Question

which of the following variables would be considered to be measured on a continuous scale?

age

Gender

Religeon

proncipal diagnosis

Answer 1

Gender clearly is a dichotomous variable which is a categorical variable as it could only have 2 categories and so it cannot be put on the continuous scale. The same case is with the variable religion which is a categorical variable and so it cannot be continuous.

We know that Age is a numerical variable and also there could be ages in between two ages, like between 2 and 3 years, which shows that it is a continuous numerical variable

Therefore Age should be the correct variable here.
