  • Incorrectly interpreting the p-value, misunderstanding the relationship between the variables, or neglecting the test's limitations.

    • While the Chi Square test offers numerous benefits, there are also risks to be aware of:

  • Assumptions: The Chi Square test relies on critical assumptions about the data and the absence of hidden structures beyond the observed variables. Breaking these assumptions can render the test inaccurate.
    • Sample size limitations: The test requires a sufficiently large sample size to yield reliable results. Small sample sizes can lead to Type II errors, making it challenging to determine if any statistically significant relationship exists.

      Q: Can I use the Chi Square test for continuous data?

      At its core, the Chi Square test is a non-parametric test used to determine whether there is a significant association between two categorical variables. In essence, it helps you understand how often you can expect to observe the data you see under a specific set of assumptions. The test produces a p-value, which indicates the probability of observing the data you've collected assuming there is no actual relationship between the variables. If the p-value falls below a certain threshold, you can conclude that there is a statistically significant association.
