Tim.bates@ed.ac.uk. http://www.psy.ed.ac.uk/events/research_seminars/psychstats. Resources. http://www.statmethods.net. Our basic question…. Did something occur?. Importantly, did what we predicted would occur, transpire?, i.e., is the world as we predicted?. Probability in psychology (. P = <. 0.05). The.  . p (probability).  value determines whether or not we reject the null hypothesis. We use it to estimate whether or not we think the null hypothesis is true. . Types of Inference. Estimation. : On the basis of information in a sample of scores, we estimate the value of a population parameter.. Hypothesis Testing. : We determine how well the data in the sample fit with the hypothesis that in the population a parameter has a particular value.. 2017. CSE 331.

Grid computing usually consists of one main computer that distributes information and tasks to a group of networked computers to accomplish a common goal.. Inferential statistics. :. Based on laws of probability. Used to estimate population parameters from sample statistics . When different researchers apply inferential statistics to the same data resulting conclusions likely to be the same. Zero In on the Null. To . perform a hypothesis test, the null must be a statement about the value of a parameter for a model. . We then use this value to compute the probability that the . observed. sample statistic—or something even farther from the null value—might occur.. I can interpret . P. -values in context.. QUESTION. : When we are testing hypotheses, what would be strong evidence . against. the null hypothesis (. )?.
