Quantitative #1
What is survey research?
collect information from a group of people through questionnaires and/or survey.
What is quantitative research?
a systematic investigation that focuses on collecting and analyzing numerical data to identify patterns, relationships, or trends.
It is also known as extraneous variable.
Cofounding Variable
Provide the four measurements of variables?
Nominal, Ordinal, Ratio, Interval
What is nominal variable?
represents categories with no inherent order or ranking.
Which of the following best describes a limitation of this approach related to the quantifiability of the data?
A. The numerical data will be too difficult to analyze and interpret statistically.
B. Students may struggle to choose a response that fully reflects their unique personal experiences.
C. The use of ratings will lead to biased results that cannot be replicated.
D. This method will prevent the researcher from reaching a large number of participants.
B. Students may struggle to choose a response that fully reflects their unique personal experiences.
Which of the following is the most important condition for achieving generalizability?
A. Conducting in-depth interviews with participants
B. Using a large, randomly selected sample from the target population
C. Measuring only variables that are easy to quantify
D. Ensuring all participants provide complete responses to every question
B. Using a large, randomly selected sample from the target population
What is the difference between I.V and D.V?
Control and Effect, Cause and Effect
I.V- Manipulation
D.V- No manipulation
What is an interval variable?
has ordered categories and equal intervals between them, but it doesn't have a true zero point.
What is the difference between true experimental and quasi-experimental?
True experimental- Random, non-bias
Quasi-Experimental - non-random, bias
Identify the type of quantitative research use.
A psychology teacher investigates whether there is a relationship between screen time and sleep quality among high school students. The researcher collects numerical data on both variables and uses statistical analysis to determine if they are related.
Correlational
Identify the type of quantitative research use.
A study compares the stress levels of working and non-working students to see if employment status affects academic stress. The researcher did not manipulate the groups—they already exist.
Causal-comparative (Ex post facto)
Identify the I.V and D.V
"An Investigative Analysis of the Efficacy of Gamification Modalities in Digital Learning Platforms on the Academic Achievement Metrics Among Senior High School Science Cohorts"
Independent Variable (I.V.):
Gamification modalities in digital learning platforms
Dependent Variable (D.V.):
Academic achievement metrics in science
A fitness coach measures the weight in kilograms of athletes before and after a training program.
Ratio
Identify the measurement of variable use in the scenario.
During a school health screening, the nurse records the blood type of each student. The results are later analyzed by a biology class for a genetics project. The recorded types include: A, B, AB, and O.
Nominal
Identify the type of quantitative research use.
A national education agency sends out a structured questionnaire to teachers across the country to gather their opinions about the effectiveness of distance learning.
Survey
Identify the type of quantitative research use.
A researcher wants to know the preferred learning styles of Grade 12 students. They distribute questionnaires and summarize the results in charts, without analyzing relationships or causes.
Descriptive
Identify the I.V and D.V
"The Quantitative Assessment of Instructor Feedback Frequencies and Their Effect on the Cognitive and Behavioral Engagement of Students in Virtual Higher Education Environments"
Independent Variable (I.V.):
Instructor feedback frequencies
Dependent Variable (D.V.):
Cognitive and behavioral student engagement
Identify the measurement of variable use in the scenario.
A customer satisfaction survey asks participants to rate their satisfaction on a scale from 1 to 5, where 1 means “Very Unsatisfied” and 5 means “Very Satisfied.”
Ordinal
Identify the I.V and D.V
A health class tests if drinking sugary drinks affects student energy. One group drinks water, the second group drinks one sugary drink, and the third group drinks two sugary drinks before a simple physical activity test. Then, they measure how long each student can do jumping jacks.
Independent Variable: Number of sugary drinks consumed
Dependent Variable: Duration of physical activity (energy level)
Identify the type of quantitative research use.
A group of researchers randomly selects participants and randomly assigns them into two groups: one group receives a specific training program, and the other does not. After the training, both groups are tested to evaluate the program’s effect.
True Experimental
Identify the type of quantitative research use.
To evaluate the effect of a new math curriculum, a school uses two classes already formed by the registrar—one receives the new curriculum, and the other receives the standard. Test scores are compared after one month.
Quasi-Experimental
Identify the I.V and D.V
"A Quasi-Experimental Study on the Impact of Blended Learning Approach and Study Habits on the Academic Achievement of STEM Senior High School Students in Mathematics"
Independent Variables (I.V.):
Blended learning approach
Study habits
Dependent Variable (D.V.):
Academic achievement in Mathematics
A historian notes the years in which major historical events occurred to analyze the frequency of wars over centuries.
Interval
Identify the measurement of variable use in the scenario.
In an annual performance appraisal, employees are assessed in various categories such as punctuality, teamwork, communication skills, and productivity. Each is scored on a percentage scale from 0 to 100. HR uses these scores to determine eligibility for bonuses and promotions. Scores are also compared across departments to identify training needs.
