Correlation trap
Correlation does not imply causation.
Skewness trap
Rainfall and windspeed often skewed → median is better measure than mean.
Circular data trap
Cannot average wind direction numerically.
Seasonal comparison trap
Must mention season when comparing stations.
Rainfall zero-inflation
Many days with 0 rainfall distort averages.
Context requirement
Answers must reference weather, geography, or season, not pure numbers.
“Based on the LDS…” phrase
Required when justifying patterns or assumptions.
