Week 5
Cards in this deck (5)
- 1Holisti'sused with NOMINAL level data
used to calculate percentage or agreement between two coders
run on each item in a code book
acceptable level of reliability: min 90% better 95%
^because formula doesn't consider agreement by chance^ - 2Holist's FormulaM: # of coding decisions on which 2 coders agree
N1: # of decisions by first coder
N2: # of decisions by second coder
RELIABILITY = 2M / (N1 + N2) - 3Scott's Piused with NOMINAL level data
% of observed agreement between coders
% of expected agreement between coders (agreement expected by chance)
the agreement you REALLY get divided by the max you COULD get if you take agreement by chance out.
acceptable level of reliability: min 85% better 90% - 4Scott's Pi FormulaRELIABILITY = % observed agreement — % expected agreement / 1— % expected agreement
