SIMULADOR QUANTITATIVE

Which statement correctly distinguishes qualitative from quantitative research?. Qualitative research does not involve interviews. Both types are identical in design and tools. Quantitative research excludes statistics. Qualitative research focuses on rich verbal descriptions, while quantitative research analyzes numerical data.

What should a researcher do when analyzing and interpreting data?. Generalize findings to all populations. Summarize findings using visuals and justify interpretations clearly. Rely solely on personal intuition. Present results without explaining their significance.

What is a key purpose of conducting a literature review in applied linguistics?. To copy previously used research instruments. To evaluate existing methods and identify key contributors. To fill space in the research report. To avoid formulating original hypotheses.

How does quasi-experimental research differ from true experimental design?. Participants are not randomly assigned in quasi-experimental studies. It rejects causal relationships. It is only used in laboratory settings. It requires post-tests but not pre-tests.

What role does a research paradigm play in the research process?. It defines the participants' roles in the study. It is used only to choose research instruments. It is useful only for qualitative research. It provides a philosophical framework that guides beliefs and actions.

A researcher finds that the collected data are not normally distributed. Which decision is the most appropriate?. Always use ANOVA because it is the strongest statistical procedure. Transform every variable until it fits a normal distribution. Ignore the distribution because all statistical tests produce equivalent results. Use a non-parametric test because it does not require normal distribution assumptions.

Which situation best justifies including an open-ended question in a questionnaire?. When the researcher wants respondents to express ideas that may not fit predefined categories. When every participant must choose exactly one predefined option. When the study requires the fastest possible statistical processing only. When responses must be coded automatically without interpretation.

An EFL researcher wants to investigate students' perceptions of gamification. Before writing any questionnaire items, which action would most strengthen the quality of the instrument according to the questionnaire design process?. Prepare graphs for the results before collecting responses. Choose the statistical test before identifying the participants. Write as many questions as possible to increase reliability. Define the information required and the target respondents before drafting items.

Why should questionnaire items generally progress from easier to more complex questions?. To ensure that demographic questions are always answered last. To guide respondents naturally and reduce confusion or bias. To shorten the questionnaire regardless of quality. To encourage respondents to skip difficult questions.

Which of the following best describes a complete research report?. It is written with a specific audience in mind and structured accordingly. It is the same for academic and general readers. It includes only data tables and graphs. It avoids mentioning limitations to appear objective.

Which type of knowledge is least suitable for conducting objective educational research?. Intuitive knowledge. Authoritarian knowledge. Logical knowledge. Empirical knowledge.

What is a key implication of epistemology for applied linguistics research?. It focuses solely on philosophical debates unrelated to data. It restricts researchers to only one type of data.

Which of the following is a benefit of conducting quantitative research remotely?. It removes the need for ethical approval. It allows anonymity and broad participation. It prevents technical errors. It is suitable only for qualitative studies.

What is a distinctive feature of true experimental design?. Participants are randomly assigned to groups. It avoids statistical analysis. It uses interviews and observations. It requires participants to choose their group.

Why are structured interviews especially appropriate in quantitative research?. Because every participant receives the same questions in the same order, improving comparability. Because researchers avoid recording responses until after the interview. Because participants are expected to elaborate long personal narratives. Because interviewers may freely adapt questions during each interview.

A multiple-response item asks about teaching strategies but does not indicate how many options participants may select. What is the best improvement?.

An EFL teacher introduces a new teaching strategy to one class while another class continues with regular instruction. What is the primary purpose of the second class?. To validate the wording of the survey. To serve as the control group for comparison. To increase the questionnaire response rate. To replace the experimental treatment if needed.

Which ethical consideration is most important when collecting data from participants?. Sharing raw data online for transparency. Securing informed consent. Assuming verbal agreement is enough. Avoiding all interaction with participants.

How does Clifford Woody's definition of research challenge the idea that research is merely about collecting data?. It suggests research is mainly a technical process. It focuses only on gathering data from multiple sources. It limits research to social sciences only. It emphasizes defining problems, forming hypotheses, and making conclusions, not just collecting data.

How can qualitative and quantitative methods complement each other?. By using qualitative insights to interpret statistical results. By avoiding experimental methods. By excluding numerical data to maintain objectivity. By treating both approaches as identical.

Why is quantitative research often seen as objective and scientific?. Because it relies on statistical analysis based on mathematical principles. Because it uses only written descriptions. Because it allows researchers to ignore bias. Because it avoids hypotheses.
