More descriptive statistics (at least, median and mean) for every column in "Grades" (gradebook)

More descriptive statistics (at least, median and mean) for every column in "Grades" (gradebook)

(5)

One can see the mean for individual assignments in "Grades" (gradebook) but the median is not provided. Would like to see that as it is a crucial measure of central tendency in performance. For columns in the gradebook, that are an average of category assignments and an average for the course ("Total"), no descriptive statistics are provided at all. I would, at the very least, want mean and median provided, but, like for individual assignments, I'd like a graph of distribution of marks too. Thanks.

P.S. I'm aware of the boxplots in Course Analytics.

Thank you. I really do try hard to search for similar posts in "Ideas" before creating a new one. Somehow, my search terms did not obtain these "light bulb" links in results. Also, I know I can export to Excel and generate the stats, but it's obviously more seamless to have them right there. Wondering why the choice to stick only with mean for individual assignments when median is additionally informative, as it's not affected by extreme, low scores.

I also think basic statistics: mean, median, mode, Min. and Max is necessary information for both students and instructors. The mode is actually the most useful statistic as it represents the most common score. The average is skewed of course by very high or very low scores. Since we are in the business of education and statistics help instructors evaluate the assessments used to assess student progress and also improve a course, complete statistics should be standard in a course management system and not something that should be requested or voted on.

This idea has moved to the next stage and will be open for voting among the Canvas Community, from Wed. October 5, 2016 - Wed. January 4, 2017.

Check out this doc for additional details about how the voting process works!

I have a problem with Canvas reporting the min and max grades to students. The quartiles, median, and mean are fine, but I think it is not the students' business what the lowest score was. I am less concerned about the highest score. The problem is that the class may have a very good idea who got the lowest grade in the class, and with that knowledge, now they know that person's grade too. That's a FERPA violation. I don't think any individual scores should be visible to all the students. The min and max are very likely individual scores and may be tied to an individual with only a little extra information.

I found the option that allows me to turn off the stats for the course, but I would like the students to see the rest of the stats, just not the minimum score in the class.

You are making some assumptions with your statements.  Individual scores are never available to all students at our University. Students can only see their own scores. You are incorrect that the min and max are tied to individual students. There can be more than one person with the min grade and more than one student with the max grade. Reporting the min and max does not in any way violate FERPA.  If you have a class of 200 to 1000 students, the only person who knows who had what score is the student themself and the instructor. Canvas is used in many settings...not just tiny classrooms where every student might know every other student. The best option is to have the ability for canvas to calculate all stats and give the ability to the instructor to report what is appropriate for their setting.

Being able to add the basic statistics:  Mean, Median, Mode, Min, Max and SD is highly requested by our faculty. They also want the ability to turn it on and off in the column itself to show or not show to the students in general.  Even just to see for themselves would be sufficient.

Instructors also need statistics to adequately gather data for GENED assessment.

How can any serious gradebook web app not generate a histogram and statistics for a graded assignment?

This is a major flaw of canvas. In addition to each column, we need to be able to assess basic stats for the cumulative grade at any given time point during teaching. It is important to see the grade based on all assignments graded for the cohort, NOT just for an individual student.

One reason that it can be useful to display a wider range of statistics to students is that there's often at least one student who fails to complete the assignment and earns a zero. The zeros lower the median grade and give a distorted impression of how difficult the assignments are and where students stand in relation to their classmates.

May I inquire into the progress on this? The "Radar" category is not very specific in that regard. Having to constantly export to Excel, instead of a simple point-and-click on "statistics" option, is getting a bit tiring. Thank you.

I'd like to make sure that we are including grade distribution in this enhancement request, meaning number or percentage of students who earned 90 - 100%, 80 - 89%, etc., for manually entered scores. 

I understand that this information is sort of provided in the quiz analytics for quizzes created in Canvas, though I have issues with how difficult it is to decipher that information too.*

This is such a basic feature of any grade book system that I'm still trying to wrap my head around the fact that it does not exist for all columns in the Canvas grade book.

*Should the Canvas developers consider modeling these statistics after those available in the Quiz Statistics ... I personally find those graphics hard to read. Translating the bar graph to a student count requires that I hold a piece of paper horizontally on my monitor and line it up with the top of the 90% bar to get an accurate count of how many students earned in the 90% range. That raw number should be directly on the graph or available by hovering my mouse

over the bar.

Hello -- is there any update on this?  It's been more than a year now, and the median specifically is a feature that should be incorporated into the gradebook.  Boxplots by definition are supposed to show the median (as opposed to the mean which Canvas currently shows), so incorporating the median would help improve that feature as well.

Being able to view histogram charts for any assignment, not just a quiz, is also critical for our faculty. Is there any update on this feature idea?

Please add assignment statistics to the new gradebook, including these additional statistics options.  Right now, the new gradebook does not offer any assignment statistics.

The Radar idea stage has been removed from the Feature Idea Process.  You can read more about why in the blog post Adaptation: Feature Idea Process Changes.

 

This change will only impact the stage sort of this idea and will not change how it is voted on or how it is considered during prioritization activities.  This change will streamline the list of ideas 'open for voting', making it easier for you to see the true top voted ideas in one sort, here.

I'm going to reiterate that this is a necessary feature in the New Gradebook. For those who haven't realized/are not yet using the New Gradebook, we losts the in-column stats. Theses were replaced with the Course Analytics page, but mean, perhaps the most-used data piece, is missing.  @kpasch  mentioned this a few weeks ago and was told to come here. I think there's something to be said for data showing up in the gradebook itself, including course average, individual assignment averages, and section averages, but I'd be fine with it being on the Course Analytics page as long as the average were included. Canvas knows the numbers and should be able to calculate that information. I just spoke with a teacher in my school who's a new Canvas convert, but she's feeling rather disenchanted by having to manually calculate assignment averages. If I'm going to keep convincing people at my school to use Canvas for grades, the gradebook needs to provide them with tools they are accustomed to having.

Update/note: The median is an option on the Course Analytics page, along with the high and low scores. When I already have nearly 100 assignments six weeks into school, though, this page starts to get overwhelming.

Update 12/2/19: My district has now enabled "New Analytics." Mean is, in fact, an option here, but it still seems more cumbersome that just including it in the gradebook to begin with. Plus, even once I've updated the grades, they can be slow to transfer to the analytics page.

There is an explanation that the removal (for now?) of median from New Analytics was a deliberate decision, along with hopeful news that section mean may be added:

I wish to add emphasis on getting access to any scored item in the Grades as a histogram with other analytics; immediately after grades are entered.  I post an announcement notifying students that an activity has been scored immediately after I complete the grading process.  I have always included a histogram of the scores in this announcement.  This is available in the New Analytics, in a roundabout way--but the refresh can be delayed 24 hours.  The instructor seems to have no control over when the refresh occurs.  There should be a button to refresh the data for the analytics immediately so instructors can see the data graphically immediately after competing grading/scoring.  The current workaround is copying the data to Excel and creating a histogram manually--doable, but there has to be a better (more efficient) way.
