One-Way ANOVA F-testsTo calculate a One-way ANOVA F-test in ExcelChoose the variables that you want to use as the independent, variable and the independentvariable, group variable that you want to calculate an independent t-test for. I will use Q1 andEthnicity.As you did for the Independent t-test, move the independent variable, Ethnicity, to anothercolumn. Move the dependent variable, Q1, next to it, and sort the data. Move data for separategroups into new columns and label those groups so your data looks as it does below.Click  on  Data  Analysis  and  drag  the  cursor  down  to  “ANOVA: Single Factor”  and  click  on  OK.

The following box will appear.Type in the cells that enclose the label and dataS1:Y7.Click  in  the  box  by  labels  (If  you  don’t  type  in  the  cell  for  the  label,  you  don’t  have  to  checkthis box.Click on Output range and give an empty cell for the results to be printed in. Here it is U13 toY31.Click on OK.

Your data will appear below. Notice that the means are labeled according to the column labels.

The variances are in blue. You can get standard deviations bysquaring this variance number for each group. #DIV/0! For Asians and Others means that the varianceand also the standard deviation could not be calculated because there was only person in that group. Theformula for variance has N-1 in the denominator and 1-1 0 so those variances could not be calculated.The F value and P value are in green. Remember you want the p value to be less than .05 for the F to besignificant meaning that these groups are significantly different on Q1. The degrees of freedom are inpurple.Your write-up should read:The means and standard deviations appear in Table 1 (you can do that table yourselves.) The F-test ofdifferences in means on Q1 between ethnic groups was not significantly different (F (6,12) .5, p .80).If this p was less than .05, you would need to say that there was a significant difference, and the groupwith the highest mean was different from the group with the lowest mean.

A One Way ANOVA is an analysis of variance in which there is only one independent variable. It can be used to compare mean differences in 2 or more groups. In SPSS, you can calculate one-way ANOVAS in two different ways. One way is through Analyze/Compare Means/One-Way ANOVA and the other is through Analyze/General Linear Model/Univariate. We .
