◉ Empiracal Rule. Answer: if a variable is normally distributed the
following will apply:
-approx. 68% of data falls within 1 standard deviation of the mean
-approx. 95% of data falls within 2 standard deviations of the mean
-approx. 99.7% of data falls within 3 standard deviations of the
mean
◉ Average Standard deviation chart is how many deviations wide?.
Answer: 6 standard deviations
, ◉ standard score. Answer: the number of standard deviations above
or below the mean at which an observation is located
◉ standard score formula. Answer: SS = (observation - mean) /
standard deviation
◉ Z - score. Answer: Standard score
◉ z - scores follow.... Answer: standard normal distribution
◉ standard normal distribution is.... Answer: the normal distribution
that has mean=0 and standard deviation=1
◉ probability. Answer: a number between 0 and 1 that describes the
proportion of times the outcome will occur in a very long series of
repetitions
◉ Theoretical probabilities. Answer: how many times it should
happen
◉ experimental/ empiracle. Answer: how many times it did happen
◉ subjective/personal probabilites. Answer: how many times you
believe it will happen
