P value correct answers the true probability that the test statistic would be as far from expected as it is IF the null hypothesis is true Induction or falsification? correct answers Falsification - induction is logically invalid - science must proceed by eliminating false ideas Hypothesis testing: confidence interval correct answers - it is not true that there is a 95% chance that the parameter is in the 95% confidence interval - there is a 95% probability that if you collect another s...

Probability in Bayesian terms (as opposed to classical) correct answers How confident you are that a hypothesis is true Time in Bayesian vs. Classical correct answers Generally you cannot update classical models as time goes on, you can with Bayesian Product Rule correct answers P(A, B) = P(A) * P(B|A) *** Only if A and B are independent Sum Rule correct answers P(A) = P(B) * P(A|B) + P(nB)*P(A|nB) (nB is not B) OR P(A) = Σ P(Bi) * P(A|Bi) Bayes' Rule correct answers P(...

Prior Distribution correct answers

Define thinking correct answers the flexible organisation and manipulation of internal representations helps us to understand the world processes of thinking correct answers physical stimuli - sensory representation - semantic representation - desired goal - plan how are representations formed? correct answers depends rationalism (through a priori knowledge) vs empiricism (through sensory system) constructivists (apriori) vs sensory driven (empiricists) what is perception corre...

in general, the goal of statistics is to correct answers make an inference using observed data,x to make an inference, the data is assumed to have originated from a probability model _________ and our inference is usually expressed in terms of an unobservable parameter ____ of the distribution ___ correct answers f(x|θ) θ f The Frequentist approach to statistics adopts the view that correct answers only the data, x, is random The fundamental principle of Bayesian statistics: everythin...
