16: Causes Trump Statistics


correct answer is 41% : Applying Bayes’s rule in odds form, the prior odds
are the odds for the Blue cab from the base rate, and the likelihood ratio is
the ratio of the probability of the witness saying the cab is Blue if it is Blue,
divided by the probability of the witness saying the cab is Blue if it is
Green: posterior odds = (.15/.85) × (.80/.20) = .706. The odds are the ratio
of the probability that the cab is Blue, divided by the probability that the cab
is Green. To obtain the probability that the cab is Blue, we compute:
Probability (Blue) = .706/1. 706 = .41. The probability that the cab is Blue
is 41%.

standard scores: Researchers transform each original score into a
standard score by subtracting the mean and dividing the result by the
standard deviation. Standard scores have a mean of zero and a standard
deviation of 1, can be compared across variables (especially when the
statistica {he deviatiol distributions of the original scores are similar), and
have many desirable mathematical properties, which Galton had to work
out to understand the nature of correlation and regression.
