Rainfall and Normal Distribution
Rainfall is not symmetrical and so cannot be represented as a normal distribution
Process of Cleaning
- replace ‘tr’ with 0.025mm
- remove entries with ‘n/a’
Summers in:
- Jacksonville
- Beijing
- Perth
- Jacksonville: hot summer
- Beijing: hotter, wetter summers (colder winters)
- Perth = colder summers as seasons flipped
