Rubric Score

Criteria 1: Presentation / Analysis Document

• Score Level: 4/4
• Comment(s):

In your presentation, you included...

• Document in PDF format
• Data observations slides using matplotlib plots
• Slide for hypothesis testing and results
• Recommendation

Criteria 2: Code Accuracy

• Score Level: 2/4
• Comment(s):

You have a few minor mistakes in your code...

• Please use boolean True/False instead of string 'true'/'false'
• For category_counts, think about when .nunique() and .count() return different results
• Your contingency tables are incorrect because your category_counts is incorrect

Criteria 3: Understanding hypothesis testing and interpreting the p-value

• Score Level: 2/4
• Comment(s):

In your presentation, you did...

• Run hypothesis testing and state the results
• Interpret the hypothesis outcome and connect to the objective of the analysis

You still need to...

• State the hypothesis
• Based on the results accept/reject the hypothesis

Criteria 4: Ability to interpret the Objective & Outcome of the analysis in a business context

• Score Level: 4/4

• Comment(s):

• Objective clearly states the business reason for the analysis

• Findings are interpreted accurately and are summarized in Recommendation / Conclusion. It addresses the questions raised in the objective of the analysis

Overall Score: 12/16

You did a great job on your code, and once you correct the few minor issues I mentioned, you should be all set.

You also made a great starting attempt on your presentation. Here are a few recommendations for you to improve your presentation.

• There are multiple business problems being addressed in this project. Make sure you clearly state the objective and recommendations for each one.
• For communicating hypothesis tests, try this framework: (1) state the null and alternative hypotheses, (2) calculate/display test-statistic and p-value, (3) reject or fail to reject the null hypothesis based on your p-value or test-statistic at your chosen significance level, and (4) explain (in business context) the conclusions/recommendations you made based on the hypothesis tests.

You made great progress on this project, so keep up the good work and resubmit.

hello Good day!, I would like to follow up if you already received my re-submission?.. I have resubmitted the updates 3 days ago. Thanks

[albemlee]

I apologize that it took so long for a response.

Your resubmission looks much better, and your contingency tables are now correct. I also liked the new slides you added to your presentation that better describe your hypothesis testing. Good job!

[victour03]

Thank you very much so all good now?

[albemlee]

You should be all set.

[victour03]
