If a set of scores for a variable is displayed in a frequency distribution polygon, which scale of measurement was used to measure the variable

Given: The set of scores for a variable is displayed in a frequency distribution polygon.

To find: We need to find which scale of measurement was used to measure the variable

Solution: A frequency distribution table is always either in interval or in ration scale.

1 is not true because 12x does not have a y in it
2 is true
3 is not true because 12x does not have a y and 24y does not have a x
4 is true
5 is not true because 24y does not have an x in it
6 is true
7 is not true because 24y does not have an x in it
8 is true
