1
Q
explain whether there is likely to be a casual relationship between husmidity and visibility ?
A
High humidity (> 95%) can give rise to misty and foggy conditions, which in turn will cause lower visibility. Hence there is likely to be a causal relationship
2
Q
state two ways in which the large dataset could be better used to produce a model to descrieb the relationship between humidity and visibility ( the original data provided; provides data for 2 weeks)
A
The data provided is only useful for analysing the first two weeks of September. Random values throughout September should be used and analysis made of the whole month. The sample size could also be increased across multiple months as data between May and October is available
