Answer #1

Variables included in the survey are age (in years), favorite sports, number of siblings, high school grade point average and the marital status of parents.

Age is a numerical variable and it has meaningfull difference between two data values,so it is an interval level of measurement.

favorite sports and marital status of parents are categorical variables which have no numerical value and we can not arrange favorite sports or marital status of parents in order. So, these two are nominal level of measurement

Number or siblings and high school GPA are ratio level of data because these are quantitative variables which have meaningful zero point.
