Practical Research 2 REVIEW QUIZ

Which of the following is an example of a descriptive research question?

• What is the level of awareness of male and female students on their town's cultural heritage?

• Is there a significant difference between the students' level of awareness town's cultural heritage when grouped according to gender?

• Is there a significant relationship between home-school distance and tardiness of the students?

• Based on the result of the study, what program could be developed to enhance the cultural awareness of the respondents?

Answer explanation

The correct choice is a descriptive research question as it seeks to measure the level of awareness among students without comparing or establishing relationships, unlike the other options.

Which of the following is an example of a relationship-based research question?

• What is the level of awareness of male and female students on their town's cultural heritage?

• Is there a significant difference between the students' level of awareness town's cultural heritage when grouped according to gender?

• Is there a significant relationship between home-school distance and tardiness of the students?

• Based on the result of the study, what program could be developed to enhance the cultural awareness of the respondents?

Answer explanation

The correct choice, 'Is there a significant relationship between home-school distance and tardiness of the students?', directly investigates the connection between two variables, making it a relationship-based research question.

A college student is conducting research on study habits and academic success. They plan to focus on methods used during exam preparation. Which is the most suitable research question for their study?

• What methods do college students use to prepare for exams?

• How does using flashcards impact exam scores among college students?

• Why do some college students not prepare well for exams?

• What resources are commonly available for college students during exams?

Answer explanation

The question 'How does using flashcards impact exam scores among college students?' is most suitable as it directly examines the relationship between a specific study method and academic success, aligning with the research focus.

What is the primary purpose of the alternative hypothesis in a research study?

• To establish a baseline for comparison

• To support the null hypothesis

• To propose a specific effect or relationship

• To eliminate the need for statistical testing

Answer explanation

The primary purpose of the alternative hypothesis is to propose a specific effect or relationship that the research aims to investigate, contrasting with the null hypothesis which suggests no effect.

Which statement best describes a Type II error in research hypothesis testing?

• Accepting a false null hypothesis

• Rejecting a true null hypothesis

• Failing to reject a false null hypothesis

• Accepting a true null hypothesis

Answer explanation

A Type II error occurs when researchers fail to reject a false null hypothesis, meaning they incorrectly conclude that there is no effect or difference when one actually exists.

You are conducting research that aims to determine if a new teaching method improves student performance. If you conclude that the new method is effective when, in fact, it has no impact, what type of hypothesis error is committed?

• Type I error

• Type II error

• Alpha error

• Null error

Answer explanation

A Type I error occurs when you reject the null hypothesis (conclude the new method is effective) when it is actually true (the method has no impact). This is also known as an alpha error.

Imagine you are experimenting to test the effect of sunlight on plant growth. What would be an appropriate hypothesis for this study?

• Plants will grow better in the absence of sunlight.

• Plants will show no difference in growth with or without sunlight.

• Plants exposed to sunlight will exhibit increased growth compared to those kept in the dark.

• Plant growth will be stunted in the presence of sunlight.

Answer explanation

The correct hypothesis states that plants exposed to sunlight will grow better than those in the dark, aligning with the known benefits of sunlight for photosynthesis and growth.

While developing your hypothesis, you realize it lacks a clear connection to your research question. What steps should you take to address this issue?

• Revise the research question to match the hypothesis

• Ignore the lack of connection as it is not significant

• Reframe the hypothesis to align with the research question

• Abandon the hypothesis and start anew

Answer explanation

To address the lack of connection, you should reframe the hypothesis to align with the research question. This ensures that your hypothesis is relevant and can be effectively tested in relation to your research objectives.

In this section of research study, the researcher defines who will benefit out of the findings of the study and describe how the problem will be solved.

• Background of the study

• Significance of the study

• Scope and delimitation

• Statement of the problem

Answer explanation

The 'Significance of the study' section identifies who will benefit from the research findings and explains how the identified problem will be addressed, making it the correct choice.

The statement, "The research will educate clients in deciding on whether the industry is really fulfilling its responsibility to the community or is just showing off to promote business", is an example of _________?

• Scope and delimitation

• background of the study

• Hypothesis

• Significance of the study

Answer explanation

The statement highlights the importance of assessing the industry's impact on the community, which aligns with the 'Significance of the study' as it emphasizes the study's relevance and potential contributions.
