Question

. A researcher wants to know if people who do community service have higher levels of empathy than people who do no community service (CS). Participants are divided into three groups: 10+ hours of CS (n = 14), 1-10 hours of CS (n = 12), and no CS (n = 10),. Each participant completes a measure of empathy in which scores can range from 0-100. What are the researcher’s independent and dependent variables? Independent= Community Service Dependent= Empathy What are the null and alternative hypotheses (use the appropriate symbols not words)? H0= H1=__________________ What is the appropriate test for the researcher to use?__________________ Why is that statistic appropriate? If applicable to the specific test: What are the test’s assumptions? What are the test’s df? What is the appropriate critical value? If the research obtains a test statistic of 3.03, would the researcher retain or reject H0? Should the researcher do any follow up tests or make any graphs/charts? Interpret the findings in APA style

Explanation / Answer

What are the researcher’s independent and dependent variables?

Answer:

Independent= Community Service

Dependent= Empathy

What are the null and alternative hypotheses:

Answer:

null hypotheses:1 = 2 = 3

alternative hypotheses:Means are not all equal.

What is the appropriate test for the researcher to use?

Answer:

One-Way ANOVA

Why is that statistic appropriate?

Answer:

Because the researcher is comparing 3 or more group means

What are the test’s assumptions? What are the test’s df?

Answer:

Normal distribution, Equal Variances, Independent observations

D.f:Ngroups-1; Npeople-Ngroups

What is the appropriate critical value?

We use here se the F table to determine critical value(s)

Please post remaining questions saperately.

Hope this will be helpfpul

Thanks and God Bless you :-)
