Perform a Two-way analysis of variance (ANOVA) and report the
results using correct APA style; report whether significance was
found for Factor A, Factor B, and/or an interaction between Factors
A and B was found.
If the test statistic is significant, run a post hoc test to
determine between what groups significance was found.
Report an effect size for all significant results.
This is all the information they gave me.

Using the SATGPA data set in Stat2Data package. Test by using α=
.05.
1) Create the following three variables and then print out all
the six variables.
Create a new variable “SAT”, which is the sum of MathSAT and
VerbalSAT.
Create second new variable “SATLevel”, and assign the value of
“SATLevel” as 1 when
SAT<=1100, 2 when
1100<SAT<=1200, 3 when 1200<SAT<=1300, and 4 when
SAT>1300.

Multivariate analysis
Using the data provided, perform the following analysis:
Determine the explanatory and response variables.
Run a multivariate regression analysis on all three
variables.
Interpret the results by answering the following questions:
What is the calculated correlation coefficient? Do the sales
figures correlate with the marketing expenditure and price?
Comment on the coefficient of determination. What percentage of
the response data can be explained by the explanatory
variables?
Determine the multiple regression line equation in the
form:
sales^ =...

What kind of data lend themselves to perform an analysis of
variance and/or an independent-samples t test? Given your
answer above, why should you use analysis of variance instead of
just using an independent-samples t test?
