What is a hypothesis?
A testable statement about how two or more variables are expected to relate to one another aka making predictions about the explanatory/explained variable.
What would your IV be referred to if you could not manipulate it?
An assigned or subject variable.
When you run observational research, you can only establish what type of relationship?
A predictive relationship.
When can you say your research is valid?
When it measures what it is intended to measure.
You can say the IV may have caused a difference in the DV when you have a non-chance difference aka? (I think she explained this, but essentially you can naturally expect a difference between the two groups, but the difference must be non-chance)
Cause of the change, that can be manipulated or observed.
What is the Independent variable.
If you have an assigned/subject IV and are solely collecting data, what type of research would you be conducting?
Observational research.
When doing experimental research to see a change, you would need to _____ your subjects to the independent variable.
What is expose?
If you can say that the IV actually did cause a change in the DV aka the conclusion that you have drawn from your experiment accurately reflects what has gone in the experiment, you would have what type of validity?
What is internal validity?
What type of experimental design is conducted via a control group and external group, given both a post-test, but neither groups are given a pre-test?
What is a post-test only design?
Variable that is related to, or caused by, shifts/changes in the explanatory variable.
These three criteria:
1. the two variables precede one another in time.
2. the two variables are synchronized.
3. no other outside influence/variable can be involved between the two stated/studied variables
Are all what makes up the definition of?
What is causation.
You are doing experimental research, you exposed your subjects to the independent variable, what are you going to do next?
What is Measure what happens to the dependent variable.
What type of group is used to increase internal validity, known as the comparison group, and is not exposed to the IV.
What type of validity refers to how applicable the findings are to other people, situations, and/or settings.
If you have control of the independent variable(IV), then you can refer to that IV as being...
A Manipulated variable
Which type of research is most likely to find relationships to meet the 3 criteria needed to determine causation?
What type of experimental design would you be running if you test your subjects before they are exposed to the IV, and then once exposed to the IV, re-measured/re-tested to see the change?
Which group is exposed to the IV, the control or external group?
What is the external group?
Since it is often difficult to select subjects via random selection, we would assign the available subjects randomly to either the control or experimental group. This type of assignment is referred to as?
What is randomized assignment?
When you aka the researcher can/does manipulate the independent variable, then the type of research you are doing would be?
What is Experimental Research.
What type of research can you solely determine causation with caution?
What type of variable(s) along with the independent variable affect the dependent variable, but are deemed extraneous.
What type of experimental design is also known as the classical experiment?
What is the pre-test and post-test with control group design.
When doing a experimental research, and you manipulate the IV but do not randomly assign your subjects to the control/experimental groups, you would actually be running what type of experiment?
What is a quasi experiment?
