test a specific hypothesis with reality
Descriptive Research
small snapshot - center tendencies
Correlational Research
associations and relationship
Quasi-Experimental
Has and intervention, non random group
Classical Experimental Research
Has an intervention, randomized group
Autonomy
Independence - freedom to decide
Non-Malfeasance
Do no harm to participants
Justice
Fairness
Truth
Failing to disclose all information
Confidentiality
Privacy
Beneficence
Benefits outweigh the risks
Action Research
requires immediate response
Case Study
examine specific, small group - qualitative
Casual design
We have X, therefore what is Y?
Observational
eyes as the research tool, people change behavior
Cohort
Multiple case studies
Cross-Sectional
snapshot of what is going on
Meta-analysis
Summary reports that collect or combine multiple studies on a single topic
Experimental
Include Intervention & examine the degree of change
Exploratory
no existing literature on the topic
Historical
study of events over time
Longitudinal
variables over time
Research Order
Idea - lit review - purpose - RQ - methodology - variables, research type - research design - statistical analysis
Random Sampling
tables of random numbers
Stratified random sampling
dividing into groups before random sampling
Systematic sampling
every 10th, 100th person, phone book
random assignment
names in a hat
post hoc
generalizable
Central tendency scores
mean, median, mode
Variability scores
SD, range of scores
Parametric
Normal distribution, equal variances, independent observations
Nonparametric
distribution is not normal, outliers
Normal curve
skewness (direction), kurtosis (vertical)
Assumptions of parametric test
-the population is normally distributed
-samples have the same variances
-observations are independent
Interrater reliability
degree to which different testers can obtain the same scores on the same participants
Test-retest method
determining stability in which a test is given one day and then administered exactly as before
Pearson correlation
measure of the linear dependence between X and Y
Partial correlation
measuring R between two variables, controlling one or more variables
Semi partial correlation
measuring R between two variables, controlling only one aspect of one variable
Dependent t-test
test the same group at two different times
Independent t-test
Test the difference between two different groups at a single trial
Analysis of Variance (ANOVA)
test differences between two or more means
MANOVA
ANOVA with several dependent variables
