Info
titleKey Considerations
  • Numeric answers are used when a respondent must provide a number to answer to a question.
  • Where a numeric answer requires a unit or other qualifying information, it should be added as a text answer. For example, ‘Give your height in centimeters’ is a number, whereas ‘Give your height’ is a text answer as the unit needs to be specified in the answer.
  • They are either an Integer or Float numeric type. Integers are whole numbers only. Floats allow a decimal place.
  • For most numeric responses a generic answer labelled ‘How many’ is used.
  • Formats, minimums and maximums matter so ‘Number (Integer, Min: 0, Max: 10)’ is not the same as either ‘Number (Float, Min: 0, Max: 10)’ or ‘Number (Integer, Min: 0, Max: 20)’.

Numeric answers with specific labels

 There are several types of numeric answers which are specifically labelled:

Note: Specifically labelled answers are not created for distance (i.e. miles), single unit time responses with no defined min or max in the documentation (i.e. hours only, minutes only), and measurements without a defined length or size (i.e. days, nights, slices, cups, mugs, etc.). These are all entered as a 'How many' response domain.

...

 Answers to ‘How old’ questions are entered as follows:

Measurements

Physical measurement responses with a defined length or size are input as labelled numeric answers regardless of whether the question response contains a single measurement (inches, cm, mm, kilos) or a compound measurement (… lbs … oz; … stones … lbs; … ft … in). The answer label for the measurement unit should be fully spelled out regardless of how it is written in the questionnaire.

Quantities

Quantities which have a precise unit of measurement are entered as specifically labelled numeric answers. Tablespoons, teaspoons, fluid ounces (fl.ozs), centilitres (cls), millilitres (mls), and grams are examples of quantity responses that are entered as labelled numeric answers. Responses asking average amount per serving, no of cups/mugs of tea/coffee (see example ), glasses, spoons, slices, scoops, bananas, eggs, etc., where the serving size is variable (see example), are not entered as specifically labelled numeric answers. ‘How many’ is used as the answer for these types of quantities.
