PRAXIS II, what are the odds?
So the praxis and the completion of the math block are the things keeping me from student teaching right now. I just got done taking the praxis ii about 15 min ago and figured I would grab a delicious beverage and figure out what are the odds of me passing.
There are 50 questions on the the praxis ii, and you are given 2 hours to complete them.
I just picked my favorite letter (c of course) on about 15% of them. I figure that I will get about 1 in 4 of those right, there are only 4 possible answers after all. So 50 * .15 * (1/4) = 1.875 points
This means that I answered 85% with some work involved. Historically I am a B student, which means that I would get about 85% of the answers I worked through. However, because this is a standardized test, I may need to skew these number a little. The average score on the math portion of the ACT is 21/34 or about 62%, and we’ll call that a c. So, lets make the new b somewhere in the middle, like (85+62)%/2 = 73.5% This means that I collected 50 * .85 * .735 = 31.2375 points.
Well, as luck would have it, I still have a 1/4 chance of getting the points right that I may have done the math incorrectly for, so 50 * .85 * (1 – .735) * (1/4) = 2.8156
Lets add this up. 1.875 + 31.2375 + 2.8156 = 35.9281 so I may just get 36/50 or a 72%. I think that’s passing. Wish me luck everyone!
