Document Summary

Haan: an introduction to statistics for canadian social scientists. Levels of measurement, a brief review: nominal: responses cannot be ranked, and distance between response categories cannot be measured, ordinal: responses can be ranked, but distance between response categories cannot be measured. Interval: responses can be ranked, distance can be measured, but there is no theoretical zero: ratio: same as interval, but there is a theoretical zero. Frequencies with nominal data: frequency tables usually contain two vital pieces of information: the identifier (response category, e. g. , sex) and the frequency (count, percentage, and/or proportion). Identifiers are usually on the left [column], often sorted alphabetically: the right column contains the frequency distribution. 49. 14: female/(female+male)=proportion, female/(female+male) x 100 = percentage, always round to two decimal places. Necessary equations for nominal frequencies: n= total number proportion = f. Nominal frequencies, continued: table 1: number of males and females in the canadian population, 2001 census of.
