How does t-test with unequal variance determine df?
help me -
For a two-sample t-test with unequal variances, df depends on sample variances and sample sizes. In the Office Online Help of Excel 2003, select the "About statistical analysis tools" topic, expand the "t-Test" section, and you'll see the formula for df. Or, look at the "Unequal sample sizes, unequal variance" section of http://en.wikipedia.org/wiki/Student's_t-test - Mike Middleton http://www.DecisionToolworks.com Decision Analysis Add-ins for Excel "help me" <help wrote in message ... We should have a df= 48 with n=50. We have df=44. |
