Description

The Category and Course totals in the ouuser display will not display as 'real' - percentage is shown instead.

In the attached all the item grades (10, 10, 2, 6, 2) are satisfactorily shown as 'real' but the averages, although set to display as real, are shown as percentages (but without the '%' symbol).

Category and Course totals do display satisfactorily as percentages and as letters.

Phil, can you be more explicit about what you want here? I think the original spec actually had percentages specified always.

Nick, can you follow up and fix any errors here?

I agree that we specified percentages - and that is definitely what we should export - and percentage works. So far so good.

But I find that 'letter' also works fine too. See fig.2. And I've begun to see the benefits of letter as some of our courses are just pass or fail (we will still want to export percentage).

So of the three settings that leaves 'real' and it seems to me that fixing 'real' to work is probably easier than trying to explain why two out of three settings work but the third one doesn't.

I'm gradually working through my documents and can now add that this is wider than the OUUser report - sorry I didn't point this out earlier.

In the Grader report if the Category total and the Course total are set to display as 'real' - percentage is shown instead.

So it's probably that the OUUSER report is reflecting this lower level problem. Figure 3 has the display of all items as 'real', and the numbers shown are correct. And the display of the Category total and Course total has also been set to 'real' but percentage is shown.

I am assuming (never assume!) that the average for the display of 'real' is calculated as follows (see fig 3. for example) but maybe I'm assuming incorrectly - let me know.
Under 'summative' there are three scores in the range 0-5. John Smith scores 5 in each. So the Average column would be marked in the range 0-5 and John Smith's average is 5.

But the 'formative' numbers are trickier; we have two marked in the range 0-100 and one marked in the range 0-10. What do we understand by 'average' here when displayed as 'real'. Is it in a range from 0-70 (i.e.(100+100+10)/3) and John Smith averages 66.67 (90+100+10)/3? This is what I'm assuming 'real' means but maybe I've missed the point.

I can see that the 'Course average' then becomes a very tricky number and maybe you are not wanting to get into such seemingly odd maths.

I'd better say that I don't see the OU using this display but I think we all need to be clear what 'real' means for the averages before we move on.

Hi, I think the reason why they appear as percentages is because column averages are set to 0 - 100 by default. If you have 2 grade items in a category, and scores are like 7/10, 16/20 then the aggregated grade would be 75/100 in the aggregated category total. If you do not want a default aggregation you can set your own strategy, and your own grademax for the grade category, but default is 100 so that's why the 'real' grade looks like a percentage.

Confirming what Yu said: A score that extends from 0-100 but doesn't have the percentage sign is simply a score in a range of 0-100. There has to be a default range set up for aggregated columns, because they may aggregate items that have different ranges. 0-100 makes the most sense, but it can be changed.

Thanks both for your explanations. I now understand things much better and am quite content with the general idea. However the fix that I downloaded today 8th October 2007 for the OUUSER view has removed the option of displaying letters ... which I quite liked! It may be that the version we had two days ago gave me everything I wanted ... but I just didn't know how to get it.

Can we put back the letter and real views into OUUSER? (I'm not sure that you meant to remove them). To illustrate
Screen shot 4 shows the Course Staff view. Everything is showing as letters.
Screen shot 5 shows the normal user view. And shows letters.
Screen shot 6 shows the OU user view ... no letters.

In setting up this message I've just found that if I'm logged in as Admin and view the OUUSER report from the drop down menu below Grader report then I do see the averages as letters. Don't know if that helps.
