Regression analysis of these data
Kong et al. (2012) studied mutation rates in Icelandic
children, specifically looking at mutations in single nucleotide polymorphisms
(SNPs). As part of this study, they also recorded the age (in years) of the
mother and the father. Part of their data are given below:

A)
If you were to do a regression analysis of these data,
which would be the dependent variable and which would be the independent
variable? Explain your reasoning!
B)
What is the regression equation for the relationship
between these two variables? For this part, I want you to show me the steps
you’d take to calculate the slope and the Y-intercept. You can check your
results using Excel or some other program, but you will not get full credit if
you simply give me the equation as generated by Excel or another program. (This
is all a fancy way of saying you need to calculate this part by hand!).
C)
Determine whether the slope of this equation is
significantly different from zero, using a regression ANOVA approach.

Word document for this assignment. You will create this Word document
by cutting and pasting SPSS output into Word. Name the file in the
following format: lastnamefirstinitialPSY7107-9.doc (example:
smithbPSY7107-9.doc).Begin by downloading the following SPSS data setActivity 9.sav (found in Books and Resources for this Week)This
week’s assignment consists of two parts. In the first part, you will
utilize an existing dataset to compute a factorial ANOVA. All SPSS
output should be pasted into your Word document. In the second part, you
will be asked to create a hypothetical ANCOVA output table (for
variables related to your area of interest). Part A. SPSS AssignmentThe
“Activity 9.sav” file contains a dataset of a researcher interested in
finding the best way to educate elementary age children in mathematics.
In particular, she thinks that 5th grade girls do better in small class
sizes while boys excel in larger classes. Through the school district,
she has arranged a pilot program in which some classroom sizes are
reduced prior to the state-wide mathematics competency assessment. In
the dataset, you will find the following variables:Participant: unique identifierGender: Male (M) or Female (F)Classroom: Small (1) – no more than 10 childrenMedium (2) – between 11 and 19 childrenLarge (3) – 20 or more studentsScore – final score on the statewide competency assessment.Now do the following:Exploratory Data Analysis.Perform
exploratory data analysis on all variables in the data set. Realizing
that you have six groups, be sure that your exploratory analysis is
broken down by group. When possible, include appropriate graphs to help
illustrate the dataset.Give a one to two paragraph write up of the data once you have done this.Create an APA style table that presents descriptive statistics for the sample.Factorial ANOVA. Perform a factorial ANOVA using the “Activity 9.sav” data set.
Is
there a main effect of gender? If so, explain the effect. Use post hoc
tests when necessary (or explain why they are not required in this
specific case).Is
there a main effect of classroom size? If so, explain the effect. Use
post hoc tests when necessary (or explain why they are not required in
this specific case).Is there an interaction between your two variables? If so, using post hoc tests, describe these differences.Is
there support for the researcher’s hypothesis that girls would do
better than boys in classrooms with fewer students? Explain your answer.Write
up the results in APA style and interpret them. Be sure that you
discuss both main effects and the presence/absence of an interaction
between the two.Part B. Applying Analytical Strategies to an Area of Research InterestBriefly restate your research area of interest.Analysis
of Covariance. Using your area of interest, identify one independent
and two dependent variables, such that the dependent variables would
likely be covariates. Now, assume you conducted an ANCOVA that shows
both the first independent variable as well as the covariate
significantly predicts the dependent variable. Create a mock ANCOVA
output table (see SPSS Output 12.6 in your text for an example) that
supports the relationship shown above. Report your mock finding APA
style.You should now have the following file:lastnamefirstinitialPSY7107-9.doc (example: smithbPSY7107-9.doc)
