What school of thought is based on introspection?
what is structuralism
A precise description of how variables in study are manipulated and/or
measured
What is an operational definition of a variable?
True or false: correlation equals causation
False, Correlation does not equal causation due to possibility of cofounding variables. (ex. ice cream sales and number of shark attacks)
when the study is actually measuring what it intends to measure
What is validity?
an explanation or model for something
what is a theory?
A study where neither participants or experimenters know what groups they are assigned
What is Double blind?
2 things an experiment must have
1. Manipulation of IV
2. Random assignment
3. Random sampling (optional but good)
doing something in a reasonable way that takes away bias.

The whole is more than the sum of its parts
what is the Gestalt Theory

What is descriptive research?
the variable that change happens as a result of the manipulation in the independent variable
What is the dependent variable?
The extent to which a study is consistent with and produces the same results every time.
what is reliability?
a tentative and testable statement about the relationship between two or more
variables. AKA a prediction
what is a hypothesis
Tests if a relationship exists between 2 or more variables, what direction, and how strong the relationship is but non-experimental
what is Correlational research?
Variable that is being manipulated/changed between groups/conditions
what is the independent variable?
a number indicating magnitude and direction of the correlation between -1 and 1.
What is a correlation coefficient?
something that varies and can be measured
What is a variable?
Tests hypothesis to determine cause and effect relationships
What is experimental research?
Participants are unaware of what group they are in
an agreed measure on how to classify and record observed events and counter observer bias in research.
what is inter-rater reliability?
