2-sample t-test for summary data
Compare sample means using the 2-sample t-test for summary values. P-values can be calculated for one- or two-tailed comparisons, or compare results to a specified significance level.
Inputs are:
- - mean values for each sample;
- - standard deviations for each sample;
- - sample sizes for each sample;
- - specified significance level;
- - number of digits to display in results; and;
- - whether test is one-tailed or two-tailed.
Outputs include:
- - difference in sample means;
- - standard deviation and standard error of the difference;
- - confidence limits (based on specified significance level) for the means and their difference;
- - t and P values for the difference in means and the appropriate number of degrees of freedom; and
- - a plot of the confidence limits.
