Answer 1

Nominal variable

A nominal variable is defined as a variable which is used to
`\text{nam}e \text{ or label or categorize some particular attributes }` which are being measured.

An ordinal variable is the one in which the order matters, but the difference between any two orders does not matter.

In interval ratio variable is defined as the variable where the difference between any two values is meaningful.

The level of measurement for each of the following are :

1) Variables that are categorized in categories so that it is ordinal data.

2) Data scaled with the two categories her or his, so it is a nominal data.

3) Number of votes categorized in the intervals so it is Interval type data.

4) nominal data.
