Numeric Fields: Adding and Setting Properties
Numeric fields can be used to capture any kind of data. They can have max and min settings applied to them through to specific unit types. Use Numeric fields when you want to capture number based data that will be used for in depth analysis. This includes:
* Physiological test data: distance, time, length, speed etc
* Blood testing data: from lactate to glucose
* Heart rate and training data: distance, fatigue etc
* Capturing lifestyle measures: such as hours of sleep
The number fields that are available include numbers, whole numbers and positive whole numbers etc.
To Add in a Numeric Field into your event form, click on the type of number that you require. The example here is going to use a "Number"
Adding a Numeric Field into your Form
To Add in a Numeric Field you will need to select the Type of field from the Form Builder "Add Question" Options (as highlighted in 2.3.2). For this example we are going to build an Anthropometry Form with weight, height and 4 skin folds. They are all built with the "Number" Field and the properties are set differently to mimic the data that we need to capture.
Name the Question, add in instructions and set up any default values. For this height example we will want it to default to the last value. Set up any visibility settings also.
Set the Advanced Properties for that field including Best Value
This is where you start to give the information you collect meaning. It is used to show whether an athlete has improved or decreased their performance when it compares the most recent with the new new entry information. It is essential that it is set up, or your Performance Summary Dashboards, trending arrows on the history and data entry pages, and ranking capabilities will NOT show.
- Higher Values are best: If you set that "Higher values are best" then you are specifying that if a record of 2.0 exists, if the athlete enters 3.0 they have improved. However, if they entered 1.0 the reports would show they have not improved. For variables such as weight lifted, number of repetitions, speed, distance, VO2 etc, higher values are always best.
-Lower Values are best: If you set that "Lower values are best" then if a record of 2.0 exists, and the athlete enters 3.0 they have not improved. However, if they entered 1.0, the reports would show that they have improved. For variables such as skin folds, sprint times, lactic acid, resting heart rate etc, lower values are always best.
For the example of building an Anthropometry Form, the following settings are going to be used:
Height: Higher values are best
Weight: Lower Values are best (endurance runners are the target group)
Triceps: Lower values are best
Suprailiac: Lower values are best
Abdominal: Lower values are best
Thigh: Lower values are best
Max and Min Values. Will a max a min help to minimise data entry errors? For height in metres you can set a min of 1 and a max of 3. This will minimise user error
Reduce data entry errors and set up the number format correctly using the Maximum and Minimum Values, and Format Properties.
Maximum and Minimum Values
This allows you to set an upper and a lower range for the each numeric field. This helps to stop data entry errors, because values outside of this range will not be saved and will show as an error on the Event Form in the Application. Simply type in the Minimum and Maximum values into the corresponding boxes as shown above, and no data outside this range can be entered into this field.
The form will not be able to be saved when a variable outside of your max and min range is entered. The min and max values will appear in an error message informing them of the correct range.
Set up the format (decimal places) accordingly for the type of data you are capturing. For height in metres we will need 0.00
Enables you to turn any number in a 1, 1.0, 1.00, 1.000, 1.000 decimal point value. This is essential to set when you start to create your forms. A lactate value will have 2 decimal places, but a heart rate will have none.Set your number formats according to the information you are capturing: a heart rate will look ridiculous if it is recorded 178.00 (2 decimal points) versus 178 (no decimal points).
For the example of building an Anthropometry Form, the following Format and Max and Min settings are going to be used:
Height: Format 0.00, Max and Min 3 and 1 (respectively)
Weight: Format 0.00, Max and Min 200 and 50 (respectively)
Triceps: Format 0.00, Max and Min 40 and 0 (respectively)
Suprailiac:Format 0.00, Max and Min 40 and 0 (respectively)
Abdominal:Format 0.00, Max and Min 50 and 0 (respectively)
Thigh: Format 0.00, Max and Min 50 and 0 (respectively)
How to add a unit Type and Units to a field-e.g. weight in kg's or height in metres
Get Specific with your Numbers
Unit Type and Units
Units are an excellent tool to place additional structure around the data that you capture. The image above highlights how you can easily turn a number into a field that has a lot more meaning, and easily lets the person entering the information know the units of measure. This helps with recognition when completing the form, and most importantly reduces errors in the data. e.g. if some Users enter in centimetres and others enter in metres.
To Add A Unit to a Field
#1: When you select the "Unit Type" drop down arrow a list of all of the available Unit Types is displayed for you to select.
#2: The corresponding Units (for the respective Unit Type) are then displayed in the "Units" drop down list (as shown in the image above). Simply select the Unit that you require and it will automatically be added to the Numeric field question (as shown in the image above as millimetres).
Available Unit Types and Units are listed below:
Unit Type Unit Types
Length millimetres, centimetres,metres, kilometres, inches, feet, yards, miles
Speed metres per second, kilometres for hours, feet per second, miles per hour
Weight grams, kilograms, ounces, pounds
Small Weight grams, milligrams, micrograms
Volume millilitres, litres, fluid ounces, gallons
Time milliseconds, seconds, minutes, hours, days, weeks
For the Anthropometry Form example, the following Unit Types and Units were added to the Anthropometry questions:
Height: Unit Type -Length, Units-metres
Weight: Unit Type -Weight, Units-kilograms
Triceps: Unit Type -Length, Units-millimetres
Suprailiac:Unit Type -Length, Units-millimetres
Abdominal:Unit Type -Length, Units-millimetres
Thigh: Unit Type -Length, Units-millimetres
