The empirical rule - Study guides, Class notes & Summaries

T/F: Every estimator has a sampling distribution that is identical to the distribution of the population of interest - ANSWER False T/F: Chebychev's Theorem is used to help understand the concept of a standard deviation and applies to any random variable - ANSWER True T/F: The empirical rule is used to help understand the concept of the location of a population and applies only to symmetric unimodal continuous random variables - ANSWER False T/F: The empirical rule is used to help underst...

Probability - Independent Events The occurrence of one event does not affect the probability of the other. -If A and B are independent events, then P(A and B) = P(A)•P(B) Theoretical (Classical) Probability Count the number of outcomes and divide by the total possible outcomes. Theoretical probability requires that the experiment be fair. Empirical Probability (Relative Frequency) Perform the experiment multiple times (trials), count the number of times the event occurs and divided...

99.7 Rule Rule, or Empirical Rule [1] In statistics, the 68-95-99.7 rule or three-sigma rule, or empirical rule — states that for a normal distribution, nearly all values lie within 3 standard deviations of the mean. This rule is often used to quickly get a rough probability estimate of something, given its standard deviation, if the population is assumed normal, thus also as a simple test for outliers (if the population is assumed normal), and as a normality test (if the population is...

Experiential reality -Things we know from direct experience Agreement reality -The things we consider to be real because that's what we've been told & everyone else seems to agree; what everyone "knows" to be true -Where most scientific knowledge comes from Selective observation - Picking homogeneous groups of people to study when observation group is broader than that; opposite of representative sample - If you start an experiment and stop it early; throws off normal dist...
