Study Methods Flashcards
Experimental Group
The subjects in an experiment who are exposed to treatment (IV)
Control Group
The group of tested subjects left untreated to some procedures (results are compared to those of the experimental group). They are not exposed to the IV.
-> Provide a basis for comparison
Placebo
Treatment / substance designed to have no real effect.
Single Blind Testing
Only the participants are unaware of what consisting they are in and what the premise of the study is
Double Blind Testing
Both the participants and the researcher interacting with them are unaware of what condition participants are in
Randomization
Research participants are assigned by chance rather than choice (using a random generator or hat) to avoid bias.
Discuss the importance of study design
Without a good study design an experiment cannot be repeated or used as a reliable data source.
Specificity
Fitness tests must asses an individuals fitness of the activity or sport in question (running endurance tests will not provide relevant data on a cyclist’s improvement)
Accuracy
The degree to which a measurement represents the true value of something (accuracy of measuring equipment - calibration, type, training of helpers)
Reliability
The degree to which a measure would produce the same result multiple times
Inter-researcher reliability
Whether different researchers in the same situation get similar results
Validity
Fitness tests must measure the component of fitness they are supposed to (putting a cyclist on a bike is specific but making him ride fast for a short amount of time does not test for endurance)
Outline the importance of the PAR-Q
The PAR-Q is a one-page form designed to see if a person should check in with their doctor before becoming much more physically active.
When it is used: Before a physical test (health risks)
What if someone answers yes?
They will have to see a doctor before performing any tests or playing sports / joining clubs
Evaluate field tests
Def. Any test outside of a laboratory
Advantages: Equipment is easy to get, participants can be observed without them knowing
Disadvantages: Less accurate and reliable, many variables that are unwanted
Evaluate laboratory tests
Def. Any test carried out in a laboratory
Advantages: more accurate, more variables can be controlled
Disadvantages: More difficult to access labs and equipment, may lead to a lack of external validity
