You can put this solution on YOUR website! 1.Conduct an ANOVA comparing the anxiety levels (at posttest only) of participants across all three treatment conditions: CBT, psychodynamic, and supportive therapy.

Ho: The means are equal
Ha: at least one of the means is different
----------
Using a TI-84 I conducted ANOVA on the three lists and
got the following:
test stat: F = 15.21
p-value = 0.0045
Conclusion: Since the p-value is less than 5%
reject Ho at the 5% significance level.
------------------------------
2. Conduct post hoc tests, if needed.
3. Report your analyses in the APA format and one to two sentences interpreting each of your results.
