Document Summary
An organized tabulation of the number of values located in each category on the scale of measurement. Count the number of times each value appears: Note that we have 2 columns, but we are still talking about 1 variable. *count each value as many times as it appears in the data. The fraction of the total group that is associated with each possible score is called a proportion or a relative frequency. Divide the number of observations that got the score you are interested in by the total number of the observations you have. Proportions and percentages make it easier to see the relative share of observations at each possible value. The value: occurs ___ times: out of 10 total. The best way to display frequency distributions for nominal or ordinal data. All the values between 1-5; all the values between 6-10; etc. When we have lots of data and lots of possible values, we need to choose bins wisely.
