Reporting Results using APA

Here is how the results for a single-sample t-test are reported in APA.

There was no statistically significant difference in calculus anxiety scores between a sample of 30 students at University of Washington who just enrolled but had not yet attended a UW calculus course (M = 121, SD = 14.2) and the UW college students in general, t(29) = 1.03, p = .434.

The t value or the number of standard error units that separate the sample mean from the

population mean.

The p value or significance value. Meaning that out of 1000 replicated experiments we would be wrong 434

times if we rejected the null hypothesis. Therefore we will not reject the null hypothesis and consider the

sample and the population to be statistically similar.

times if we rejected the null hypothesis. Therefore we will accept the null hypothesis and consider the sample

For most researchers this is a desirable outcome so that they can use this sample to run experiments

and generalize the results to a larger population.
