The document provides guidance on reporting the results of a single sample t-test in APA format. It includes an example result that states there was no statistically significant difference in calculus anxiety scores between a sample of 30 students and the general college student population based on a t-value of 1.03 and p-value of 0.434. Key elements to report include the sample mean and standard deviation, degrees of freedom, t-value, and p-value.

reported in APA.

13. 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.

reported in APA.
There was no statistically significant difference in
calculus anxiety scores between a sample of 30

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.

18. 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 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.

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.
