Study Notes
Research Practices and Statistics
-
Binomial Effect Size Display (BESD): A method used to present the size of an effect in a way that is easy to understand, such as the number of people who would need to receive a treatment for one person to benefit.
-
Questionable Research Practice: Deleting unusual responses and neglecting to report failed results is a questionable research practice that can lead to biased results.
Personality Inventories
- California Psychological Inventory (CPI): A personality inventory that focuses on normal, everyday personality traits and behaviors, distinguishing it from the MMPI.
- Minnesota Multiphase Personality Inventory (MMPI): A personality inventory used to assess personality traits and psychopathology, especially in a clinical or psychiatric setting.
Research Principles and Statistics
-
Open Research Principle: Aims to improve the transparency of scientific research by making methods, data, and results openly available.
-
Replication: A research principle that aims to verify the results of previous studies by repeating the experiment to increase confidence in the findings.
-
Rating Scales: A type of test that consists of a list of questions to be answered as True or False, Yes or No, or along a numeric scale, used to measure attitudes, opinions, or personality traits.
-
Cluster Analysis: A statistical technique used for finding clusters of related traits, tests, or items.
-
p-level: In statistical data analysis, the p-level represents the probability of obtaining the observed results by chance, with a lower p-level indicating statistical significance.
-
Type I Error: A type of error that occurs when a researcher rejects a true null hypothesis, concluding that there is an effect when there is none.
-
Type II Error: The mistake of thinking that one variable has no effect on another when it actually does.
-
Effect Size: A statistical measure that represents the magnitude or size of the difference between groups or the effect of an intervention, used to determine the practical significance of the results.
