The P-value (probability value) is a number between 0 and 1 that shows how likely the observed results are if the null hypothesis (H₀) is true.
The T-test is a statistical test used to compare means and check whether the difference observed between two datasets is statistically significant or due to random variation.
Data in Research is the foundation of every study. Without data, no analysis, interpretation, or conclusion can be made. Whether in biology, medicine, social sciences, or business research, data provides the evidence that supports or rejects a hypothesis.
The Z-test is a parametric statistical test used to determine whether there is a significant difference between a sample and a population, or between two independent samples.
ANOVA (Analysis of Variance) is a statistical method used to compare the means of three or more groups and determine whether there are significant differences among them.

Descriptive studies are types of research that focuses on describing the distribution of disease, health conditions, or other characteristics in a population.
Two of the most common mistakes in research are Type I error and Type II error. This article explains what Type I and Type II errors are, their causes, probabilities, differences, and real-life examples in simple, clear language.
