Data: Simple Graphs in RStudio
Background: As we have learned, a lot of thought goes into the design of a visualization. This week we review how the data types influence the graphing types.
Assignment:
Use RStudio to generate the list of simple graphs below using the dataset: dataset_price_personal_computers_Chaptr6.csv
The submission MUST include the screen captures of the multiple windows for each graph listed or 0 points will be earned
The windows are Code/or file contents, Console, Environment/Files (num observations and variables), Plots/Graphs
Graphs to Produce:
Pie Chart:
Create a pie chart for the computer ram
Label the RAM sizes for each amount of RAM discovered in the dataset formatted as 2GB, or 4GB, or 16GB, as examples
Title the pie chart as “Computer Ram”
Color the pie chart using the rainbow option
Bar Plot:
Create a barplot of the computer screen sizes
Label the x-axis as “Screen Sizes”
Label the y-axis as “Frequency”
Title the barplot as “Computer Screen Sizes”
Color the bars in the barplot any color you wish.
Histogram:
Create a histogram of the computer prices
Label the x-axis as “Prices”
Title the histogram as “Computer Prices”
Give the histogram any color you wish.
Box Plot:
Create a boxplot of comparing the computer price and premium category
Label the y-axis as “Price”
Label the x-axis as “Premium”
Title the boxplot as “Premium Computer Prices Distribution”
Color the boxplot any color you wish.
Scatter Plot:
Create a scatter plot of computer price and hard drive size
Label the x-axis as “Hard Drive Size”
Label the y-axis as “Price”
Title the scatter plot as “Computer Price vs Hard Drive Size”
Color the scatter any color you wish.
Your document should be an easy-to-read font in MS Word (other word processors are fine to use but save it in MS Word format). Your cover page should contain the following: Title, Student’s name, University’s name, Course name, Course number, Professor’s name, and Date.
Note: Each graph created must be submitted as a screen capture in the Word document showing all windows as previously listed. If all windows are not displayed 0 points will be earned.
