The easiest way to weight your class's final scores is to access the Grade Center and then you will see a column that's titled Weighted Total. It's a default column. Blackboard automatically creates this when it creates the Grade Center. What you are going to do is click on the button with the two downward facing chevrons to the right of Weighted Total and choose Edit Column Information. Now so far we've got four quizzes, four term papers, a Midterm, a Final and Class Participation. Let's do a normal distribution.
We are going to say the quizzes are worth 25%, term papers worth 25%, midterm's worth 15%, final's 25% and participation is worth 10%. For this to work all of the columns have to exist now. You can't go and weight your grades now and then come and add new columns later. You have to set up the columns, they have to exist, then you can go and weight them. So if you haven't done that, stop, go back, create the columns. Once the columns exist you can scroll down and in this case, we need to choose which columns we want to grade.
Remember earlier we actually created some categories, so we actually have a Classroom Participation category. We have an Assignment category, which are those term papers. Now this is where things get a little confusing. We do have a Test category, but you remember in the last movie we actually created a new score column, where we took the four quizzes and drop the lowest one score. If we want that to count, we are not going to do the category. We have to choose the particular column here.
So I am going to choose the CUMQUIZ. Remember, if you already dropped scores don't use the individual columns. Use the new total column. We've also got a Midterm and a Final. I didn't actually categorize those, so I will click on the Midterm first, pull that over, and I am going to choose my Final. And this should get everything. I mean we've basically now have our ouizzes, our Midterm, our Final, our Assignments, I am going to scroll down a little further, and I have got my Classroom Participation.
So as I said our idea was that our quizzes were going to be worth 25%. That's pretty simple. We just type in 25%. Down in the bottom corner it says Total Weight 25%. Your Total Weight at the end of this has to equal 100%. Next thing we have to do is we are going to do the Midterm. Remember we said the Midterm was going to be worth 15%. We said that the Final was going to be worth 25%, so far so good.
Now we've got the Assignment and notice that with the Assignment we have multiple columns and in fact, we are going to be pulling in four term papers, Not only do we have to figure out what percentage the term papers are going to be worth-- in this case, it's going to be worth 25%-- then we have to decide, well how are we going to weight that? Do we want to weight it equally, do we want to do it proportionally? We can drop the grades here if we want to. Remember we haven't actually dropped any assignment grades. I could do that.
But in this case, all of the assignments are going to weighted equally. I could do Proportionally, in which case I have to choose by the total points possible. In this case Equally is fine, and then finally we have got 90% so far. Classroom Participation is worth 10%. So what I did was I basically chose the columns that are going to count towards my weighted score, my final weighted score. Is this going to Calculate as Running Total? In other words, if a score is blank is it ignored or is it counted as a zero? Ignored I say yes. No means zero, and I like No.
I am going to scroll down and click on Submit. So I am going to scroll over and my Weighted Total in this case is 20.83%. Why is the student's grade so low? And the answer is because we decided that we set the Running Total to No, meaning that because the student has not taken the final the student has a zero on the final. Because the student has not taken a midterm, the student has a zero on the midterm.
That's why the students failing in the class right now. But as I start entering grades for the student, in our term paper and we will just start entering. We will give the student 90s on everything. And now Jay has a B in my class. But wait a minute, a B? You gave him 90s in the hundreds, we dropped lowest Quiz score. Why is it a B? Aha! Notice that the Class Participation is still empty. I haven't given him a grade for Class Participation yet. That's 10% of his grade. I go in here and it turns out this is worth a hundred points and gave him a hundred points.
Then he finally gets the A that he deserved in my class. So what's the difference between the Weighted Total and the Total column? The Total column is just the arithmetic mean. It's basically adding up all the scores, all the raw scores, and dividing them by the points possible. That's not what's happening in the Weighted Total. The Weighted Total is actually- it's a pretty complex algebra. So if the numbers aren't the same, it's because we've added different weights in different areas. So remember, the easiest way to weight your class's final scores is to access the Grade Center, click the Weighted Total column, click the button to the right of the Weighted Total column and choose Edit Column Information, and then enter the columns and the percentages that you want to include.
