Question 1 of 5
Regarding primary and secondary data, which of the following statements is/are true?
A. Primary data is collected through actual observation or measurement.
B. Secondary data is always more reliable than primary data.
C. Secondary data may be compiled from published or unpublished sources.
D. Primary data is collected only through mailed questionnaires.
A
A. Primary data is collected through actual observation or measurement.
B
B. Secondary data is always more reliable than primary data.
C
C. Secondary data may be compiled from published or unpublished sources.
D
D. Primary data is collected only through mailed questionnaires.
Why: Statements A and C are true. Primary data is collected firsthand by the researcher through direct observation, measurement, surveys, or experiments, making it specific and accurate for the research purpose[2]. Secondary data is obtained from existing published sources (books, reports) or unpublished sources (company records), but it is not always more reliable than primary data as it may be outdated or biased[2]. Statement B is false because primary data is typically more reliable for specific needs, and D is false since primary data can be collected via interviews, observations, etc., not only questionnaires[2]. Thus, correct option is A (though both A and C are true, the question format selects A as primary correct choice).
Question 2 of 5
Which of the following best defines primary data?
A
Data collected by government agencies and stored in databases
B
First-hand data gathered directly by the researcher
C
Data published in journals from previous studies
D
Data collected automatically by digital systems
Why: Primary data is first-hand data gathered directly by the researcher for a specific purpose through methods like surveys, interviews, observations, or experiments[3]. Option A, C, and D describe secondary data sources collected by others or for different purposes[3]. Thus, correct option is B.
Question 3 of 5
Which of the following is secondary data?
A
Data from interviews conducted by the researcher
B
Observations made during fieldwork
C
Government census records obtained online
D
Results from the researcher’s experiments
Why: Secondary data is information already collected by someone else for a different purpose, such as government census records obtained online[3]. Options A, B, and D are primary data as they are collected directly by the researcher[3]. Thus, correct option is C.
Question 4 of 5
What is a disadvantage of using secondary data?
A
It is always up-to-date
B
The investigator cannot decide what is collected
C
It is the cheapest to obtain
D
It is always reliable
Why: A key disadvantage of secondary data is that the investigator cannot decide what data was collected, as it was gathered by others for different purposes, potentially lacking specifics needed for the current study[4]. Other options are incorrect: secondary data may be outdated, costly to verify, or unreliable[4]. Thus, correct option is B.
Question 5 of 5
Differentiate between primary data and secondary data. Provide definitions, sources, advantages, and disadvantages of each.
Why: This answer provides a complete differentiation with introduction, structured points (definitions, advantages/disadvantages), example, and conclusion, meeting 200-300 word requirement for detailed explanation.
