Q01: What do you call the sum of n terms divided by n?
Q02: What represents the middle term in a sorted list?
Q03: What is the most common number in a list of numbers?
Q04: What do you call the difference between the highest and lowest values?
Q05: What is the smallest value in a dataset called?
Q06: What is the largest value in a dataset called?
Q07: What common name for the mean can also be used to refer to median or mode?
Q08: What do you call how values are spread across a dataset?
Q09: What distribution is symmetric and bell-shaped?
Q10: What distribution models a single trial with two possible outcomes?
Q11: What distribution models the number of successes in a fixed number of independent trials? Hint: Our fighter had n=4 trials and p=0.15.
Q12: What distribution models the number of trials until the first success? Hint: We expect our fighter will need 7 attacks before he hits once because the expected value is 1/.15 ; this is slightly less than 7.
Q13: What distribution models the number of events occurring in a fixed interval? Hint: it is defined by λ (average event rate). Hint: Behold the power of FISH!

Q20: What theorem states that the sampling distribution of the mean approaches a normal distribution as sample size increases?
Q21: What principle states that sample averages tend to approach the expected value as sample size increases?
Q22: What measure tells how many standard deviations a value is from the mean?

Q24: What procedure is used to evaluate a claim about a population parameter?
Q25: What probability helps determine the strength of evidence against a null hypothesis?
Q26: What do you call repeated experimental units set up under identical conditions?
Q27: What term describes differences in results among identical experimental trials?

Q45: What variables are kept constant during an experiment?
Q46: What term describes the probability of detecting a true effect?
Q47: What term describes the number of experimental units in a study?
