Variables
something that has more than one possible value

Confounding Variable

Random
having independent and equal chance of selection
Reliability
getting the same results consistently
Validity
accuracy
If something is not reliable, can it be valid?

Research Designs
how experiments are set up
- types: descriptive, correlational, quasi-experimental, experimental
Descriptive Research Design
describes some phenomenon
- types: case studies and qualitative studies
Case Study
type of descriptive research design where on unique bounded system is studied
- ex: an individual, a household
Qualitative Study
type of descriptive research design that studies description of qualities
Correlational Research Design
studying the relationship between two groups
- types: cross-sectional and longitudinal
Cross-Sectional Study
type of correlational study that compares people at different points in life
- ex: 10 yo, 20 yo, and 30 yo
Longitudinal Study
type of correlational study that follows the same group of people over a long period of time
Quasi-Experimental
research design where the researcher aims to find a causal relationship between two variables without randomization
Experimental
research design where the researcher has full control of manipulation
Research Methods
ways to collect data
- types: observations, surveys/questionnaires, exams/tests
Observations
a type of research method that provides behavior of participants
- disadvantages: misinterpretations, articial behaviors
- types: naturalistic and lab
Naturalistic Observation
researcher goes to the setting of the participant to collect data
Lab Observation
participants goes to the researcher for data collection
Surveys/Questionnaires
a type of research method that gets opinions of participants
- disadvantages: limited responses, untruthful
- types: self-administered, interview, focus groups
