💡 Lời giải chi tiết:
According to general marketing research principles, defining the problem is the first and most vital step because a mistake here will lead to flawed results throughout the project. Kết luận Lý giải: Problem definition
Câu 2:Which type of research design is primarily used to provide insights and an understanding of a problem that is not clearly defined?
💡 Lời giải chi tiết:
Exploratory research is characterized by its flexible and unstructured approach to help researchers gain initial insights into a loosely defined situation. Kết luận Lý giải: Exploratory research
Câu 3:What is the primary advantage of using secondary data over primary data in marketing research?
💡 Lời giải chi tiết:
In marketing research analysis, secondary data is valued for its efficiency because it has already been collected for another purpose and is readily available at a lower cost. Kết luận Lý giải: It is typically less expensive and faster to collect
Câu 4:Which qualitative research technique involves a trained moderator leading a small group of participants in an unstructured discussion?
💡 Lời giải chi tiết:
According to common research practices, a focus group is a qualitative method designed to gather diverse opinions through group interaction guided by a moderator. Kết luận Lý giải: Focus group
Câu 5:Which measurement scale is used purely for labeling or categorizing variables without any quantitative value or order?
💡 Lời giải chi tiết:
According to Stevens' typology of scales, a nominal scale is the simplest level of measurement used only to identify or classify objects into groups. Kết luận Lý giải: Nominal scale
Câu 6:Likert scale typically asks respondents to indicate their level of agreement with a statement using which type of format?
💡 Lời giải chi tiết:

Câu 7:What type of sampling technique involves dividing the population into homogeneous subgroups and then taking a random sample from each group?
💡 Lời giải chi tiết:
According to statistical theory, stratified sampling ensures that specific segments of a population are adequately represented in the total sample. Kết luận Lý giải: Stratified sampling
Câu 8:In causal research, the factor that is manipulated by the researcher to observe its effect on another variable is called the:
💡 Lời giải chi tiết:
In experimental design, the independent variable is the presumed cause that the researcher changes to measure outcomes. Kết luận Lý giải: Independent variable
Câu 9:Which error occurs when the people who choose not to participate in a survey have significantly different characteristics than those who do?
💡 Lời giải chi tiết:
According to survey methodology, non-response error creates a bias when the missing data from non-participants leads to unrepresentative results. Kết luận Lý giải: Non-response error
Câu 10:What is the term for the list of all members of the target population from which the sample will be drawn?
💡 Lời giải chi tiết:
A sampling frame is a physical or conceptual list of the population that provides the basis for selecting sample units. Kết luận Lý giải: Sampling frame
Câu 11:Which research design involves a fixed sample of population elements that is measured repeatedly over a period of time?
💡 Lời giải chi tiết:
Longitudinal research is distinct for tracking the same subjects over time to observe changes in behavior or attitudes. Kết luận Lý giải: Longitudinal research
Câu 12:What is the purpose of using projective techniques in qualitative marketing research?
💡 Lời giải chi tiết:
Projective techniques use ambiguous stimuli to help participants project their deep-seated beliefs and motivations that might not surface in direct questioning. Kết luận Lý giải: To reveal hidden or subconscious feelings that respondents cannot express directly
Câu 13:Which of the following is an example of non-probability sampling?
💡 Lời giải chi tiết:
According to sampling theory, quota sampling is non-random because it relies on the researcher's judgment to fill pre-defined categories. Kết luận Lý giải: Quota sampling
Câu 14:The degree to which a measurement scale produces consistent results when repeated measurements are made is known as:
💡 Lời giải chi tiết:
In measurement theory, reliability refers to the stability and consistency of the scores obtained from a test or scale. Kết luận Lý giải: Reliability
Câu 15:In statistical testing, what does the null hypothesis (H0) generally assume?
💡 Lời giải chi tiết:
The null hypothesis is the default position that assumes any observed effect is due to chance rather than a real relationship. Kết luận Lý giải: There is no significant relationship or difference between variables
Câu 16:What is the main characteristic of a ratio scale that distinguishes it from an interval scale?
💡 Lời giải chi tiết:
According to the hierarchy of scales, only a ratio scale has a true zero point, which allows for the comparison of absolute magnitudes. Kết luận Lý giải: It has an absolute or true zero point
Câu 17:Which observational research method involves researchers living with or observing a cultural group in their natural environment?
💡 Lời giải chi tiết:
Ethnographic research is an immersive qualitative method used to understand behavior through direct participation and observation in real-life contexts. Kết luận Lý giải: Ethnographic research
Câu 18:What does a 'p-value' of 0.03 typically indicate in a marketing research hypothesis test at a 95% confidence level?
💡 Lời giải chi tiết:
According to standard statistical practice, a p-value less than the alpha level of 0.05 indicates that the null hypothesis should be rejected in favor of significance. Kết luận Lý giải: The result is statistically significant
Câu 19:Which term describes a system of people, equipment, and procedures to gather, sort, analyze, and distribute timely information to marketing decision makers?
