Single-factor ANOVA is a statistical method used to determine whether there are significant differences between the means of three or more groups. The SPSS software can be used to conduct this type of analysis, and the results will provide information on the variation between groups, the F-ratio, and the probability of obtaining the observed F-value by chance. In order to interpret the results of a single-factor ANOVA, it is important to understand the significance level, the degrees of freedom, and the effect size. The significance level determines the probability of observing an F-value as large or larger than the one obtained, assuming that there is no difference between the groups. The degrees of freedom refer to the number of scores that are free to vary in the analysis. Lastly, the effect size is a measure of the magnitude of the difference between the groups and can be calculated using different methods such as eta squared, partial eta squared, or Cohen's d.
