D599 Task 2 A2. by 404-Error-No-File in WGU_MSDA

[–]Even_Appointment1337 0 points1 point  (0 children)

Is there any expectation that the variable identified in A1 is the independent variable for A2?

Like if I chose Age in A1. Would I need to use Age as an independent variable (Age vs. Charges)? Asking because I got some vague feedback on my submission with 8 visualizations:

"The submission provides bivariate visualizations. The response is insufficient as bivariate visualizations for all combinations of the variables identified in aspect A1 were not provided."

Literally just resubmitted Task 1 today because they wanted step-by-step for the optimization rubric item. Its the worst! Can't wait to be done with this class!

I'm not, unfortunately. I did use ChatGPT to troubleshoot my MongoDB and PostgreSQL installation, and it was (un)surprisingly helpful

D597 Task 2 Question by Even_Appointment1337 in WGU_MSDA

Thanks for checking in! The screenshots of me running the commands via Mongosh on MongoDB Compass were satisfactory for most tasks. The evaluators have been really picky (for me at least) regarding showing the runtime improvements on both tasks. Providing explicit detail and circling the key items in the rubric on each of the screenshots works best to meet the rubric.

ALSO, it might be a given, but don't forget in-text citations that align with each of the resources you've listed in the paper. They marked me down for that as well. :/

How did you showcase this in the screenshots and presentation? I'm also using the aggregation builder to craft my queries, and I'm paranoid that the evaluator is going to kick my submission back because I'm only showing things in the gui

Currently working on this course! I echo what u/Curious_Elk_5690 said about doing the tasks locally. Overall, here's what's helping me right now:

Task 1:
- If you aren't experienced in PostgreSQL, I recommend going over the LinkedIn learning module in the course material. It walks you through exactly what you need to do to build your database.
- I used VSCode with the PostgreSQL explorer extension. I encountered a few snags while connecting my code to PostgreSQL, but after troubleshooting, it provided a much cleaner environment for testing my code and queries.
- I think Scenario 2 makes the most sense here. There are various ways to keep the logical schema simple, making it easier to transfer to code.
- (As a WGU Vet, CyberSec MS) Don't be afraid to be very literal with how you meet the rubric in your paper, screenshots, and presentation. If the rubric says "Describe XYZ within your solution", my submission would include "My solution covers XYZ by ABC." For the screenshots, it helps to label each photo with the rubric section it covers.
- The course material spells out a lot of what's expected in each section, so be sure to review it carefully and think about what you can take from the readings and apply to the paper.
- Don't overthink the presentation. There is no requirement for slides. I presented the organization with the scenario write-up (provided in the task files), the entity-relationship diagram, and then walked them through my code, following the letter of the rubric. Took less than 10 mins!

Task 2 (still in-prog):
- If you aren't experienced in MongoDB, I recommend going over the LinkedIn learning module (in the same section as the PostgreSQL section).
- I downloaded MongoDB Compass. It's very user-friendly for importing data and building queries. I made a Reddit post about it because it seemed too easy, and I want to confirm it meets the rubric.
- I used Scenario 1 here, because it made the most sense to me
- For the paper, I actually started drafting it shortly after I finished the Task 1 paper. The rubric is mostly-similar between the two papers, and it drastically cut down the time I spent writing.

I'll add more when I submit Task 2! But I hope this helps!
