Extract of sample
The lab report "Comparison of Two Sets of Data" overviews two datasets of gross motor vehicle domestic weights from the year 2002 and from the year 2004. This report applied information from a secondary source for its investigation. The collected data was then subjected to statistical analysis using excel from which cumulative were developed. Further, histograms were developed to facilitate analysis of the two sets of data.
Gross vehicle domestic weight refers to the maximum weight of a vehicle based on the manufacturer’s specification. It normally indicates the combined weights of all elements of a vehicle such as a frame, body, engine, devices, luggage, and passengers. This information is contained in vehicles’ registration documents.
Statistical applications that offer ground for comparing and contrasting records of motor vehicle weights over periods can be used to investigate the existence of a change in a trend of gross weights. The combination of statistics from the two periods of time allows for easier analysis into identifying similarities and differences between the two sets of data. A review of the combined frequency distribution table, for example, identifies a comparative trend in the weights of the vehicles between the intervals less than 20 kipps up to 69.9 kipps. Though the paired frequencies within this range vary across the two years, the differences are significantly small, falling within a one percent disparity. A difference is observed beyond 70 kipps frequencies reported in the year 2004. ...
