          While Chi Squared Analysis offers many benefits, it's essential to consider the potential risks. One of the primary concerns is the misuse of the technique, leading to incorrect conclusions. To mitigate this risk, it's crucial to:

        1. Determine Significance: Determine the significance of the Chi Squared statistic, indicating whether the observed relationships are due to chance or not.

          2. Reality: Chi Squared Analysis can handle large datasets, but it's essential to ensure that the sample size is sufficient to ensure reliable results.

          The significance level, typically set at 0.05, determines the threshold for rejecting the null hypothesis. A lower significance level indicates a stricter test, while a higher level allows for more variation.

          Myth: Chi Squared Analysis is only suitable for small datasets.
