Expert answer:Testing for One-Way ANOVA

Expert answer:Specifically, make sure the dependent
and independent variables (factor) are amenable to use in the ANOVA
(i.e., be sure to note levels of measurement).For this Assignment:Write a 2- to 3-paragraph analysis of your one-way ANOVA results for your research question. RESEARCH QUESTION: Is there a significant difference between the average family incomes in regards to the highest degree achieved?Include
any post-hoc tests with an analysis of the strength of any relationship
found (effect size). Also, in your analysis, display the data for the
output. Based on your results, provide an explanation of what the
implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output. I HAVE ATTACHED MY PREVIOUSLY DONE ASSIGNMENT IF IT HELPS

Research Design for One Way Anova
1.What is your research question?
Does the “RS HIGHEST DEGREE” has any impact on the family income or not? That is; is
there a significant difference between the average family incomes for different highest degrees?
2.What is the null hypothesis for your question?
•
Null hypothesis: the average family income is same for any highest degree
•
Alternative hypothesis: at least one group has different mean family income
3.What research design would align with this question?
A one way ANOVA is the most appropriate test that would align to the research question.
This is because the study will involve the comparison of mean among more than 2 groups.
4.What dependent variable was used and how is it measured?
•
Dependent variable-FAMILY INCOME IN CONSTANT $ (realinc)
•
Measured in- quantitative (ratio) scale with $ as the unit of measurement
SURNAME: 2
5.What independent variable is used and how is it measured?
•
Independent variable – RS HIGHEST DEGREE (degree)
•
Measured in- qualitative (ordinal) scale
6.If you found significance, what is the strength of the effect?
The obtained output is given below,

In this test, the p-value is small which implies that the result is significant with the effect
size 0.2005. Thus, the effect is weak.

7.Explain your results for a lay audience and further explain what the answer is to
your research question.
The results indicated that the mean for family income based on different highest degree
obtained are significantly different. This difference might have been caused by the highest
degree.
