and array2 must have the same number of data points. The TTEST function returns the probability associated with the t-test. If the probability is less than a chosen significance level (e.g., 0.05), it indicates that the two sets of data are significantly different.

Use Cases & Examples In these use cases, we use the TTEST function to perform a t-test on two sets of data. The TTEST function allows us to determine if there is a significant difference between the means of two samples.
