11.1 Goodness-of-Fit

goodness-of-fit

an idea for testing whether a group of counts is distributed in a way that is expected - this is a hypothesis test

10% condition

the condition that states the sample is less than 10% of the population of interest

cell

an element of a table that corresponds to a specific row and column - table cells can contain counts, percentages, or measurements on variables, and some hold more than one value

randomization condition

the condition that states the counts should be from a random sample of the population of interest

expected counts

the value you expect to be in a cell - these indicate the distribution of the counts into groups if they were distributed completely perfectly

counted data condition

the condition that the values in each cell of a table must be counts for the categories for a categorical variable - the methods discussed in this lesson cannot be applied to proportions, percentages, or measurements just because they happen to be organized in a table

expected cell frequency condition

the expectation of seeing more than 5 individuals in each cell
