PSYC 2301 Lecture 2: Chapter 2 Notes
Document Summary
Tools you will need: proportions (math review, appendix a) Continuous and discrete variables (chapter 1: real limits (chapter 1) 2. 1 frequency distributions: a frequency distribution is. Showing the number of individuals located in each category on the scale of measurement: can be either a table or a graph, always shows. The frequency, or number of individuals, in each category. 2. 2 frequency distribution tables: structure of frequency distribution table. Categories in a column (often ordered from highest to lowest but could be reversed) Frequency count next to category: f = n, to compute x from a table. Percentages: expresses relative frequency out of 100, percentage = p(100) = (f/n)(100, can be included as a separate column in a frequency distribution table. If the number of categories is very large they are combined (grouped) to make the table easier to understand: however, information is lost when categories are grouped.
