This data set contains A) 4 Variables, 1 of which is quantitative
Why is this? Because the four variables are
- Gender
- Age
- Birth month
- Read horoscope
Age is quantitative because it deals with a quantity or number. We can do things like find the average age and it makes sense to do so. The other variables are qualitative or categorical. Gender is nominal as you can't order the data. Birth month is ordinal though because we can order the months from January to December. The responses for "read horoscope" are nominal data because we cannot order "yes" versus "no".
