... (2) is called sometimes Bayes’ rule. It is often used in a context where we want to know the probability that a particular hypothesis is true. We have an a priori belief in whether or not the hypothesis is true, then update that probability by collecting data. E.g.: Suppose a priori boys are equally ...

... After the assignment, Mrs. Smith had 30 students, and Mrs. Jones had 25 students. At the end of the year, each class took the same standardized test. Mrs. Smith's students had an average test score of 78, with a standard deviation of 10; and Mrs. Jones' students had an average test score of 85, wi ...

... Applied statistics The basis for statistics is data / observations observed with random variation. We want to quantify the variation in the observations due to • systematic variation • random variation due to factors we cannot control We need to • summarize many observations as simple as possible • ...

... function approaches the Y axis asymptotically but never gets there. A usual method of dealing with raw data where many of the values are less than 1 is to add an arbitrary constant to the entire data set and then log transform; in this way we avoid dealing with negative numbers. What does all this m ...
