Correct option is D
A. Thirty or more → III. Large Group
The phrase "thirty or more" typically refers to a large group in the context of research or statistical sampling. It is a common threshold to consider a sample size large enough for statistical analysis.
B. Discrete → IV. Type of Data
Discrete data refers to data that can take only specific, distinct values (e.g., number of people, number of items). It is a type of data and contrasts with continuous data, which can take any value within a range.
C. Interval measurement → II. Scale
Interval measurement is one of the four scales of measurement (nominal, ordinal, interval, ratio), where the intervals between values are equal but no true zero exists. It directly relates to the concept of a measurement scale.
D. Dispersion → I. Range
Dispersion refers to the extent to which data points differ from the central value (mean). The range, calculated as the difference between the maximum and minimum values, is the simplest measure of dispersion.
