Why do we use an ANOVA instead of doing multiple T-tests?
Homework Answers
The 't' test compares means between two samples & is simple to conduct, but if there is more than two condition in an experiment a ANOVA is required. The fact the ANOVA can test more than one trearment is a major advantage over other statistical analysis such as the 't' test.ANOVA use an F ratio as its significance statistic which is variance because it is impossible to calculate the sample means difference with more than two sample.

Which of the following is the best reason why one-way ANOVA should be used instead of running several t-tests when there are more than two experimental groups? A. Doing several t-tests means you might forget which variables you have compared B. t-tests and ANOVA require different levels of measurement for their dependent variable C. Performing several t-tests raises the probability of making at least one Type I error D. Performing several t-tests raises the probability of making at least one...

One-way ANOVA test and t-tests compare means. Which of the following should you consider to select the One-way ANOVA over multiple t-tests when you have more than two groups? A. Multiple t-Tests will increase the likelihood of a Type I Error. B. Multiple t-Tests will decrease the likelihood of saying something is significant when it is not. C.
