Comparing Two Means

Comparing Two Means

Go to this website and watch “Comparing Two Means.” You can find this as the 27th topic in the “Against All Odds” Series. The topics are how to recognize a two-sample

problem and how to distinguish such problems from one- and paired-sample situations. A confidence interval is given for the difference between two means, using the

two-sample t statistic with conservative degrees of freedom. Think about situations when using two means or t-statistic would be helpful and useful and please share

them with the class….can you think of other different and fun examples that might make the video more interesting?
