Answer 1

Identify the measurement scale for each of the variables:

(1) The daily temperature: Interval scale

(2) The name of students registered at Unisa in 2020: Nominal scale

(3) The size of a soft drink 500ml, 1 litre, 1.25 litre and 2 liter: Ordinal scale

(4) The salary of a nurse working in a public hospital: Ratio Scale

(5) The rank of employee at UNISA ( junior lecturer, lecturer, senior lecturer, professor): Ordinal scale

Explanation:

We use nominal scale when we have to describe names only. If there is specific order under variable, then this is ordinal scale. If there is numbers without real zero, then we use interval scale. If we use contiuous or discrete data, then we have ratio scale.
