a. Location in which respondent was born

in nominal level measurement, we cannot make any statisticalinferences. they are only description, example: name of people, gender

in ordinal level of measurement, we can rank items and make comparisons of what is greater than or less than. example, exam rank

Ratio and interval measurement can have all statistical measurements. Ratio scale has an absolute zero and the interval scale does not. example of ratio scale, height, weight and a zero indicates absence of the measurement

Interval scale example,temperature. Does not have an absolute zero as the temperature can go beyond zero; example -5 degrees
