Observing something without manipulating any variables

Studying 1 person
Not generalizable
Case study
Combines results of multiple studies to identify overall trends or effects
Meta-Analysis
Examines the relationship between 2 or more variables without manipulating them (negative correlation vs positive correlation)
Correlation
Self-reporting and a series of questions
survey
If a research study doesn’t manipulate any variables, what is it called?
Non-experimental
Inaccurately reporting on surveys
self-report bias
A precise description of how a variable is measured or manipulated in a specific study
Operational Definition
Method of choosing participants where every member of the population is represented

Measurement that identifies a single score to represent a whole distribution of scores
central tendency
How varied the data is
variance
When the graph has two peaks, which means not a lot of people scored in the middle
Bimodal distribution
Numerical value ranging from 0.1 to 1.0 (closer to 1.0 = more correlation)
Correlation coefficient
Measure of strength or magnitude of a relationship or difference between variables in a study (more ____ ____=more of an effect)
effect size
Means that the outcome is not due to chance
Statistically significant
A p-score less than 0.05 means ____
