Types of Quanti Research Flashcards
(20 cards)
What is quantitative research?
Quantitative research is a systematic investigation that primarily focuses on quantifying relationships, behaviors, phenomena, and patterns using statistical, mathematical, or computational techniques.
True or False: Qualitative research is a type of quantitative research.
False
Name one type of quantitative research design.
Descriptive research, correlational research, experimental research, or causal-comparative research.
What is the main purpose of descriptive research?
The main purpose of descriptive research is to provide a detailed account of a phenomenon or population without manipulating variables.
Fill in the blank: In correlational research, researchers examine the ______ between two or more variables.
relationship
What distinguishes experimental research from other types of quantitative research?
Experimental research involves the manipulation of one or more independent variables to observe their effect on a dependent variable.
What are independent variables?
Independent variables are variables that are manipulated or controlled in an experiment to test their effect on dependent variables.
What are dependent variables?
Dependent variables are the outcomes or responses that are measured in an experiment to assess the effect of independent variables.
Multiple Choice: Which of the following is NOT a type of variable in quantitative research? A) Independent B) Dependent C) Confounding D) Qualitative
D) Qualitative
True or False: A confounding variable can affect the relationship between the independent and dependent variables.
True
What is a control variable?
A control variable is a variable that is kept constant to prevent it from influencing the outcome of an experiment.
Fill in the blank: In a study, the variable that researchers manipulate is called the ______ variable.
independent
What is the role of a sample in quantitative research?
A sample is a subset of a population used to draw conclusions about the entire population.
What is a hypothesis in quantitative research?
A hypothesis is a testable prediction about the relationship between two or more variables.
Multiple Choice: Which of the following is a characteristic of quantitative research? A) Subjective analysis B) Use of numerical data C) Open-ended questions D) Narrative descriptions
B) Use of numerical data
True or False: Random sampling helps to reduce bias in quantitative research.
True
What is the difference between a population and a sample?
A population is the entire group of individuals or instances about whom we hope to learn, while a sample is a smaller group selected from the population.
What is the purpose of data analysis in quantitative research?
The purpose of data analysis is to interpret and summarize numerical data to draw conclusions and make inferences.
Fill in the blank: In quantitative research, a variable that can take on multiple values is called a ______ variable.
continuous
