A One-Way ANOVA, or analysis of variance, is a test used primarily in market research studies to compare the means of a single independent variable to that of the researcher's dependent variable. Before the age of modern technology, calculating a ANOVA was a complicated, time-consuming process, but today, it is relatively easy. If you have access to a TI-84 graphic calculator, and a complete, accurate data set, calculating a One-Way ANOVA is an easy way to see the results of your independent variable.

Open your data list by pressing "Stat edit," and enter in your recorded data as it appears written.

Press "Stat" and "Tests," selecting "ANOVA" from the available menu.

Enter the lists that you loaded under "Stat edit" so it appears on the screen as "ANOVA(L1, L2)." Press "Enter."

Tips & Warnings

  • Perform a Two-Way ANOVA by entering your second independent variable as another data set on your calculator.
  • Although it is possible to do statistical calculations on the TI-84, it is much more practical to use a program such as SPSS.
