Psychological statistics is application of formulas, theorems, numbers and laws to psychology. Statistical methods for psychology include development and application statistical theory and methods for modeling psychological data. These methods include psychometrics, factor analysis, experimental designs, and Bayesian statistics. The article ...
SOCR – online tools for teaching statistics and probability theory; Speakeasy (computational environment) – numerical computational environment and programming language with many statistical and econometric analysis features; SPSS Modeler – comprehensive data mining and text analytics workbench; SPSS Statistics – comprehensive ...
Currently, CBTI programs fall into one of two categories: actuarial assessment programs or automated assessment programs. Actuarial assessment programs are based on statistical or actuarial prediction (e.g., statistical analyses, linear regression equations and Bayesian rules), which is empirically based while automated assessment programs consist of a series of if-then statements derived by ...
Psych is an R package providing routines for personality, psychometrics, and experimental psychology. Its functions support: Scale construction using factor analysis, cluster analysis, and reliability analysis; Basic descriptive statistics; Item response theory via factor analysis of tetrachoric and polychoric correlations
Exploratory data analysis, robust statistics, nonparametric statistics, and the development of statistical programming languages facilitated statisticians' work on scientific and engineering problems. Such problems included the fabrication of semiconductors and the understanding of communications networks, which concerned Bell Labs.
Qualitative psychological research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on.
SCiP is an organization of researchers interested in applications of computational techniques and methods in psychology. One focus over the past several years has been on aiding psychologists in using computers in their teaching and research, statistical analysis tools, web-based research, clinical applications, and computational modelling.
Previously, one of the most commonly used scale to evaluate emotional response was the Semantic Differential. However, according to Lang, this method is costly in both time and effort used by researchers and participants to complete the experiment, and requires statistical expertise, such as factor analysis, for resolution, which may not be accessible for all researchers.
