Tell a 'how much?' measurement from a 'what type?' label, and spot labels that have an order.
Classify any research variable as continuous, counted, nominal, binary or ordinal, and tell counted from ordinal by whether the gaps between values are equal.
How much vs what type (the step you are on)
Kitchen cards sort into 'How much?' (grams of flour) or 'What type?' (kind of flour).
Grams of flour answers ‘How much?’; the kind of flour answers ‘What type?’. Drag each card into its bin: 6 to sort.
