Definitions
The experiment proctor does not know the hypothesis or the control/non control groups.
Double-Blind Control
Experiments that take place in a non-controlled real-word enviroment
Field Experiments
When you have one sample of participants receive each condition of an experiment
Repeated measure design
When the participant answers to make themself look better to the researcher
social desirability
People who go second may experience boredom or fatigue
Order affects
Undesirable variables that affect the relationship between independent and dependent variables
Extraneous Variables
A standardized quantitative experiment based inside a controlled space
Lab experiments
Each sample is allocated to a different condition
Independent measure variable
participants activating differently than they typically would because they are aware they're being watched
reactivity
When the researcher sees what they are looking for to support their hypothesis
researcher bias
Used to predict a relationship between the independent and dependent variable
Experimental Hypothesis
researchers observe and record participants' behaviors in a natural setting, without actively manipulating any variables
Observational experiment
When participants are evaluated and grouped based on a certain characteristic
Match pair designs
When one variable increases the other decreases or vice verse
negative correlation
occurrences that take place based on a participants knowledge/awareness of being in a study
demand characteristics
Limitation of a study when certain characteristics of a sample affect the DV
Participant Variability
Experiments based on cause and affect
natural experiments
used to try and determine the characteristics of a population or particular phenomenon
Descriptive
When one variable increases the other increases as well or vice versa
Positive Correlation
undesirable variables that impact the relationship between the iv and dv
extraneous variables
When the participant answers to make themself look better to the researcher
Social Desirability
Groups of an experiment are made based off of a certain trait or behavior
Quasi Experiments
a systematic review of a focused topic in the literature that provides a quantitative estimate for the effect of a treatment intervention or exposure
Meta-analysis
When one variable changes another changes as well
principle correlation
limitation of a study when certain characteristics of a sample affect the DV.
