💡 Lời giải chi tiết:
According to sampling theory, sample frame error arises when the list of people from which the sample is drawn does not accurately represent the entire target population. Kết luận Lý giải: Sample frame error
Câu 12:Which level of measurement allows researchers to categorize and rank data but does not imply equal intervals between the ranks?
💡 Lời giải chi tiết:
In the hierarchy of measurement, an ordinal scale provides a rank order of objects but does not quantify the precise difference between them. Kết luận Lý giải: Ordinal scale
Câu 13:What type of data analysis explores the strength and direction of a relationship between two variables?
💡 Lời giải chi tiết:
According to statistical analysis standards, correlation analysis is used to measure how two variables move in relation to each other without implying causation. Kết luận Lý giải: Correlation analysis
