Key Concepts

Correlation Analysis

Correlation analysis is a statistical method used to evaluate the degree to which two quantitative variables are related. In the context of survey research, it helps determine whether increases or decreases in one variable, such as income, are associated with increases or decreases in another variable, like life satisfaction or happiness.

Strength and Direction of Association

The concepts of strength and direction refer to how strongly two variables are related and whether the relationship is positive or negative. A positive association indicates that as one variable increases, the other tends to increase, while a negative association suggests an inverse relationship. The magnitude of the association, often measured by a correlation coefficient, informs researchers about the strength of the relationship.

Random Sampling

Random sampling is a foundational concept in survey research where each member of the target population has an equal chance of being selected. This technique helps ensure that the sample is representative of the population, reducing selection bias and allowing for more reliable inferences about the relationship between variables such as income and happiness.
