Started: Feb 13 at 12:21pm Quiz Instructions This assignment will be self-graded. You first do the work given in the Word file, and then you will take a Quiz on your result. This may be new for you, so for the first one I will give you two chances for the first one (but only the first one). The focus of this assignment is on types of variables; and the Stem and Leaf and Box Plots; and measures of central tendency. Don't start this assignment until you are ready. First you will work with the data in a Word file (you can move it to Excel) and do some analysis. Then you will be ready to answer the questions. We will give a generous amount of time to complete it - 3 hours - but you can't leave it open forever. And once you open it, you must finish it. I will allow two chances for the first assignment so you can get used to this format. This is only for the first assignment. The file for this assignment is below, along with a Excel file for an optional problem. STAT 200 ASS1 2023.docx (https://udel.instructure.com/courses/1766087/files/131101409?wrap=1) This file is an example for the Optional problem. Rank of Thomas.xlsx (https://udel.instructure.com/courses/1766087/files/131101315/download?wrap=1) (https://udel.instructure.com/courses/1766087/files/131101315/download?download_frd=1) I will arrange that your answers will be shown to you by the time the exam is open , but not before then. That is because students tend to share answers too easily. The Excel file might be useful: Basic STATS.xlsx (https://udel.instructure.com/courses/1766087/files/131101455?wrap=1) (https://udel.instructure.com/courses/1766087/files/131101455/download?download_frd=1) 0.1 pts Question 1
