Question

when 30 elder women were asked about the types of exercise that they most often participate in, the responses were walking(w), biking(b), jogging(j), yoga(y), running(r) and weight training(t). the data for the 30 women is given below.

what type of variable does this data represent?

discrete numerical

continuous numerical

categorical

ordinal

Explanation:

Categorical variables represent types of data which may be divided into groups. In this case, the data (walking (W), biking (B), jogging (J), yoga (Y), running (R), weight training (T)) are different categories of exercise. Discrete numerical variables are countable numbers (e.g., number of students). Continuous numerical variables can take any value in an interval (e.g., height). Ordinal variables have a natural order (e.g., rating from 1 - 5). Here, there is no numerical value or order among the exercise types, just different categories.

Answer:

C. Categorical
