Research Procedures
A quick way to gather data from large numbers of people
Survey
This type of research involves no interaction between the researcher and the subject; simply watch and learn!
Naturalistic Observation
Researchers must seek approval from this body when doing studies with humans
IRB (Institutional Review Board)
In order to find this value, simply add up all the numbers and divide
Mean
This variable is the one researchers measure in an experiment - the "effect" of cause and effect.
Dependent
When everyone in a population has an equal chance of being selected, you have this
Random Sample
Get in-depth analysis on one person or small group in this research method
Case Study
Make sure you tell your participants what they'll be doing and give them the choice to opt out if they want
Informed Consent
In a normal distribution, this is the percent of data that falls within 1 Standard Deviation of the mean
68%
This variable is manipulated by researchers - like different amounts of caffeine consumed
Independent
In an experiment, when participants do not know what group they are in, it's considered this type of study
Single-Blind
Simply compile data from a bunch of studies to carry out this type of research
Meta-Analysis
Keep your participants safe - physically AND mentally
Protection from Harm
When the mode is smaller than than the mean, this distribution is this type of skewed
Positive/Right
This is the range for the correlation coefficient (r)
-1 to +1
Try to avoid this type of sampling - just because it's easier doesn't mean it's good!
Convenience Sampling
This is the only type of research that allows for researchers to study cause-and-effect.
Experiment
Be sure to go over results, the true purpose of the study, and allow participants to ask questions
Debrief
If something is statistically significant, it is likely not due to chance and has a p-value less than this number
.05
This group serves as the baseline or comparison when conducting experiments
Control Group
When putting experiment participants into groups, use this technique to ensure equal chance
Random Assignment
Try to find relationship between variables in this type of research, but be wary of the illusory ones!
Correlation
When using this in a study, debriefing 100% required
Deception
Sometimes called practical significance, this tells us how impactful research is on people
Effect Size
When two variables increase or decrease together, they have this type of correlation
Positive
