Document Summary
Probabilities of k outcomes, sometimes denoted as p1, p2, pk remain. Random variables of interest are the cell counts of the number of the same from trial to trial observations that fall into each of the k categories. Categorial variables - measurements consist of categories. One-way tables - used to summarize results from a multinomial experiment. only one variable is being classified. We always start an experiment by assuming the null hypothesis is true. Has upper-a critical points given in tables. Degrees of freedom = k-1 where k is the number of categories. 1. a multinomial experiment as been conducted. this is generally satisfied. 2. the sample size, n, must be large enough so that for every cell the. Gof tests are likely to be performed by people who have a theory of what the by taking a random sample for the population of interest. expected cell count . This type of data can be represented in a .
