Video clip: showing how long the video length is so a student can see how "short" it actually is, since Cam does not state the length in her message.

typo on the round 1 objective page.

For example, you might come across different types of data in the web data than you will(missing word?) in the sales data, and you’ll have to adjust your transformations accordingly.

Your questions are not near specific enough, and most of them are errant to begin with. You give a survey that does not ask about importance of attribute, yet you ask a question that is "which attribute is most important to the target cluster". This is not proper analyses.

In this one question it states "Identify the cluster with the highest average income. What is the average frequency of online backpack purchases?" This is an grammatical error. You are asking two questions and it is therefore unclear. You ask "Identify the highest average income cluster", and THEN ask "What is the average frequency of online backpack purchases". This is confusing. Do you want just the average frequency of online backpack purchases in general? Be more specific.

I have been spending way to much time on trying to figure out when I am complete and going through each step. I finished this cluster analysis but it won't let me continue to next cluster analysis I don't know where else to look to move on.

But how should we deal with what we remove? Leave it blank? Replace with null? Replace with average? What? My inclination is leave it blank, but . . .

Some students may prefer a soft or hard copy to work through using the spreadsheet information to answer the questions.

It was giving a percentage of how well the data was cleaned but no feedback of what they did wrong. Since there were no teaching notes and I couldn't see their submissions, I couldn't give them feedback either.

If students change the smallest detail, then the files will no longer work.

Sometimes data wouldn't upload or a student would upload a file and then when she tried to download it the downloaded file didn't match what she uploaded.

I didn't work on R2 at all, how come I jump into R3?

The results of my work for R1 has been removed to I am off to start terrible on R2

The score is not readily apparent on the Data Transformation report. Fixable and fixed rows are color coded and make sense but the format suggests there will be a black bar for score but you just need to look at the bottom.

Videos should have a transcript for ADA.

On the intro page there are two sections under the intro video, but it isn't clear what they are. At first I thought they were just the text version of the video and ignored it. But then I noticed they didn't follow the video but still weren't mentioned. If these two items aren't tied to the video, I wouldn't keep them on the same page. I think most students will ignore them.

Organize Excel tutorials - it's hard to know which one will teach me what I am trying to learn and I'd rather not look at them all unless I know I need to.
It would also be nice to have Excel tutorials next to the tasks we have to complete. Maybe students in this class will already know how to do what we are asking, but it would be nice to have a tutorial or 2 next to each task in the first round to get comfortable.

There really isn't a clear way of knowing what decisions have been completed.
