Could you pass eighth grade math?

mean = average of the numbers in a set.
Median = the middle value of the numbers in a set


ALL three are types of average:

Mean is Sum of the set divided by the number of values in the set

Median is "the middle value of the numbers in a set" when the set is ranked in order

Mode is Most Often occuring number

This seems like it would be very challenging for the typical 8th grader in the United States today. In fact, I doubt many k12 seniors could get past that either, but I grew up in California too.




I tutor eighth graders in math, and this could be straight out of one of their textbooks.

Might be a different story for me......

They had 12th grade math? :$

My last year of math was 10th grade, I finished Algebra 3/4 (Trig?) That was all the credits I needed because I was smart and stuff. I wish I would have continued, I love math, but the teacher was a real drag. Thats the real reason I stopped. I didnt get her teaching style and she was a super-bitch :( Maybe I should go back to college?

I got 10/10 on this little quiz.

10/10.

But as a scientist, I use math for a living.:P

and yes, when you're a scientist, you often DO have to solve for "x"!;)



Yes, that's all well and good, but how often do you actually use the mode of a set?

Also, if "x" has an analytical solution, the problem isn't difficult enough. :D

10/10 but math is my fav :)



Me too! ::giggles:: If they'd just called it "finding the volume of jello in a bowl but cutting the slices reeeally thin and measuring each one" I think more people would like calculus. :D

Got them all, but the two about terms aren't really math but vocabulary. (what's a 'integer', what's 'whole number', etc, what is a 'mode', etc). Math is best thought about in terms of pure calcualting concepts, not definitions. (i.e., I've never seen much value in asking what the 'mode' of a sample was versus just asking which one occurred the most often.....scientists and mathematicians are always creating their own language for very simple things - job security)

I was hoping to see a question about cutting down trees in the forest and asking how I 'felt' about it. This was very heartening to see math instead of sociology.

I'm not cynical - you are.
