CORRELATIONAL STATISTICS Meaning and
Definition
-
Correlational statistics refers to a branch of statistical analysis that examines relationships between variables without making any assumptions about causality. It aims to determine the extent and direction of association or correlation between two or more variables. The term "correlation" refers to a statistical measure of the strength and direction of a relationship between two variables.
In correlational statistics, variables are measured and analyzed to uncover patterns or relationships that may exist between them. These relationships can be positive, indicating that as one variable increases, the other also increases. Conversely, they can be negative, implying that as one variable increases, the other decreases. Correlational statistics also helps identify the absence of any significant relationship.
One commonly used measure in correlational statistics is the correlation coefficient, which quantifies the strength and direction of the relationship between variables. The correlation coefficient ranges between -1 and +1. A value of +1 indicates a perfect positive correlation where the variables move in the same direction, while a value of -1 signifies a perfect negative correlation where the variables move in opposite directions. A correlation coefficient close to 0 implies no correlation or a weak relationship between the variables.
Correlational statistics is widely used in various fields including psychology, sociology, economics, and biology, among others. It provides valuable insights into the relationships between variables and helps researchers make predictions, identify patterns, and explore the potential associations among different factors. Despite its usefulness, correlational statistics should not be mistaken for causal relationships; additional research designs or experiments may be required to establish cause-and-effect relationships.

Etymology of CORRELATIONAL STATISTICS
The word "correlational" comes from the noun "correlation", which originated from the Latin word "correlātus" (past participle of correlāre). "Correlāre" is a combination of "cor-" (meaning "together") and "relāre" (meaning "to carry or bring back"). This Latin root suggests the idea of bringing or carrying things together. In the context of statistics, correlation refers to the relationship between two or more variables.
The term "statistics" has roots in Ancient Greek. It derives from the word "statistikos", which means "of or pertaining to statistics". This Greek word comes from "statistēs", meaning "statesman" or "political leader". Originally, the term statistics was used to describe information and data relevant to state affairs or public affairs.
