Probability and Statistical Data Analysis on The Severity of Road Accident

It was created by UK government world and it was collected for explaining the severity of road accidents.This case study shows the statistical data analysis on road traffic accidents.Road accident is the most unexpected thing to happen to a street user, however they still happen. The most disappointing thing is that we don't learn from our street mistakes.Consistently the lives of roughly 1.35 million individuals are stopped because of a street car accident. Somewhere in the range of 20 and 50 million additional individuals endure non- lethal wounds, with many bringing about an inability because of their physical issue.

We are given the task of calculating the testing of hypothesis,correlation and regression, and independence test Chi square.In this project ,we use R programming to analyze our data. My study aims are to know information on accidents across the world.Due to the format of the report a number of figures in the columns are- easting,  northing,accident data ,road surface,lighting conditions,weather conditions etc.It was created by UK government world and it was collected for explaining the severity of road accidents.For this project I have to chose a data set to complete my case study.From this project I learn many new things.I have done hypothesis test while doing that.I have made a box plot.Also I made a R calculation for test.I got evidence to conclude the mean manufacture date and ratio of road accidents.I have done R calculation for correlation and made scatter plot.

Based on all the findings through analytical study, a few conclusion can made.This information on accidents across Leeds.Data includes location,number of people and vehicles involved,road surface,weather conditions and severity of any casualties.

This project helped us to acquire a knowledge of statistical inference based on the database on road and traffic accidents.We observed the proportion of road accidents and road problems.The proportion of road accidents  increasing  day by day varies across the countries and continents respectively.We found out the number of accident happened every year.This implies that number of accidents and injuries increasing every year.In this case ,we observed male rate is higher than female.The global death percentages are gradually increased.
