Defintions
What is non-experimental research?
Provide an example
research that lacks the manipulation of an independent variable?
non-experimental research is preferred when the research wants to manipulate the independent variable.
Explain why if it is True or False
FALSE
a researcher is looking at the relationship between level of stress and hours of sleep
Correlation
This movie was all about a snail who has dreams of being fast. He wants to be a racer driver. He ends up getting super speed and becomes a racer. The name of the movie is another name for very fast
Turbo
What is correlational research?
Provide an example
the researcher measures two variables with little or no attempt to control extraneous variables and then assesses the relationship between them
Non-experimental approaches only include cross-sectional studies and longitudinal studies.
Explain why if it is True or False
FALSE
Consider a study conducted to understand the similarities or differences between identical twins who are brought up together versus identical twins who were not. The study observes several variables, but the constant is that all the participants have identical twins.
In this case, researchers would want to observe these participants from childhood to adulthood, to understand how growing up in different environments influences traits, habits, and personality.
Longitudinal study
"Though at times it may feel like the sky is falling around you, never give up, for every day is a new day."
Chicken Little
What is a complex correlation?
Provide an example
Complex correlational research involves measuring several variables- either binary or continuous- and then assessing the statistical relationships among them.
Correlational research is high on external validity than experimental research.
Explain why if it is True or False
TRUE
The Big Five personality factors have been identified through ___ (fill in the blank) of people’s scores on a large number of more specific traits.
Factor analysis
In The Matrix, does Neo take the blue pill or the red pill?
Red pill
What are cross-sequential studies?
Provide an example
Combines elements of both cross-sectional and longitudinal studies.
Directionality problem and third-variable problem are two reasons that correlation does not imply causation.
TRUE
Researchers want to understand whether exam performance can be predicted based on revision time, test anxiety, lecture attendance and gender.
Multiple Regression
Who was Anakin Skywalker padawan?
Ahsoka Tano
What is factor analysis?
Provide an example
factor analysis organizes the variables into a smaller number of clusters, such that they are strongly correlated within each cluster but weakly correlated between clusters. Each cluster is then interpreted as multiple measures of the same underlying construct.
Regression is a statistical technique that allows researchers to predict one variable given another.
TRUE
Stanley Milgram found that about two thirds of his research participants were willing to administer dangerous shocks to another person just because they were told to by an authority figure
Observational study
What is the highest-grossing horror movie of all time?
