Document Summary
Can ask more speciic quesions with higher levels of measurement: staisical signiicance can the relaionship be generalised in the populaion from which the sample was drawn (only relevant with samples). Use the cross tabulaion to look at whether there seems to be covariaion in the data. You eliminate non-responses and responses that are irrelevant (e. g. people who voted for the. Rhino party in this example) for nominal level data, but not for other levels of data. You can combine categories in ordinal level, but you can"t drop them. To be able to use the data more efecively, we turn the numbers into percentages. The cell percentages must be calculated in terms of the total number of cases in each category of the iv. Generally you should have the dv in columns and the iv in rows idk if this is right i think it"s wrong.
