Use an ANOVA with α = .05 to determine whether there are any significant mean differences among the treatments.
The null hypothesis in words is
The Critical F-value is:
Note: Leave the two decimal places after the decimal point
The F-statistic is:
Note: If it is a decimal number with two or more than two places, leave only two decimal places after the decimal point and do not round.
Calculate η2
η2 is
Note: If it is a decimal number with two or more than two places, leave only two decimal places after the decimal point and do not round.
