5th box -Flashcards

The last two digits are divisible by 4.

The "tail" of low-frequency values points in the positive direction, and toward the hill is negative. The mean is more than the median.

The resulting equation is inversely proportional (not proportional, like a baking recipe). So, set up a proportional equation and then flip one of the sides. It is important to use the same units on each side! 15/9 = 21/x -> 15/9 = x/21 -> x=35.

The 15th percentile is greater than the average of the 10th and 40th because the tail points in the negative direction.
