When to do a Power Analysis?
,Give this one a try later!
When planning the study (before)
- to determine the smallest sample size needed to obtain a predetermined
level of power
When the study is completed (after)
- to determine the level of power actually achieved in a particular study
(done to help explain your results)
Define external validity
Give this one a try later!
External validity refers to the degree to which the results of a study can be
generalized to and across people, settings, and times.
Generalize to:
1. different people
2. different settings
3. across time
Define parameter. What is a Parameter = equal to
Give this one a try later!
A numerical measure of a characteristic of the POPULATION
Remember P for parameter & population
Ex. the population of the 750 pennies in a jar is the parameter
,Types of Probability (Random) Sampling
Give this one a try later!
Simple random
Stratified random
Multistage (cluster)
Systematic
What are the 7 levels of evidence
Give this one a try later!
Level 1: Meta-analysis, systematic review
Level 2: At least one randomized control trial
Level 3: Quasi-experimental study
Level 4: Non-experimental study
Level 5: Systematic Review of descriptive or qualitative studies
Level 6: A single descriptive or qualitative study
Level 7: Opinion of authorities or expert committee reports
Explain a Quantitative paradigm
Give this one a try later!
Focuses on what can be measured: objective reality (numbers, specific
values)
Involves collecting and analyzing data (numeric)
Deductive reasoning (big to small)
, Focus is reductionistic (breaking concepts down into smaller ideas)
Researcher is neutral (researcher is independent from those being studied)
= it TESTS a theory
How can maturation threaten internal validity
Give this one a try later!
Developmental, biological, psychological processes that operate within an
individual as a function of time and are external to the events of the
investigation
Ex. The performance of man running begins decreasing after 15 minutes
because of fatigue.
Decrease threat: completing experiment in as short of a time frame as
feasible.
Define paradigm
Give this one a try later!
Defined as a way of thinking about the world: A worldview
Divided into: quantitative and qualitative paradigms
Explain: Random selection vs. Random Assignment
