Project 3: Continuous Frequency Distribution

Problem:

• From the World Bank Data, do the following:
  • Construct histograms for Life Expectancy (lifeExp) for each continent and comment briefly on each. Use the rule of thumb ( 5 to 20) to decide on a reasonable number of bars).
  • Below are simple R-code to help you read and subset data by continent.

library(readr)
world_bank_data <- read_csv("world_bank_data.csv")
asa <- world_bank_data[world_bank_data$continent=="Asia",]
afr <- world_bank_data[world_bank_data$continent=="Africa",]
amr <- world_bank_data[world_bank_data$continent=="Americas",]
eur <- world_bank_data[world_bank_data$continent=="Europe",]
oce <- world_bank_data[world_bank_data$continent=="Oceania",]

Note:

• Before working on the project, make sure you have reviewed 2.2_2.3_Visualizing_Data.
• Write your code using R Script \((Ctrl + Shift + N)\) and make sure you save your script.
• Once you are done, test your code to make sure it is running and you are getting the desired results.
• Copy and paste all your histograms into a word document and make sure to comment briefly on each of them (in all you should be having five histograms). Below each histogram copy and paste the rcode you used to generate that histogram. Once you are done, save your word document and then upload on Moodle.
