The APA Manual does not give guidance on t-test tables. Indeed, it is often more common for t-test results to be written in the text instead of being presented in a table. For example, one might say "Females were found to have significantly more knowledge of child development than males (t(106) = 2.73, p.05)." The degrees of freedom are placed Reporting the results of a t-test What to report? What a statistics program gives you: For a one-sample t-test, statistics programs produce an estimate, m (the sample mean), of the population mean μ, along with the statistic t, together with an associated degrees-of-freedom (df), and the statistic p. For a two-sample (independent) t-test, statistics programs usually display the sample means of each group, m A and m B, and the How do I report independent samples T-test data in APA style? “An independent-samples t-test was conducted to compare memory for words in sugar and no sugar conditions.” 2. Significant differences between conditions . You want to tell your reader whether or not there was a significant difference between condition means. You can report data from your own experiments by using the template below.

Statwing represents t-test results as distribution curves. Assuming there is a large enough sample size, the difference between these samples probably represents  

Following a ten day recovery period, rats (kept at 80 percent body weight) are tested for the number of chocolate chips consumed during a 10 minute period of time both with and without electrical stimulation. The testing conditions are counter balanced. Compute the appropriate t-test for the data provided below. SAS Help Center: ODS Table Names PROC TTEST assigns a name to each table it creates. You can use these names to reference the table when using the Output Delivery System (ODS) to select tables and create output data sets. These names are listed in Table 125.9.

scipy.stats.ttest_ind¶ scipy.stats.ttest_ind (a, b, axis=0, equal_var=True, nan_policy='propagate') [source] ¶ Calculate the T-test for the means of two independent samples of scores.. This is a two-sided test for the null hypothesis that 2 independent samples have identical average (expected) values.

This table below is a compilation of data from the Student t distribution. Anytime that a t-distribution is being used, a table such as this one can be consulted to perform calculations. This distribution is similar to the standard normal distribution, or bell curve, however the table is arranged differently than the table for the bell curve.

Django's unit tests use a Python standard library module: unittest . This module defines are going away.
