Explanation

Ordinal variables have ranked categories, matching rank of army personnel and level of irritation.

Religion is a nominal variable with unordered categories.

Caste is also nominal, naming groups without inherent order.

Temperature in Celsius is an interval variable with equal gaps and an arbitrary zero.

Ordinal data support the median and rank based tests but not the mean.

Ranks show order without an equal distance between successive positions.
