Answer: Ordinal scale.
Explanation:Ordinal scale is the level of measurement that gives the ranking of data without showing the degree of variation between them. It helps in identifying if object has more or less characteristic when compared to another object but does not tell the exact weight of the characteristic. Data in Ordinal scale is usually given in order of magnitude since there is no standard of measurement of differences. For example 1=most willing to 5=least willing.
