| APPLET | SOURCE | DESCRIPTION |
|
| t-Test for Independent or Correlated Samples | Vassar Stats (Lowry) | Computes confidence intervals and performs hypothesis tests for the difference in two means from either independent or correlated populations based on data that is either entered or pasted into columns. more
  |
| Student's t-test: Comparison of two means | Univ. of Athens, Department of Chemisty | Expository material along with applet that allows user to conduct a t-test for two means, users enter demo data by clicking points on two number lines or can enter in values, calculates sample statistics, test statistic and p-value, and interprets the result. more |
| Test of Significance Calculator | Rossman/Chance Applet Collection | Computes and shows graphically test statistics and p-values for 1- or 2-tailed tests for one or two means or proportions based on summary data, also computes confidence intervals. more |
| Test Chooser | A Calculating Companion for Brunett's Critical Thinking | Helps user choose and perform appropriate statistical test for comparison of populations based on type of data, research question, number of samples, and whether data is matched or unmatched, computes test statistics, compares to critical values and provides interpretation, also calculates Cohen's d. more |
| t-Test for Independent or Correlated Samples | Vassar Stats (Lowry) | Computes confidence intervals and performs hypothesis tests for the difference in two means from either independent or correlated populations based on data that is either entered or pasted into columns. more |
| T-test on differences between means | Seeing Statistics (McClelland) in Fundamental Statistics for the Behavioral Sciences (Howell) | Calculates p-value for one or two tailed tests for the difference in two independent means based on summary statistics. more |
| Two Independent Sample T Test (pooled), Two Independent Sample T test (unpooled), Two Paired Sample | SOCR (Statistics Online Computational Resource) | Performs various two population tests for means given examples or user entered data. more |
| Two Populations Testing Means & Variances/Test of Hypothesis for Two Populations | A Collection of JavaScript E-labs Learning Objects (Arsham) | Tests 2-tailed hypotheses about two independent population means and variances based on up to 80 observations per sample (entered one by one) and provides interpretations of p-values, has option to test against difference values other than zero. more |
