Exam 1 Flashcards
What are the six steps of the scientific method?
question, hypothesis, test, results, conclusions, share
What are the five main research designs?
observational research, case studies, surveys, correlational designs, and experiments
What two forms can research take?
quantitative and qualitative
What is quantitative research?
focuses on numbers
What is qualitative research?
focuses on words
Psychology focuses on what form of research?
quantitative research
What is naturalistic observation?
research that studies human or animal behavior in its natural environment
What is structured observation?
researchers observe people or animals in a lab setting
What is an advantage of structured observation?
the experimenter can for more extraneous variables and save time
What are case studies?
research on one person or a small group based on careful observation
What’s an advantage of case studies?
you receive a good description of the behavior being investigated in one or two individuals
What’s a disadvantage of case studies?
what you’re learning may be unrepresentative of the larger population, which makes it lack generalizability
What is a survey?
a questionnaire consisting of at least one scale with some number of questions to assess a psychological construct of interest
What is correlational research?
examining the relationship between two variables or two groups of variables
What is a correlational coefficient?
the strength of a relationship measured numerically
What does it mean if a correlational coefficient is -1.00?
as one variable goes up the other goes down
What does it mean if a correlational coefficient is 0?
there is no relationship at all
What does it mean if a correlational coefficient is +1.00?
as one variable goes up or down, so does the other = a perfect relationship
What is an experiment?
a controlled test of a hypothesis in which a researcher manipulates one variable and measures its effects on another variable
What is an independent variable?
the variable that is manipulated
What is a dependent variable?
the variable that is measured
What is a control group?
a group that is not manipulated
What is an experimental group?
a group that is manipulated
What is random assignment?
participants have an equal chance of being in the control or experimental group
What is multi-method research?
employing several research approaches at different stages of the research process
What is a meta-analysis?
a statistical procedure that allows a researcher to combine data from more than one study
What is reliability?
describes how consistent a measure is
