Document Summary
Is there a relationship between variables: inferential statistics, they allow us to make (probabilistic) conclusions about large populations that we have not measured, on the basis of smaller samples that we have measured. Level of measurement: variables can be measured at different levels, nominal: classification into categories. Tally lll ll lll l l l l. 1: ordinal: classification into categories plus ranking of categories with respect to one another e. g. likert-type attitude scale. Please indication your level of agreement with the following statement: section 33 should be eliminated from the constitution act, 1982: strongly disagree (1, disagree, neutral, agree, strongly agree. Polsci 3nn3 winter 2018: we do not know the distance between the chooses, interval-ratio: categories are classified, ordered, and have equal distance between them. Income ( in dollars: age (in years, voter turnout (%, gdp/capita (dollars/ person, these are actual numbers you can compare.
