# SOC222H5 Chapter 2: Chapter 2—Frequency Distributions

## Document Summary

Understanding how to construct and analyze frequency, percentage, and cumulative distributions. Understanding how to calculate proportions and percentages. Recognizing the differences in frequency distributions for nominal, ordinal, and interval-ratio variables. Frequency distribution a table reporting the number of observations falling into each category of the variable. Frequency distribution for categories of world region of birth for foreign-born. Frequency distributions are helpful in presenting information in a compact form. To standardize these raw frequencies, we can translate them into relative frequencies that is proportions, or percentages. A proportion is a relative frequency obtained by dividing the frequency in each category by the total number of cases. To find proportion (p), divide the frequency (f) in each category by the total number of cases (n). A percentage is a relative frequency obtained by dividing the frequency in each category by the total number of cases and multiplying by 100. Percentages are usually displayed as percentage distributions.
