Chapter 9, Problem 9.82LM
What is the difference between a one-way ANOVA and a two-way ANOVA?
Expert Solution & Answer
To determine
To explain: The difference between the one-way ANOVA and two-way ANOVA.
Answer to Problem 9.82LM
One-way ANOVA has one factor with more than one level and two-way ANOVA has two factors, where each factor has more than one level.
Explanation of Solution
One-way ANOVA:
One-way ANOVA is a technique used for comparing two or more mean values.
It is used when the experiment has only one factor with two or more levels.
Two-way ANOVA:
Two-way ANOVA is a technique used to compare the means. It is used when the experiment has two factors and each factor has two or more levels.

Examine the Variables: Carefully review and note the names of all variables in the dataset. Examples of these variables include:
Mileage (mpg)
Number of Cylinders (cyl)
Displacement (disp)
Horsepower (hp)
Research: Google to understand these variables.
Statistical Analysis: Select mpg variable, and perform the following statistical tests. Once you are done with these tests using mpg variable, repeat the same with hp
Mean
Median
First Quartile (Q1)
Second Quartile (Q2)
Third Quartile (Q3)
Fourth Quartile (Q4)
10th Percentile
70th Percentile
Skewness
Kurtosis
Document Your Results:
In RStudio: Before running each statistical test, provide a heading in the format shown at the bottom. “# Mean of mileage – Your name’s command”
In Microsoft Word: Once you've completed all tests, take a screenshot of your results in RStudio and paste it into a Microsoft Word document. Make sure that snapshots are very clear. You will need multiple snapshots. Also transfer these results to the…
