Nominal, Ordinal, Interval, Ration (NOIR) 1 of 17 What is nominal data ? Data which has been collected in catagories using tallies (ie. Coding schemes) 2 of 17 What is ordinal data? Data which records the order of participants scores eg. 1st, 2nd, 3rd OR data collected from unoffical scales 3 of 17 What is interval data? Data collected from offical scales, can contain negatives eg.Temperature 4 of 17 What is ratio data?
