Document Summary
Political science 3nn3 2018 lecture 2b: frequency distributions. Some basic formulas to get things started: 100 where f = frequency, or number of cases in any category n = number of cases in all categories.

You need to change them into percentages to interpret the data properly. You have been observing the liberal party in hamilton and have compiled some information about a small sample of party regulars. Sex of respondents, sample of liberal party of hamilton. First thing you do is pick out the variables. Second, you need to list the attributes in order. Social class of respondents, sample of liberal party of hamilton. The listing of the categories of the variable should reflect the intrinsic rank from low to high or from high to low. Age of respondents, sample of liberal party of hamilton.
