Common Mistakes to Avoid
- Ignoring assumptions: Failing to verify statistical assumptions can lead to erroneous conclusions.
- Overfitting models: Creating overly complex models that fit the sample data too closely can result in poor generalization.
- Misinterpreting significance tests: P-values only indicate statistical significance, not practical importance.
- Ignoring outliers: Extreme data points can influence statistical results; handle them appropriately.
- Relying solely on statistical software: While software can automate calculations, a critical understanding of the underlying principles is essential.
