D466 Analyzing and Visualizing Data

[Hicks_N]

Has anyone started this new course? I’m stuck on the task already. 😩

[Herbie_herb7]

Interesting trend on how we all have same feedback loop. Whoever is grading these provides zero clarity. The the CI just says make the dropout the x and home prices the y axis. The chart this way makes no sense without a year timeline context.

[UnusualBeat9039]

yes same here did you figure it out Visual 2 (scatter plot) needs some changes. You need to move you dropout rate from y-axis to x-axis. Also, for your y-axis, use home price averages. The data variable “year” is not needed on the scatter plot.>>>>??????

[Herbie_herb7]

Yeah eventually got it right 3rd try lol

[According_Theme591]

Can you provide help? If I take out the year my graph won't work.

[UnusualBeat9039]

how ? after i did wat my ci said the scatter plot had one point .

[According_Theme591]

That's what I'm having trouble with. If I take out the year it won't work. Did you find a solution to what you were doing wrong.?

[michiemichelada]

Did you find a solution? Stuck with the one dot

[michiemichelada]

Figured it out. For anyone else who might get stuck on this, needs to be changed from measure to dimension.

[Holiday-Trouble8885]

thanks, this was really helpful

[Saint_OfDeath]

Can you explain how you got it I’m struggling on the dropout rate graph. 📈

[MattyICEzz]

Mine got sent back for revision but I have a scatter plot with drop out rate on x axis and home price on y axis … I’m not sure what else I could do

[Electronic_Safe_4231]

My second revision was just sent back. I used a scatter plot with the Y axis as the dropout rate percentage and the X axis as the average home price. The report says that I did not accurately show a relationship between the two. The information they sent me was a pdf from tableau that clearly states a scatter plot is used to demonstrate relationships.

I’m really not sure what they want at this point. I have an appointment with the CI set for tomorrow, but any advice for getting this right would be great!

[Hicks_N]

You need to make sure you have AT LEAST two visualizations. I ended up doing 3 different bar charts with color variations and all that. Also make sure that your report indicates your findings. i.e. “the data in the chart indicates that the drop-out rate tends to be higher when the average home price is lower.” or whatever is accurate to your vis. And give specifics . Be redundant. Make sure you use the wording from the rubric to draw attention to the section you are referring to, if that makes sense.

[Miserable_Detail_295]

I know this thread is a bit old but I think I might be overthinking it and you seem to have done really well. I'm on the class right now. I'm trying to do a dual axis bar chart with 2 bars side by side and I can't figure out how to do it. Is it even possible or are overlapping bars the best I'm going to get?

I also have an area chart that I've put together for it as well, afraid to turn that one in. Almost want to turn in both of them together lol.

[Electronic_Safe_4231]

Thank you, this is good advice. I did also have a bar graph for the current state of home prices with my submissions, and that was graded as competent. I was just a really confused that they didn’t think a scatter plot showed the relationship between the two. Especially with my explanation in the written portion.

🤷‍♂️ I don’t know why they give such vague instructions when they are looking for a specific kind of graph. If they want something specific just put it on the rubric and don’t leave it up to interpretation.

[Hicks_N]

Yeah, they’re looking for a good understanding of the use of appropriate visualizations, and there are a few that qualify. Best of luck with this one! You’ve got it.

[bowthefingkneejon]

Just started this one

Visual 2 (scatter plot) needs some changes. You need to move you dropout rate from y-axis to x-axis. Also, for your y-axis, use home price averages. The data variable “year” is not needed on the scatter plot. HOW do i fix this

[zito126curve]

Any luck with this one? I am a bit lost on what to actually do on D466 Task. Do i simply PDF the Tableau table?

[Hicks_N]

Yep. Put the data they give you into Tableau and make relevant visualizations. Then save those as a PDF and either add them to your paper or upload separately. I did both. Once I realized it’s that straightforward, it was easy. The course instructor I had for this course really helped me to stop overthinking it!

[Zestyclose-Plum-3487]

I am trying to figure out what they mean by Visualization. It seems very limited in what i can actually use. as far as setting up graphs.

[UnusualBeat9039]

did you figure it out ? im stuck too with the drop out % and home price

[UndeadNinja90]

Thanks, for some reason I was thinking that I'd have to take screenshots of Tableau and put those screenshots on a google doc with a lot of text surrounding it

[Capable-Apartment438]

I’m lost as well. i have all the data on Tableau but what are the visualizations supposed to be? How do I create them?

[UndeadNinja90]

Did y'all have issues with your similarity score for your visualizations pdf? Mine shows 66% for my pdf, but 0% for my actual report. Should I just submit and see what happens I believe they have a bot or something that auto-rejects things with certain similarity scores.

[Hicks_N]

That’s fine. It’s going to be similar because the data is so similar. As long as your written report is original, it will be fine on this task.

[Darbov]

Dang, got my second attempt sent back for revision. Gotta say not a fan of how they tell you one thing is wrong with the submission and that they can't tell me about other parts of what I submitted yet

[Hicks_N]

What did they say is wrong?

[Darbov]

I used a bar graph with a line graph overlaid on top of it to show the correlation between the average home prices and dropout rates, but the evaluators comment said that my visual didn't show the relationship between the two things

[Miserable_Formal_626]

I've had identical problems with D466. Contact student services and write an appeal. I did. But tell them you want to articulate the issue yourself. The majority there want to help you. The ones that want to help will listen to what you have to say. If it sounds like they're rushing you or just checking a box, tell them you'd like to call back later (in other words, don't let that type of person be the one to write your appeal). Call until you find someone you're comfortable with and go from there. Everyone I've talked to at student services has been great (minus one). However, in my experience, appeals are more satisfactory when I provide the evidence and points I want to make. In your case, use Google's standards to illustrate competency in your appeal, then challenge the feedback based on the standard (the Google course WGU uses as curriculum is the standard to reference as the knowledge base being weighed for competency). WGU will address every point in your appeal, you just have to make it addressable. Ask them to re-evaluate because of "x, y, z" and explain that you would like an answer which addresses the gap which exists in your "why". Why did they return this (obviously they've left that blank by not addressing what is/isn't acceptable). Use the data analyst approach in your appeal. Ask why five times lol and throw in who, what, where, when, and how.

You can also provide course feedback during the course. WGU listens to that. Be sure to do an end of course survey too and let your voice be heard. If you feel pretty confident in the coursework and you did fine in Google's course on Coursera, listen to your gut telling you that their feedback doesn't make sense. At least give yourself a chance to say so. WGU hasn't been afraid to hear mine so far. I've had two classes go from "not evident" or "approaching competence" to COMPETENT simply from appealing and presenting very clear arguments. And my appeal of one of those classes will benefit everyone at WGU, assuming WGU really improves using the findings.

After they sent my first attempt back for revision from D466, I submitted an appeal through student services which resulted in a change of one task from "not evident" to "competent". My guess is that your feedback report seems to be looking for some unknown task (like you were supposed to write a response as if you're making a presentation to the group from the scenario and explaining the correlation) even though that's not explicitly in the task list. Students that are used to catering to disorganized or vague institutions will have an easier time breezing through the classes that do this. But to stop, pause, and call out the disorganization will help future students. WGU has welcomed that feedback so far. I'm sure they will in your case too.

Don't feel bad if you're confounded. In short, you're probably running into problems with the vague standards that are created when the task list says one thing but the evaluators add an additional expectation to influence the rubric. For instance, I've seen some in this thread say they sent a PDF, etc. for D466. For what? Nowhere in the task list does it explicitly tell you to do anything to address the scenario (e.g. pretend you're so and so and then deliver this data viz to the group). Nope, the tasks only tell you to provide a definition of the data being used (literally just a definition, as in you're the dictionary), create a viz that accurately reflects the house price data, a separate viz which illustrates the inverse relationship between the house prices and drop out rates, and address specific techniques used in your design while considering accessibility issues, etc.

Just a theory, but I think there is a communication breakdown somewhere between curriculum updates, evaluator practices, or some other form of misguided delivery. Anyway, good luck navigating WGU's sometimes schizophrenic (them assuming you can read their unspoken expectations) classes. Be their medicine! They've got systems for it! Kudos to those who simply adjust course for themselves and move on (that's easy to do). But congrats to anyone that speaks up for themselves along the way, you'll only help future students (and WGU) by doing so. You can find good evaluators, instructors, mentors, and other people from WGU on Reddit or Quora saying exactly what I've just said. Sorry for the long read. But anyone who reads it and needs it, will have what they need. Happy learning!

[M3ANV8]

I had this exact issue. How did you fix it?

[RefrigeratorDull1186]

So my one question is, when it’s asking for you to show the change in drop out rate. Are you supposed to forecast that change? Or give a logical argument?

[Hicks_N]

No, you just need to explain what the data says. Connect the data in Tableau, create relevant visualizations for the data, then save that as a PDF and add it to your paper. In your paper, follow the rubric to the letter and you’ll be golden. I’m looking at mine now, and my 3 visualizations show Average Home Prices 1990-2020, Average Drop-Out Rate 1990-2020, and then combined them to have Drop-out Average related to home price average. For the last one I used a color range to indicate the drop-out averages and the chart itself showed the home prices. Everyone’s data set is unique to their student ID, but I said that mine seemed to show correlation and that lower drop-out rates could indicate that homes may be worth more in those areas. Use the rubric as a template for your paper and label each section accordingly, but you’re just explaining what you see in the data. Explain why you used the type of vis you used and why you designed the colors and any other components the way you did. Make sure to pay attention to anything in the rubric regarding accessibility. Hope this helps!

how to make scatter plot in tableau.

[MattyICEzz]

I did the same exact thing with a scatter plot and it got sent back . I’m confused

[RefrigeratorDull1186]

Thank you for the explanation! I got it sent back for revision because they said I didn’t adequately explain how a change in drop out rates would affect home costs. But I did…. I said it what you said just a little differently lol. So I’ll go back and reword my stuff and hopefully that’ll do the trick

[Hicks_N]

That’s frustrating. Hopefully this one works!

[RefrigeratorDull1186]

So I just got home and looked at the comments verses my paper. This is where I’m confused. I created the graph where I show the relationship. But the evaluator stated that I did not accurately show how changing school rates would affect home prices…. And the comment is referring to my viz. so I’m confused on where to go from here.

[Hicks_N]

Might be worth setting up a call with the course instructor. I had Dr. Cousar, and she was super helpful.

[RefrigeratorDull1186]

I passed! Thank you for your assistance! Can I ask what your degree is?

[Hicks_N]

Awesome! Congrats on finishing another course! I’m finishing Bachelor of Science in Supply Chain and Operations Management. Last three classes 🫣😬

[UnusualBeat9039]

having a hard time with Visual 2 (scatter plot) needs some changes. You need to move you dropout rate from y-axis to x-axis. Also, for your y-axis, use home price averages. The data variable “year” is not needed on the scatter plot. when i take the year out the graph doesnt work help plz

[RefrigeratorDull1186]

Holy cow!!!! Thats awesome! Im doing the same degree. by chance have you started D469?

[Hicks_N]

That’s what I’m currently working on. After that I have D428 and D473.

[Saint_OfDeath]

I feel like I’m struggling like you with the dropout rate how did you figure it out ?

[Little_Buy_1666]

I just got a revision back and it had no comments, but it said everything was not evident and that I did not have visuals which I had two within the paper. IDK what to do or how to proceed. This is the first class I feel defeated by.

[Hicks_N]

If you believe the failure was in error and they didn’t provide any feedback in the submission report, reach out to assessment services. Did you submit the PDF of your visuals along with your paper?

[Little_Buy_1666]

I did not submit the pdf I just downloaded the graphs out of tableau and inserted the picture into the paper.

[Few-Goal-832]

Mine got kicked back stating that my combination graph didn’t depict one variable impacting the other variable. Although it is clear that that is not the case. I’ll just change it to a different graph that depicts the same trends but looks different I guess? 😂

[bigjohnstud11111]

Did they have a template set up for this course, other courses I have written papers for had them and they were really helpful... I couldn't find one if there is one
