The following data were obtained from a repeated-measures study comparing 3 treatment conditions. Use a repeated-measures ANOVA with a=.05 to determine whether there are significant mean differences among the three treatments (do all 4 steps of conducting a hypothesis test!!): Person Treatment 1 Treatment 2 Treatment 3 Person Totals A 0 2 4 P=6 N=15 B 0 3 6 P=9 G=60 C 3 7 8 P=18 D 0 7 5 P=12 E 2 6 7 P=15 M=1 M=5 M=6 T=5...

A-3. [10]. What assumption do you have to justify for the use of the diﬀerences-in-diﬀerences method for estimating causal eﬀects? What would you check in the data to provide evidence in support of this assumption?

) Explain when you will use the test statistic and when you will use the test statistic . 2) Explain why using the smaller of n1 − 1 or n2 − 1 degrees of freedom to determine the critical t instead of is more precautious. 3) you learned how to test hypotheses regarding two sample proportions. Explain when you will use the test statistic and when you will use the test statistic .

Question: Provide an example of a within-subjects research study on which you could use a repeated measures ANOVA to analyze the data. Why is the within subjects design considered "better" than the between subjects design?

If MAPE and MAD indicate different methods, how do you choose which method to use?

If MAPE and MAD indicate different methods, how do you choose which method to use? You always trust MAPE better. You aslways trust MAD better. You have to use your judgement. You can not choose a method.You should not work on this specufuc project anymore

T statistic Why do we use the t statistic? What is standard error? What’s the difference between a one-sample t-test, an independent measures t test, and a repeated measures t-test? Walk through the 5 steps of hypothesis testing using a one-sample t-test. What are the assumptions of the t test? One-way ANOVA There are two sources of variation. What are they? Why do we care about them? Why do we use ANOVA? In other words, why don’t we just use...

Statistics exercises One-way repeated measures ANOVA 1. Suppose you are interested in learning if practice on the ACT improves test scores. You sample a random group of 10 people and ask them to take the ACT 1 time per week for 3 consecutive weeks. Use the data below to determine if practice improves test scores. Participant Test 1 Test 2 Test 3 1 18 23 24 2 20 22 26 3 21 24 23 4 19 25 28 5 20...
