Numeric answers are used when the response to a question is a number. A numeric answer consists of a Label, Type, Numeric type and Min (Minimum) and Max (Maximum) values.

The numeric type is entered as either 'IntergerInteger' or 'Float'. Which type to choose is chosen depends on the format of the response in the questionnaire. The numeric type ‘Float’ is used only if the response in the question contains a decimal point or requires a fraction (see examples). Min and Max values are always entered as whole numbers, regardless of the values indicated in the questionnaire.

For most numeric responses a generic answer labelled ‘How many’ is used, with a Numeric type of Integer and a Min value of 0 with the Max value left blank.

If an integer Integer and a float Float numeric type answer are needed for the same numeric response in a questionnaire, separate answers response domains are made for each numeric type, adding ‘I’ for integer and ‘F’ for float to the label. In the example below, the questionnaire contains questions with a ‘How many’ response with and without a decimal point.

The ‘How many’ response to question 7.4b contains a decimal point, while the response to 8.4 does not. Two ‘How many’ numeric answers are created, one with a numeric type of Integer and one with a numeric type of Float.

Numeric answers with specific labels

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

• Age-related numeric responses
• Physical measurements
• Quantities (generally food-related) 
• Numeric responses with min and/or max values defined in the question

• Date responses input as a numeric answer

• Time period (duration) responses input as a Numeric numeric answer

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 - entered as a How many answer), 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.

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.

When the answer is the second measurement in a compound response, the label is entered as ‘[X] in [Y]’, where [X] is the second part of the measurement and [Y] is first part. So for a response ‘… lbs … oz’ the label for the ‘oz’ numeric answer is ‘Ounces in pound’, with a Min of 0 and Max of 15 (for an integer response) or 16 (for a float response). For the response ‘… stones … lbs’ the label for the ‘lbs’ numeric answer is ‘Pounds in stone’, with a Min of 0 and Max of 13 (for an integer response) or 14 (for a float response).

Responses for medical measurements, e.g. blood pressure, peak expiratory flow rate, etc., are labelled using the unit of measure recorded for the medical check, not the procedure itself. The numeric response for blood pressure is labelled Millimetres and does not need to be distinguised distinguished from Millimetres used as a physical measurement. The label for peak expiratory flow rate, used to assess lung capacity, is Litres per minute.

Temperature, whether of a person or a room, is input as a numeric answer only if the question specifies whether the response is in Celsius or Fahrenheit. The numeric response is labelled either Celsius or Fahrenheit depending on the unit indicated in the question. If a question regarding temperature does not specify a unit of measurement, the answer is input as a text response labelled Temperature. See discussion of insufficiently defined numeric responses in Text answers section.

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.

MinMax MinMax

Numeric responses with Min and/or Max values defined in question

 Most of the time when a question asks ‘How many of [X]’ there is no restriction within the question as to what the numeric response to the question might be. However, some questions contain defined minimum or maximum values in the question text. A specifically labelled numeric answer is created when a question restricts the numeric answer that may be given in response to the question.

Note: Unlike text answers, the restriction must be written in words in the question or response text. A particular number of blank boxes for writing in a numeric response is not treated as defining a maximum value.

Date responses that ask only for the day in a month, or the month in a year, something occurred/will occur cannot be input as a date answer. A specifically defined numeric answer is used.

For a period of time response to be entered as a duration, it must meet the following criteria. The time period must be for a specific event, for a continuous period of time, and the period must be sufficiently described, so that the start and end of the event are discrete time points. Responses that do not meet these criteria for a duration answer are entered as numeric answers.

The Duration section of the date and time answers guidance provides a detailed discussion of the use of duration versus numeric answers. See also examples of time period responses that are entered as a duration answer and examples of time period responses that are entered as a numeric answer for more information.

Time period responses with only one time point (i.e. years only, hours only) are not sufficiently described to be entered as a duration answer and a ‘How many’ answer is entered (see example ). When a compound time period response is input as two numeric answers, the first element of the time period is entered as a ‘How many’ answer; the second element is entered entered as a specifically labelled answer (see example).
