11. Reporting Results using APA

12. Here is how the results for a single-sample t-test are
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.

M = the mean or average
of the sample

SD = Standard Deviation
of the sample

121, SD = 14.2) and the UW college students in general,
t(29) = 1.03, p = .434.
t(29) = 29 degrees of
freedom (df) or sample
size (30 – 1)

17. 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.

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.

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 accept 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.
