document.write( "This problem will introduce the learner into a technique called Analysis of Variance.  For this course we will only conduct a simple One-Way ANOVA and touch briefly on the important elements of this technique.  The One-Way ANOVA is an extension of the independent –t test that can only look at two independent sample means.  We can use the One-Way ANOVA to look at three or more independent sample means.  Use the following data to conduct a One-Way ANOVA:\r<BR>\n" );

document.write( "b)	If the results are significant to the following:  Click analyze, then click Compare Means, and then select one-way ANOVA like you did previously.  Now click Post Hoc.  In this area check Tukey.  If there is a significant result, we really do not know where it is.  Is it between group 1 and 2, 1 and 3, or 2 and 3?  Post hoc tests let us isolate where the level of significance was.  So if the results come back significant, conduct the post hoc test as I mentioned above and explain where the results were significant.<BR>\n" );
