WebA t test failed to reveal a statistically reliable difference between the mean number of older siblings that the PSY 216 class has (M = 1.26, s = 1.26) and 1, t(45) = 1.410, Let SPSS calculate the value of t for you. Lorem ipsum dolor sit amet, consectetur adipiscing elit. To find a specific function, simply click one of the function groups in the Function Group list. If you'd like to download the sample dataset to work through the examples, choose one of the files below: Sometimes you may need to compute a new variable based on existing information (from other variables) in your data.

This provides a measure coefficient can range from -1 to +1, with -1 indicating a perfect negative It's also possible to use COMPUTE syntax to compute or transform string variables (i.e., variables containing characters other than numbers).
