Document Summary
Count frequency table, exact values (1, 5, 345 etc) Magnitude of each data should be accurately represented in comparison to one another. The sum of counts/frequencies should equal the total sum of variable or to 100% Data of only one of the two variables. Table where data falls into named categories on two or more variables. Distribution of variable restricting to a particular level within a variable to only consider a small group of individuals. Ex: distribution of scores among those who studied >60min. Looking at trends between the two variables will determine if they are dependent. Ex: looking at number of deaths on the titanic rises as ticket class decreases. Displays conditional distribution of a categorical variable within each category of the other categorical variable. Ex: survivors and deaths displayed for each ticket class. 1st (alive/dead), 2nd (a/d), 3rd (a/d), crew (a/d)
