Homework 6
Problems
DUE DATE: WEDNESDAY, FEBRUARY 12, 2020 by 11:59 PM ON GRADESCOPE
Grading:
• Part 1: Swirl Module will be graded.
• Part 2: 2 randomly selected problems will be graded. The rest of the problems will be taken
for completion points only.
This homework has a total of 10 problems.
Part 1: Swirl Module
1. In the console window where you can type in R code, type the following to load swirl:
library(swirl)
swirl()
2. R will ask you for your name. Type your name.
Follow the prompts on the screen. To exist swirl, press the Esc key. If you are already at the
prompt, type bye() to exit and save your progress. When you exit properly, you’ll see a short
message letting you know you’ve done so.
3. Complete Module 12: Looking at Data.
After completion
• When they ask “Would you like to receive credit for completing this course on
Coursera.org?”, type YOUR NAME (FIRST AND LAST).
• Hit enter.
• Print the screen. This shows that you have completed the assignment.
• Then for selection, type “0”.
4. Upload your screenshot as part of your Homework 6 submission.

Part 2 Directions: For the following, report your code as well as your final answer, unless noted.
Part 2 Problems:
1. For the following questions, use the file “Earthquakes.csv”. There is a header in the data.
This dataset consists of information about Worldwide Earthquakes of Magnitudes 6–6.9, 7–
7.9, and 8 for the years 2000–2007. This information came from usgs.gov.
(a) How many earthquakes are there per year?
(b) How many earthquakes are there per magnitude category (Magnitude)?
(c) For each magnitude category (Magnitude), find the average year that the earthquakes
occurred.
(d) Make a histogram displaying the frequency of earthquakes per year. Have the break
points be the years 2000, 2001, . . . , 2008. Make the histogram such that the cells are
right-open (left closed) intervals.
(e) Does it appear that any year had more earthquakes than the other years, i.e. are any
years outliers and why? If necessary, provide an appropriate chart.
2. For the following questions, use the file “glass.data.txt”. There is a header in the dataset and
is comma delimited.
Dataset information: The study of classification of types of glass was motivated by criminological investigation. At the scene of the crime, the glass left can be used as evidence. Column
information:
• ID: Id number
• RI: refractive index
• Na: Sodium (unit measurement: weight percent in corresponding oxide)
• Mg: Magnesium (unit measurement: weight percent in corresponding oxide)
• Al: Aluminum (unit measurement: weight percent in corresponding oxide)
• Si: Silicon (unit measurement: weight percent in corresponding oxide)
• K: Potassium (unit measurement: weight percent in corresponding oxide)
• Ca: Calcium (unit measurement: weight percent in corresponding oxide)
• Ba: Barium (unit measurement: weight percent in corresponding oxide)
• Fe: Iron (unit measurement: weight percent in corresponding oxide)
2
• Type: Type of glass (class attribute)

Questions:
(a) Find the sample size by glass type.
(b) Split data by group based on the Type of Glass Column. Report your code only.
Hint: https://stackoverflow.com/questions/19205806/undefined-columns-selectedwhen-subsetting-data-frame
(c) Create side-by-side histograms for Float Processed Building Windows (Glass Type 1) vs
Non-Float Processed Building Windows (Glass Type 2), where we are interested in the
frequency of Calcium. Make the histogram such that the cells are right-open (left closed)
intervals. Provide your code as well as your diagram.
(d) Create parallel boxplots (all on the same window) for the 3 Non-Window Glass categories
(containers, tableware, headlamps), where we are interested in Calcium. Provide your
code as well as your diagram.
(e) Create a stripchart for all types of glass, where we are interested in Calcium. Use the
jitter method. Report your code only.
