ASSIGNMENT 2
*QUESTION 1: DATA COLLECTION**
1. 1.1.1 **Random variable of interest:** Mode of transport used by learners to get

2. 1.1.2 **Population of interest:** All Grade 10 learners at Praise Convent School.
3. 1.1.3 **Sample of interest:** The learners Mrs. Zinzi surveyed and from whom
she recorded the modes of transport (the 25 responses).
4. 1.1.4 **Nature of data:**
* **Qualitative Data:** The data is qualitative because it describes a quality or
characteristic (mode of transport) rather than a numerical quantity.
* **Categorical Data:** The data is categorical because it falls into distinct
categories (Car, Bus, Walk, Bicycle). These categories are mutually exclusive, and a
learner can only belong to one category for a given day.
5. 1.1.5 **Measurement Scale:** Nominal. The data is at a nominal level because it
only represents categories with no inherent order or ranking. You can't say one
mode of transport is "higher" or "lower" than another in a meaningful numerical
sense.
6. 1.1.6 **Critique of Survey and Alternative:**
* **Critique:** A survey is a reasonable starting point, but it might have
limitations. Learners might not accurately recall their mode of transport, especially if
the survey is administered at the end of the day. Also, a survey relies on self-
