IT 223 -- Project 1

Practice using R

Open a Word (.docx) file. Add your name, submission date, and project number at beginning of the output file, for example:

Stan Smith
Project 1
Jan 15, 2026

For each question of this project, include (1) the R source code that you used, (2) the R output, (3) the written answer to the question.

1. Create a vector of these hypothetical exam scores from the R console using the c (combine) function:
   
   • 98  93  85  39  91  75  5  93  79  90
2. Print the dataset.
3. Compute, Q0, Q1, Q2, Q3, Q4, and IQR for the hypothetical exam scores. In addition to including your R source code and output, type this information into your Word file like this:
   

   Q0: ???
   Q1: ???
   Q2: ???
   Q3: ???
   Q4: ???
   IQR: ???
   

   This shows that you can find the requested information from the R output. Type the actual values of the quartiles read from the R output instead of ???.
4. Create the histogram of the hypothetical exam scores. Click on the resulting histogram window. Then right click in the histogram graph, select Copy as Bitmap... to copy the graph to the clipboard. Then paste this graph at the end of your Word document.
5. Create the boxplot of the hypothetical exam scores:
   

   Answer:
   > boxplot(exam_scores)
   

   Save the boxplot graph at the end of your Word file like you saved the histogram.
6. Save your output file as proj1Smith.docx. (Replace Smith by your last name.)
7. Submit your Word file to the Project 1 dropbox on D2L.
