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.
