Correct option is C
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 → I. Range
Interval measurement involves data that is measured along a scale where the intervals between values are consistent. The range is the difference between the maximum and minimum values in interval data, making it relevant to interval measurement.
D. Dispersion → II. Scale
Dispersion refers to the extent to which data points differ from the central value (mean), and it relates to the scale of data. For example, measures like range, variance, and standard deviation describe the dispersion within a dataset.
