Significant Difference
Definition
In statistics, when we say there is a significant difference between two groups or variables, it means that the observed difference is unlikely due to chance alone. It suggests that there is likely a real effect or relationship between the variables being compared.
Analogy
Consider a significant difference like finding a diamond in a pile of rocks. It stands out and is not just a random occurrence. Similarly, when there is a significant difference in research findings, it indicates something noteworthy and meaningful.
