- 1Strengths of Nominal DataEasy from closed questions
Large amounts of data quickly
Reliable - 2Weaknesses of Nominal DataNo linear scale = unable to express degrees of response
No linear scale = means cannot be assessed
Can only use the model as measure of spread - 3What is Nominal Data?Names / labels in any order
No quantitative data
e.g. hair colour - 4Strengths of Ordinal DataMore info than Nominal
Indicates values on a scale
Easy to generate from rating scales
Points on linear scale = median and mode - 5Weaknesses of Ordinal DataGaps between points are relative = ppts may interpret scale differently
Could make it invalid to compare them
Gaps between points are not equal = median cannot be assessed - 6What is Ordinal Data?Values on a scale are ordered in terms of significance / importance
e.g. satisfaction scale - 7Strengths of Interval DataPoints of equal value = more informative
Easy to generate from closed questions
Points are linear with equal gaps = median, mode and mean
Standard deviation can be used
Reliable, scientific measurements - 8Weaknesses of Interval DataScales with no scientific measures = no absolute baseline to the scale
Scoring zero could mean the scale does not measure it
Could be interpreted as the ppt not demonstrating that variable at all - 9What is Interval Data?Numerical scale where the order AND exact interval value is known
e.g. celcius thermometer
