QUESTION 1
1.1.1. The mode of transport used by the learners to get to school
1.1.2. The Grade 10 learners at Praise Convent School.
1.1.3. Group of learners Mrs. Zinzi randomly surveyed.
1.1.4. The data is qualitative and categorical. It is qualitative because it describes
attributes (modes of transport) rather than numerical values.
- It is categorical because the responses are grouped into distinct categories.
1.1.5. Nominal. Because the data is categorized into named groups without any inherent
order or ranking.
1.1.6. An alternative method would be direct observation. Mrs. Zinzi (or a designated
observer) could stand at the school entrance and record the mode of transport
used by each Grade 10 learner arriving at school. direct observation would provide
more accurate data, reducing the potential for recall bias or dishonesty inherent in
self-reporting.
1.1.7. Mrs. Zinzi's sampling method appears to be random, which meets the
requirements of a probability sampling method.
1.1.8. Advantage – is surveys are relatively quick and easy to administer, especially for
a large sample size.
Disadvantage – the reliance on self-reporting can lead to inaccurate data due to
recall bias or untruthful responses.
1.1.9. Stratified random sampling would improve representativeness. Mrs. Zinzi could
divide the Grade 10 learners into strata (e.g., by gender, class, or neighbourhood)
and then randomly sample from each stratum proportionally to its size in the overall
population. This ensures that subgroups within the Grade 10 population are
adequately represented in the sample, leading to more accurate and generalizable
results.
1.1.10. The data is primary because Mrs. Zinzi collected it herself directly from the source
(the learners) making it primary data.
1.1.11. Primary data collection is more reliable for Mrs. Zinzi's purpose. While secondary
data might be available, it is unlikely to directly address her specific research
question about learners' modes of transport. Primary data, even with its limitations,
provides more relevant and reliable information.
