Practical Research 2 Review Exam Q1

A political scientist collects data from 1,000 Filipino respondents to analyze the factors that influence voting behavior in national elections. How does the large sample size benefit the study in terms of quantitative research characteristics?

• It increases the study's subjectivity

• It ensures that the findings can be generalized to the larger Filipino voting population

• It makes the study more flexible and adaptable to changing political trends

• It reduces the time required for data analysis

Researchers are studying the relationship between social media use and mental health among teenagers. They gather data by surveying a large group of participants and analyzing the responses using statistical methods. How does the objectivity of this study contribute to the credibility of the results?

• It allows the researcher's personal opinions to guide the interpretation of data

• It ensures that the data is analyzed without bias or personal influence

• It increases the flexibility of research methods

• It allows for the exploration of complex, subjective experiences

A researcher conducts a study to compare the effectiveness of three different learning strategies on students' problem-solving skills. The students are divided into three groups, and their problem-solving abilities are measured before and after the intervention. Why is this study an example of a quasi-experimental design?

• It uses random assignment to groups

• It measures cause and effect but lacks random assignment

• It describes students' problem-solving skills without intervention

• It focuses on collecting qualitative data about learning experiences

A study compares the effects of modular learning and online learning on students' academic performance in rural and urban settings. Data is collected using standardized tests and statistical software is used for analysis. Why might this quantitative approach be limited in providing a comprehensive understanding of the students' learning experiences?

• It captures in-depth emotional responses and personal experiences

• It focuses on numerical data, which may not fully explain students' learning experiences

• It allows for flexible research design adjustments during the study

• It uses small sample sizes to ensure detailed case studies

A study investigates how TikTok usage influences the academic performance of Filipino high school students. Researchers collect data on screen time and grades from 1,000 students to analyze any potential correlations. Why is quantitative research important in this study?

• It provides a deep understanding of students' personal experiences with social media

• It allows for the measurement and analysis of the relationship between social media usage and academic performance

• It captures the qualitative aspects of students' engagement with TikTok

• It enables the researchers to adjust their study approach based on students' feedback

A researcher examines the impact of AI-driven educational tools on student engagement and performance in STEM subjects. The study involves analyzing test scores and engagement metrics from 800 students. Why is quantitative research significant in this field?

• It helps the researcher understand the qualitative impacts of AI on students' attitudes towards learning

• It allows the researcher to modify the study design based on initial findings

• It offers insights into students' personal experiences with AI-driven learning

• It provides measurable data on the effectiveness of AI tools in improving engagement and performance

After a recent natural disaster, an NGO collects data on the number of affected households in different regions to prioritize relief efforts. How does quantitative research aid in this decision-making process?

• It provides detailed stories about individual households' experiences

• It helps the NGO allocate resources based on accurate, measurable data

• It offers the flexibility to change relief strategies based on feedback

• It captures the emotional impact of the disaster on families

A researcher surveys Gen Z students about their preferred social media platforms. The survey includes options like TikTok, Instagram, and Facebook. Which type of variable is represented by the choices given for this survey?

• Discrete Variable

• Nominal Variable

• Ordinal Variable

• Dichotomous Variable

A research project investigates the impact of various social media usage levels (low, moderate, high) on academic performance among Filipino Gen Z students. How does the level of social media usage function in this research?

• It is a Nominal Variable since it categorizes students into distinct groups

• It is an Ordinal Variable as it ranks students based on usage levels

• It is a Dichotomous Variable as it only distinguishes between two types of usage

• It is a Continuous Variable as it allows for fractional values

A psychologist studies the relationship between social media usage and self-esteem among students, collecting data on social media habits and self-esteem scores. What type of variable is self-esteem in this research?

• Predictor Variable used to foresee the impact of social media habits

• Control Variable that remains constant to focus on social media habits

• Criterion Variable that is being predicted based on social media habits

• Moderator Variable that adjusts the strength of the relationship between social media and self-esteem
