This applet is designed to allow you to draw samples from a particular population with a known mean ( = 0), calculate the mean, standard deviation, and t for each sample, and plot the results. Since we know that the null is true ( = 0), the resulting values for the sampling distribution of the mean.
The applet is shown below
Click on the buttons at the bottom to generate random samples. The resulting t-statistic is plotted in the histogram. |
