Thompson’s Model of Strategic Choice: An example of using an ANOVA test
Thompson’s model of strategic choice (1967) provides a framework for an optimal decision-making approach that aligns with the decision-task demands. The primary aim of the study was to determine if success would occur when Thompson’s strategy was followed.
Ho: There will be no difference between the means of the decision approaches used, hence no
group will be more successful and the means will be the same.
Ha: There will be a difference between the means of the decision approaches, in that the mean of
the matched decision approach will be greater than the means of the other groups.
A one-way ANOVA was used because there were three group means (numerical level data), the sample was randomly selected and assigned to groups, and there was one IV (decision-approach) with three levels (matched, mismatch too quantitative, and mismatch too qualitative). Raw data met the assumptions for independent observations, homogeneity of variance, and was normally distributed. And, the test allows comparison of variance between groups to the variance within groups to determine if means are different (Bailey & Burch, 2002; Bernard, 2000; Gliner & Morgan, 2000; Maxim, 1999).

The alternate hypothesis was supported in that the mean scores for the matched decision approach was significantly different to the means of the too qualitative and too quantitative approaches, F (2, 313) = 1.245, p < .05. Hence, the means were different and the ANOVA significance test supported the Ha (i.e., the mean of the matched decision approach was statistically greater than the means of the other groups, hence was not different due to chance).
