1.The independent variable is the community service which is categorical and divided into
three groups.The dependent variable, in this case, is the empathy score which ranges from 0100.
2.H0: The mean empathy scores across all groups are equal.
Ha: At least one of the mean empathy scores vary across the groups.
Ho:µ1=µ2=µ3
Ha:µ1≠µ2≠µ3
3.The appropriate test statistic is,”One way ANOVA.”
4.One way ANOVA is appropriate as we are comparing more than 2 groups.
5. Assumptions of one-way ANOVA are:
a)The response variable is approximately normally distributed.
b)The population variances are equal across groups.
c)Samples are independent.
6.
n=36 and k=3
Test degree of freedom =Between group df+Within group df = (3-1)+(36-3) =2+33 =35
7. Appropriate critical value =3.285, using Excel formula =F.INV.RT (0.05, 2,33)
8. The researcher should retain the n...
