Filters are the simpler and straightforward feature in Tableau. It applies to dimension or measures directly. For example, to only show Gujarat or Karnataka in a State dimension, we can apply the filter on that. In Tableau, there are multiple UI options available for filters like radio buttons, drop-down lists, checkboxes, sliders, and more. Filters on sheets are also available in Tableau.
Parameters are like variables. They are complex and more powerful. Like a variable, a parameter can be used in calculations. So, that means, it only allows single value. Parameters have same UI options except for checkboxes because checkboxes don’t have a single value. For example, we can create a parameter for interest rate and period, and then we can use these parameters to calculate interest and principal payments.
