Lab 4 STA 2023: The purpose of this Lab is to allow you to apply some of the statistical tools we learned in the first three chapters to real world data sets.

You may work with others in the course or you may work individually. Each student must submit his or her own document in Canvas. If you work with other students on the assignment, you must acknowledge them on your submission.

We will be using the StatCrunch or Excel file dataset: Janssens Summer 2018 Intro Stats Lab 3.xlsx. You can find this dataset by going to StatCrunch , click on the Explore tab, then in the right hand search box type in “Janssens”. There is also a copy of the Excel spreadsheet containing the data posted with the assignment. (See the Powerpoint “Lab 1 Information” in Module 2 for a refresher on how to find the data and do analysis in StatCrunch )

Step 1: Original Submission 4 possible points

You must answer all of the following questions and must submit an online document in pdf format with the answers.

All questions must be answered in full sentences.

You can use any tool you wish to answer the questions; StatCrunch, Excel, your calculator where appropriate or any online stats tool that you are comfortable with.

Each student must make their own submission to the Canvas Assignment Lab. If you work with other students on the assignment, you must acknowledge them on your submission.

If you do not submit a document with all questions answered by the first due date, you will get no points for this Lab. Labs are worth 30% of your course grade.

Once you have submitted your answers to the original Canvas Assignment, post your answers in pdf format in your Group’s Files right away.

Step 2 Group Learning and Final Submission 1 possible point

You must view the submissions of the other students in your Group and in the Discussions section of your Group and make comments on at least one other student’s submission. Good comments ask questions, share learnings, suggest upgrades, and acknowledge strengths.

You can earn up to 1 point for this assignment by making substantive comments on your group members submissions. “Hey, that looks great” does not count as a substantive comment.

If you submit to your Group close (after 3pm on the due date for final submission) to the deadline then your comments won’t help your Group mates and there is no real chance for substantive dialogue so your submission will not get the point available for this part of the assignment.Easy questions
