1: Introduction To Psychological Statistics Flashcards
The systematic study of collecting, organizing, analyzing, and interpreting psychological data to derive new insights and knowledge.
Psychological Statistics
A representative subset of a larger population used for research to draw meaningful conclusions and make inferences about the entire population.
Sample
Refers to the entire group under consideration. Defining it, is crucial and it is contextualized within the focus of the study.
Population
A notable challenge in psychology lies in accurately defining and establishing __________ for complex phenomena.
Parameters
___________ is a cornerstone of scientific method. Researchers reanalyze studies to ascertain whether consistent results are obtained across multiple instances.
Scientific Replication
_________ are characteristics that exhibit variation. The opposite of constant. Understanding variability and covariations (correlations) between _________ is essential.
Variables
Statistical test comparing means of two groups.
T-Test
Compares means of more than two groups.
ANOVA/Analysis of Variance
Quantitative measures computed from sample data, utilized for analysis.
Statistics
Numerical description characterizing a population’s attribute.
Parameters
Statistics that summarize and describe data.
Descriptive Statistics
___________ statistics make broader inferences about populations based on sample data.
___________ statistics involves generalizing findings from a sample to a larger population using techniques like estimation and hypothesis testing.
Inferential
________ is the disparity between sample statistics and true population parameters due to random sampling. Minimizing it entails using larger, representative samples.
Sampling Error
__________ are numerical values representing characteristics of an entire population.
Population Parameters
____________ combines and statistically analyzes results from multiple studies.
Meta-analysis
