Ok, so I was figuring out my grade for my college class, 50 percent of my grade is homework and the other 50 percent is tests.
When I added all of my grades together and divided by 13(the number of tests and homeworks), I got a 78 which is a BC, aka what I need to pass.
When he averaged the test grade, averages the homework grade and then divided by 2, he got a 76, which is a huge difference. Can anybody explain why doing it that way makes any difference? They are both worth the same amount of points so I thought they should average out the same.
I'm very stressed out right now, I emailed my teacher, waiting for his response, hopefully he gives me mercy.
The number of tests and homework assignments isn't the same, that's what's changing things.
Simpler example:
Test marks: 60, 80
Homework marks: 70, 80, 90
The average mark on the tests is 70
The average on the homework is 80
If you average both of them (the right way to do it in this situation), the final mark is 75
If you just average everything, the final mark is 76.
tl:dr = he's right, you're wrong.
I never said he was wrong. The way he does it, that's my grade. I just want to know why :(. I mean it shouldn't make a difference if everything is worth the same.
