PSY201H1 Study Guide - Quiz Guide: Binomial Distribution, Null Hypothesis, Statistical Hypothesis Testing
Document Summary
Lecture 7 - introduction to hypothesis testing using the sign test. The probability of something is never zero but rather lowest possible probability will. If we let p represent students and q represent non-students: p(p) = . 75 but that is not listed on the table, so therefore find p(q) which = . 25. Matched to a statistic: e. g. sum of, mean, correlation, etc. All possible values a statistic can take. Probability of getting each value if only chance is operating. Some outcomes are more likely to happen just by chance alone. Binomial distribution is modeling chance to fact. In our study, we want to rule out chance we want to find something real. The sign test: using the binomial distribution to calculate. Summarizing and filtering out chance allows to draw broader conclusions about hypotheses. Ruling out chance: design a study to test a hypothesis, gather data, analyze data with appropriate test, draw conclusions about hypothesis. Basic trivia test (0-12: step 2:
