I literally suck at those two since I have never taken stats in my life before. Am I f*** for the qr section?

Check out youtube for some of them. The 99/95/68 % rule is very easy to learn.
Did you watch Chad's probabilities? The dice, cards and marbles aren't too bad...sometimes you don't even have to do a calculation, just think about it.
I never learned Permutations but Chad did help me with that....I did have to watch him twice though.

The 99/95/66 % rule is very easy to learn.

I thought it was the 99/95/68% rule.

What it means is that in a population of say 100 students with a mean test score of 70 and a standard deviation of 7....

The mean will be 70.

68% will be within 1 standard deviation away from the mean (68% of the students will have a score between 63-77).

95% will be within 2 standard deviations away from the mean (95% of the students will have a score between 56-84)

99% will be within 3 standard deviations away from the mean (99% of the students will have a score between 49-91).

I took the DAT today and had 2 probability and 1 statistic question. Wish i spent more time preparing for them so I HIGHLY recommend as much practice with them with Math Destroyer.

Needless to say those were the easy questions on QR....
trust me lol every question counts on QR, bc the story problems can be very tricky
