,QUESTION 1: UNDERSTANDING DATA
1.1 Identify the population and sample in this study. Support your answer with
reference to the Eastern Cape context.
Population
The population refers to the entire group that the researchers are interested in studying.
In this case, the population consists of all Intermediate Phase teachers in the Eastern
Cape district from which the workshop participants were selected (Berenson, Levine &
Szabat, 2021).
Sample
The sample refers to the smaller group selected from the population to participate in
the study. In this dataset, the sample consists of the 19 Intermediate Phase teachers
who attended the professional development workshop and provided information about
their travelling distance, number of coins carried, and favourite colour.
The sample represents only a portion of the teachers from the district and not all
teachers in the Eastern Cape or South Africa.
1.2 Identify the three variables in the dataset and describe what each represents.
Variable Description
Distance (km) The distance in kilometres between each teacher’s home and school.
The number of coins each teacher was carrying at the time of the
Coins
workshop.
Favourite
The colour preferred by each teacher participating in the workshop.
colour
, 1.3 For each variable, classify it as qualitative or quantitative and categorical or
numerical. Provide a justification for each classification using the dataset.
Variable Qualitative/Quantitative Categorical/Numerical Justification
Distance is measured
using numbers such as 3
Distance
Quantitative Numerical km, 15 km, and 30 km.
(km)
The values represent
measurable quantities.
The number of coins is
counted numerically
using values such as 0,
Coins Quantitative Numerical
4, and 11. This makes it
measurable and
numerical.
Favourite colour
consists of categories
Favourite
Qualitative Categorical such as black, blue,
colour
grey, and white rather
than numbers.
1.4 Identify the measurement scale (nominal, ordinal, interval, or ratio) for each
variable. Justify each answer.
Measurement
Variable Justification
Scale
Distance has a true zero point because 0 km means no
Distance
Ratio scale travelling distance. Differences and ratios are
(km)
meaningful (Upton & Cook, 2014).
The number of coins has a true zero because a person
Coins Ratio scale can carry 0 coins. Values can also be compared
meaningfully.
Favourite Favourite colours are names or labels only and cannot
Nominal scale
colour be arranged in a meaningful order.
