D. Historical research
A. Experimental research
This variable represents the outcome that is measured after the independent variable has been introduced.
Dependent variable
These are the individuals selected to provide information or take part in a research investigation.
Participants
In the research process, this step involves making an educated prediction that can be tested through investigation.
Assumption/Hypothesis
A researcher notices that as the number of hours students spend studying increases, their examination scores also increase. Identify the type of relationship shown.
Positive Correlation
A researcher compares the reading performance of two existing Grade 11 sections after using different teaching strategies. The classes were already formed before the study began. What type SPECIFIC type of quantitative research is being used?
A teacher wants to determine whether a newly developed learning module improves students' achievement. Which variable should represent the dependent variable?
A. The learning module
B. The students' achievement scores
C. The number of learners
D. The length of time
B. The students' achievement
Which situation best demonstrates the use of quantitative research?
A. Interviewing students to understand how they feel about distance learning experiences.
B. Counting the number of students who passed the quarterly Mathematics examination.
C. Observing teachers' classroom behavior and organizing responses into common themes.
D. Recording detailed personal stories shared by participants during individual interviews.
B. Counting the number of students who passed the quarterly Mathematics examination.
C. Identify the research problem and determine the purpose of the investigation.
C. True experimental research
A researcher finds that increasing classroom temperature does not consistently affect students' spelling scores. Which conclusion is most appropriate?
A. The variables demonstrate a positive correlation throughout the research investigation.
B. The variables demonstrate a negative correlation during the entire research procedure.
C. The variables demonstrate no correlation based on the available research findings.
D. The variables demonstrate experimental control because participants were randomly assigned.
C. The variables demonstrate no correlation based on the available research findings.
Which statement best explains why random assignment is important in true experimental research?
A. It prevents researchers from measuring the dependent variable after the intervention.
B. It allows researchers to summarize characteristics of only one measurable variable.
C. It enables investigators to collect opinions using detailed interviews and observations.
D. It helps ensure research groups are comparable before the treatment is introduced.
D. It helps ensure research groups are comparable before the treatment is introduced.
Which sequence correctly represents the research process from beginning to end?

B. Observation → Hypothesis → Results → Question → Conclusion
C. Observation → Question → Hypothesis → Results → Conclusion
D. Observation → Results → Question → Hypothesis → Conclusion
C. Observation → Question → Hypothesis → Results → Conclusion
Which action demonstrates the main purpose of descriptive research?
A. Determining whether a treatment causes significant changes in students' performance.
B. Examining whether two measurable variables influence each other statistically.
C. Stating the existing characteristics of a population without introducing treatments.
D. Exploring participants' personal experiences through interviews and observations only.
C. Stating the existing characteristics of a population without introducing treatments.
A teacher randomly assigns students into two groups before introducing two different teaching methods. Why is random assignment important in this situation?
A. It increases the likelihood that the groups are comparable before the treatment begins.
B. It allows the researcher to collect detailed opinions from every participant involved.
C. It guarantees that every participant will obtain similar scores after the intervention.
D. It eliminates the need to identify independent and dependent research variables.
A. It increases the likelihood that the groups are comparable before the treatment begins.
A researcher investigates the relationship between students' attendance and examination scores. Which statement best explains why this study is not experimental?
A. The researcher summarizes only one variable without collecting numerical information.
B. The researcher observes existing variables without introducing or manipulating treatments.
C. The researcher interviews participants instead of collecting measurable numerical evidence.
D. The researcher randomly assigns participants into treatment and comparison groups.
B. The researcher observes existing variables without introducing or manipulating treatments.
Which statement best distinguishes true experimental research from quasi-experimental research?
A. True experimental research examines relationships, whereas quasi-experimental research summarizes populations.
B. True experimental research describes characteristics, whereas quasi-experimental research measures opinions.
C. True experimental research uses interviews, whereas quasi-experimental research uses questionnaires.
D. True experimental research uses random assignment, whereas quasi-experimental research does not.
D. True experimental research uses random assignment, whereas quasi-experimental research does not.
A researcher discovers that as students' daily reading time increases, their vocabulary test scores also increase. Statistical analysis shows that both variables consistently move in the same direction. Identify the type of correlation.
Positive Correlation
A researcher observes that students' favorite music genre has no measurable relationship with their final grades. Statistical analysis confirms that changes in one variable do not correspond to changes in the other. Identify the type of correlation.
No correlation
A researcher wants to determine the average number of hours Grade 12 students spend studying each night. The study only describes the existing situation without examining relationships or applying treatments.
Descriptive Research
During the research process, a researcher has already made observations and developed a research question. The researcher now writes a tentative answer that will later be tested through data collection and analysis. What step of the research process is being performed?
Assumption or Hypothesis
A researcher measures students' critical thinking skills before implementing a problem-based learning strategy. After six weeks, the same students take another assessment to determine whether their performance has changed. Which SPECIFIC experimental design is illustrated?
