How can i create ranges for a variable?

So, using the Aggregate function I need to make a chart presenting the standard deviation of "Mo_Income" separated by gender and by international limit. And also I will have to create ranges for the variable first.

Im doing well with the first part but i don´t know how to create the ranges for the variable

    Hi @Tdragi13
    Can you share a sample of your data?
    in order to discretize your dataset you can use, for example the Discretize by User Specification operator, (go to Cleansing->Binning).
    Another option is creating  a new Attribute using logical functions and value intervals.

    Hi @Tdragi13

    this is a simple example appliying the Discretize by User Specification operator.

    next time, please share the process or dataset. 

    Best.
