Introduction Non-parametric tests provide robust alternatives to parametric methods when data violate assumptions such as normality or homogeneity of variances. These tests are invaluable when dealing with ordinal data, small
Introduction Statistics is a powerful tool for analyzing, interpreting, and making inferences about data. Two fundamental branches of statistical analysis are parametric and non-parametric statistics. Understanding the differences, assumptions, and
Introduction Chi-square (χ²) tests are among the most widely used non-parametric statistical methods for analyzing categorical data. They provide a versatile set of tools for testing hypotheses about frequencies in
Introduction Analysis of Variance (ANOVA) and its variants are foundational techniques in inferential statistics used to compare means across groups and evaluate complex relationships between variables. Read More- Factor Analysis
Introduction Understanding the significance of differences in statistical measures such as means, variances, and correlation coefficients is essential in psychology and other behavioral sciences. These differences help researchers determine whether
Introduction to Statistical Inference Statistical inference allows scientists to make generalizations about populations using data drawn from samples. It is based on probability theory, specifically the behavior of sampling distributions.
Introduction Simple linear regression is a foundational statistical method used to model the relationship between two continuous variables: one independent (predictor) and one dependent (outcome). It helps predict the outcome
Introduction In behavioral sciences, understanding relationships between variables is critical. While simple correlation helps establish a linear relationship between two variables, real-world phenomena often involve more complex interdependencies. For example,
Introduction In psychological and educational research, not all variables are continuous. Many important variables — such as gender, pass/fail outcomes, yes/no responses, or item correctness — are dichotomous (i.e., having
Introduction Correlation is a foundational statistical concept used to examine the degree and direction of association between variables. It allows psychologists, educators, and social scientists to answer critical questions about
