Tests hypotheses about the mean of two populations whose distributions are continuous and symmetric but not necessarily normal.
Sampled data from the first variable x.
Sampled data from the second variable y.
Probability that this node incorrectly rejects a true null hypothesis.
Default: 0.05
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Hypothesis to accept if this node rejects the null hypothesis that the two variable populations have a common mean.
Name | Value | Description |
---|---|---|
mean(x) != mean(y) | 0 | The mean of the first population is not equal to the mean of the second population. |
mean(x) > mean(y) | 1 | The mean of the first population is greater than the mean of the second population. |
mean(x) < mean(y) | -1 | The mean of the first population is less than the mean of the second population. |
Default: mean(x) != mean(y)
A Boolean that indicates whether to reject the null hypothesis.
True | p value is less than or equal to significance level. Reject the null hypothesis and accept the alternative hypothesis. |
False | p value is greater than significance level. Accept the null hypothesis and reject the alternative hypothesis. |
Smallest significance level that leads to rejection of the null hypothesis based on the sample sets.
