Who are the key contributors to the development of Hypothesis Testing?
Ronald Fisher, Jerzy Neyman, Karl Pearson, Egon Pearson
Charles Darwin, Gregor Mendel, Francis Galton
Albert Einstein, Isaac Newton, Galileo Galilei
Aristotle, Plato, Socrates
What is the first step in the hypothesis testing process?
Calculate the p-value
Formulate the null and alternative hypotheses
Identify the test statistic
Compare with alpha value
In hypothesis testing, the null hypothesis (H0) usually assumes that:
The effect is real
The observations are due to pure chance
The sample is biased
The population is infinite
Which variable is manipulated by the researcher in an experiment?
Dependent variable
Independent variable
Control variable
Random variable
Which type of variable is measured in an experiment as the outcome?
Independent variable
Dependent variable
Nominal variable
Ordinal variable
Nominal measurement involves:
Categories with no order
Ordered categories without equal intervals
Scores with equal intervals
Continuous data
Ordinal measurement involves:
Categories with distinct order
Categories without order
Scores with equal intervals
Continuous logical sequence
Metric measurement includes:
Discrete categories
Ordered categories without equal intervals
Real numbers with equal intervals
Random assignments
What is the first phase of data analysis?
Analysis
Quality Measurement
Data Cleaning
Quality Analysis
Which of the following is NOT part of the phases of data analysis?
Data Cleaning
Quality Analysis
Hypothesis Generation
Quality of Measurement
Ethnographic analysis focuses on:
Testing statistical models
Direct study of individuals and cultures
Comparing different datasets
Analyzing numbers and percentages
Narrative analysis is mainly used to analyze:
Experiments
Text or visual data
Numbers and frequencies
Statistical errors
Phenomenological analysis is based on:
Cultural studies
Direct sense perception and experiences
Comparing quantitative data
Interpretation of documents
Which analysis is based on categorizing and comparing qualitative data?
Narrative Analysis
Constant Comparative Analysis
Grounded Theory Analysis
Content Analysis
Hermeneutic analysis emphasizes:
Quantitative data collection
Objectivity and interpretation freedom
Laboratory experimentation
Mathematical modeling
Grounded theory analysis involves:
Developing hypotheses after data collection
Using pre-existing theories
Focusing only on cultural studies
Analyzing numerical data
What is the recommended minimum sample size according to most statisticians?
50
75
100
200
Random assignment is used to:
Select participants from the population
Measure dependent variables
Create groups of like-minded participants
Control confounding variables
Which type of experimental design uses different samples for each phase?
Repeated measures
Matched pairs
Individual tests
Narrative analysis
In repeated measures design, participants:
Are assigned to only one condition
Participate in all conditions of the experiment
Are randomly selected but not measured
Are only used in control groups
