Common Pitfalls to Avoid

Over-relying on p-values without considering effect sizes
Ignoring model assumptions
Data dredging and p-hacking
Confusing correlation with causation
Not checking for outliers and influential points
Failing to visualize data before modeling
Overfitting models to training data
Misinterpreting confidence intervals
Not accounting for multiple comparisons

Use version control (Git) for all statistical code
Write clean, documented, modular code
Use R Markdown/Jupyter notebooks for literate programming
Set random seeds for reproducibility
Document software versions and dependencies
Share data and code when possible
Follow FAIR principles (Findable, Accessible, Interoperable, Reusable)
