You can use calculations/formulas.
First, you need INDEX() which retrieves values based on the table or collection row, and ROW() which gets the current row number.
INDEX(Table.Column1,ROW())
Now you want to check two values, so you use an IF function combined with an AND operator
IF(AND(INDEX(Table.Column1,ROW())>=1,INDEX(Table.Column1,ROW())<=50),"True","False")
Just replace the true/false values with the values you actually want, and replace the Table.Column1 variable with the actual variable names from your table.
(easiest way to make sure they are correct is to go to the Advanced tab of your second column, click the > button for the function, scroll to the bottom with the tables/collection, and select it from there).
NOTE: if you can have decimals, then you don't want both >= and <= because that would create gaps that aren't covered. For example 51 >= 50.5 <=50.
Instead you might want >0 & <=50, >50 & <=100, >100 & <= 150, it just depends on what you need and how your cutoff points should work.
