Abstract
The major problematic of our assignment is trying to find if a relation between the weather and the number of traffic collision exists. In order to answer to this question, we had access to data from "MétéoSuisse" and "Police neuchâteloise". The weather data contains multiple variables such as temperature, humidity, precipitation and snowfall, while the traffic collision data contains the date and the number of accident recorded by the Police. This assignment contains different parts describing which statistic tools, databases, analysis and graphics we used.
There is a “Data” section, describing more specifically which variables we used and for what purpose. In that same section, there is a paragraph in which we explain the reason why we had to create a function and how we used it. There will also be a “Methodology” part explaining the way we analyzed a possible relation between weather condition and traffic collision.
The “Analyses” part of the project will show the results that came out of statistic tools such as, hypothesis test; correlation coefficient; graphics; data distribution. In the “Discussion” part, we will explain the way we interpreted the results, and verify if our intuition was right or wrong. The answer to our main question will be developed in this section. We included “R” codes that we used, in order to analyze our data, in section 8. Finally, we indicated sources we used in this project, such as our databases or some codes we used for the R software.
