Adding Data
Data is added to a stage after defining all the input and output variables (Properties).
Clicking on Properties will give a pop up form listing all the properties associated with a Stage. A user can then add a new property by giving a Title and Type of property. There are predefined Types of properties (like Text, Number, Upload File, Barcode etc) which a user can use for adding a Data Property.
Suppose a User want to create a simple Linear Regression model for Real GDP (world) vs Year as a variable then a User can add 2 new Properties namely Year and GDP. Keeping TYPE as Number for both the variables. User can also add a new Property namely newYear (keep TYPE as Computed) for getting the normalized values later.

A Property is associated with a Question a User can submit (to be shown on the data input form). A User can also mark a Property as Required.
Date and Number Types of properties can also be provided with limits on maximum and minimum.
When a User creates any Properties (Variables) of Numbers, Choice or Multiple Choice Types a User gets to add Single Variable Charts (Pie Chart, Line Chart or Histogram) or Multiple Variable Charts (BoxPlot) on the User Dashboard.
Clicking on Data will give a Pop up form to manage the data. A User can Add Data, View Data and check Data Spread here. Data can be added in the form or can also be uploaded using a Excel Sheet. A User can also Download a Sample file for uploading the data.
