step in analysing the data is determining if outliers exists within the data. The presence of outliers must be evaluated because their existence could distort the data and make it inaccurate. In order to determine if outliers exist the average and standard deviation must be calculated in order to calculate the Z score‚ which will show‚ wither or not outliers exist. In this instance to outliers where found present in the data set as all of the data fell within the +3‚-3 range‚ the largest positive outlier

sector is already responsible for 12% of the UK’s overall climate change impact (taking into account the higher impact of carbon emissions at altitude). If recent rates of growth continue‚ aviation emissions could account for more than 30% of the UK’s emissions by 2050. Our work involves ensuring that these emissions are included in the UK Climate Change Act‚ the EU Emissions Trading System (ETS) and other international frameworks.
