PUBH 101 exam 2
mean - ANS-the sum of values in a data set divided by the number of values- the
average
median - ANS-the middle value- separating the greater and lesser halves of the data set
mode - ANS-the most frequent value in a data set
normal distribution - ANS-measure of magnetism- uses the bell curve
bad science - ANS-when people mislead consumers by misusing scientific research
reported to the public by the media
publication bias - ANS-companies sponsor studies and have the last word in whether
results could be published at all- will choose to publish the positive results, and never
reveal the negative results (outcome influences the decision to publish)
p value - ANS-degree of probability or improbability of a certain result in an experiment-
the probability that the observed results could occur by chance alone
statistical significance - ANS-the likelihood that something occurs by chance alone
certainty - ANS-knowledge that has total security from error/being reliably true
will almost never occur in experiments because there will always be uncertainty in a
variable
law of small probabilities - ANS-the fact that the probable is not always what will
happen- the most improbable things are bound to happen occasionally
confidence intervals - ANS-a range of values within which the true result probably falls-
narrower means lower likelihood of random error
power - ANS-when you have sufficient data to achieve the desired level of confidence in
the outcome of a study- probability of finding an effect if there is one
false positive - ANS-when the study finds an effect that isnt real- test positive for a
disease but dont have it (b)
