Data analysis csv

Data analysis csv:1) Read the income dataset, “zipIncome  Assignment.csv”, into R.

2) Change the column names of your data frame so that zcta becomes zipCode

and meanhouseholdincome becomes income.

3) Analyze the summary of your data. What are the mean and median average

incomes?

4) Plot a scatter plot of the data. Although this graph is not too informative, do

you see any outlier values? If so, what are they?

5) In order to omit outliers, create a subset of the data so that:

 $7,000 < income < $200,000 (or in R syntax, income > 7000 & income < 200000)

6) What’s your new mean?

7) Create a simple box plot of your data. Be sure to add a title and label the axes.

HINT: Take a look at: https://www.tutorialspoint.com/r/r_boxplots.htm (specifically,

Creating the Boxplot.) Instead of “mpg ~ cyl”, you want to use “income ~ zipCode”.

In the box plot you created, notice that all of the income data is pushed towards

the bottom of the graph because most average incomes tend to be low. Create a

new box plot where the y-axis uses a log scale. Be sure to add a title and label the

axes. For the next 2 questions, use the ggplot library in R, which enables you to

create graphs with several different types of plots layered over each other.

8) Make a ggplot that consists of just a scatter plot using the function

geom_point() with position = “jitter” so that the data points are grouped by zip

code. Be sure to use ggplot’s function for taking the log10 of the y-axis data.

(Hint: for geom_point, have alpha=0.2).

9) Create a new ggplot by adding a box plot layer to your previous graph. To do

this, add the ggplot function geom_boxplot(). Also, add color to the scatter

plot so that data points between different zip codes are different colors. Be

sure to label the axes and add a title to the graph. (Hint: for geom_boxplot,

have alpha=0.1 and outlier.size=0).

10) What can you conclude from this data analysis/visualization?

Note:

You are required to copy and paste all your R programming commands to your document and

you should take the screenshot of your graphs.

Your Word document should contain the report of the analysis of your data.

Your Word document should have a distinct cover-page and reference-page as usual.

Useful commands:

install.packages(“ggplot2”)

library(ggplot2)
