Document Summary
Two major types of variables that can produce different forms of data: categorical. You can not be 2. 7 liberal: measured. In many experiments the independent variable = categorical and the dependent variable. A quick introduction to different levels of measurement. Nominal level of measurement level of measurement at which numbers are only labels for categories. E. g. categorizing people into tall and short groups. Ordinal level of measurement level of measurement at which cases are arranged in rank position. It does not take into consideration how far the person above you or under you is. Interval level of measurement level of measurement at which each unit on a scale represents an equal change in the variable measured. We don"t need numbers to distinguish between one another. E. g. male and female, colours, hair type etc. We compared each item to a learnt concept (what counts as green, hair type or male) We can count the numbers in each category.
