, QUESTION 1
1.1.1
The random variable of interest is the mode of transport learners use to get to
school.
1.1.2
The population of interest is all Grade 10 learners at Praise Convent School.
1.1.3
The sample of interest is the learners who were randomly selected and surveyed by
Mrs. Zinzi.
1.1.4
The data is qualitative because it describes a characteristic (type of transport) rather
than a measurable quantity.
It is also categorical because the responses (Car, Bus, Walk, Bicycle) represent
categories or groups without any inherent numerical value or order.
1.1.5
The measurement scale is nominal. This is because the modes of transport are
names or labels without any ranking or order. “Car” is not higher or lower than “Bus”;
they are just different categories.
1.1.6
A survey is appropriate for gathering quick responses from a large group and is
cost-effective. However, it depends on self-reported data, which can be inaccurate
due to misunderstanding or dishonesty.
