independence test
An independence test is a statistical method used to determine whether two variables are related or influence each other. For example, if we wanted to know if there is a connection between people's education level and their income, an independence test would help us see if changes in education levels lead to changes in income. If the test shows that the variables are independent, it means there's no significant relationship between them. This is useful in research to understand patterns and make informed decisions based on data.

An Independence Test is a statistical method used to determine whether two variables are related or whether they operate independently of each other. For example, it can assess if there is a connection between people’s education levels and their income. If the test shows independence, it means changes in one variable do not affect the other. If they are dependent, there may be a significant relationship. This test helps researchers and analysts understand patterns within data, guiding decisions in areas such as marketing, social sciences, and public policy.
