Document Summary
Descriptive: used to describe characteristics of a population or a sample: describe the form of your data. Inferential: used to generalize from a sample to the population from which the sample was drawn. They involve using a sample to make inferences about the population: the better, more useful stat, tell us wether or not we can relate to the broader population, generalize from small to general population. Distribution: a list of the number of observations in each category of the variable, it displays the frequency with which each possible value occurs. Use percentages when we have larger numbers. Pie charts do not allow us to analyze anything more than one variable. Describing bivariate data in a bar chart. Central tendency: a measure of central tendency indicates the most typical value, but one value that best represents the entire distribution. These two are linked to level of measurement.
