Assignment: ANALYZING AND VISUALING DATA
Background: This assignment focuses on data analysis using the tally() function. You must be able to analyze data before you try to present data through visualizations.
Task
• Use RStudio and R Markdown to generate a Word document with the R commands and answers to all of the data analysis questions listed below.
• Follow the formatting requirements identified in the Install R Markdown video.
• Follow the data analysis instructions provided in the videos this week.
• Use the appropriate dataset for each question. All required datasets are available on Blackboard at the bottom of this week.
• Use the tally() function to produce the correct answer for each of the questions listed below.
• Carefully choose the correct field operators and logical operators when writing the tally() function.
• In your final Word document, circle the correct answer for each question when the results of the tally() function create a table rather than a single answer. Failure to circle the correct answer will result in zero points for that question.
