Conclusion Gasoline versus Hybrid Vehicles 1. Introduction This study involves a comparison between gasoline and hybrid vehicles in order to determine the one that is better than the other. Each of the vehicle types has a set of unique advantages and disadvantages. From the attributes identified in the comparison, hybrid vehicles are better than the ordinary gasoline vehicles in various aspects of performance. The performance of hybrid vehicles is characterized by more power and covers more miles per gallon of fuel than the gasoline vehicles. Additionally, the analysis of performance shows that hybrid vehicles are more favorable to the environment than the gasoline vehicles, even though hybrid also generates pollution. However, in the aspect of cost efficiency and effectiveness, it is cheaper to produce and operate a gasoline vehicle than a hybrid vehicle. 2. Background The target audience for this project is the young drivers who are in the decision making process on which vehicle to buy between the gasoline cars and hybrid vehicles. Of course, the decision on the purchase of a car is very stressful in the target market full of varieties (Ehrenberg 49). From the inherent view, it is easier to conclude that hybrid vehicles are of more ben3fits than gasoline cars. This research is meant to use practical data to provide an informed ground to support the decision by referring to the pros and cons of using hybrid and gasoline vehicles. The advantages of hybrid vehicles are seen to be higher gas mileage, minimal taxation and environmental safety. Looking at the advantages of gasoline cars, they generate more power and are less expensive to produce and operate. Comparing the disadvantages, it is very expensive to produce and operate hybrid vehicles. Secondly, they generate less power compared to gasoline vehicles. On the other hand, gasoline vehicles have less gas mileage and do not reduce the taxes. The images of gasoline car and hybrid car are shown below: Figure 1: Gasoline Car - Honda Accord Sedan Figure 2: Hybrid Car - Honda Civic Sedan 3. Aims and Objectives The objective of this study is to establish the relationship between the vehicle model and the performance in order to identify the vehicle of choice between gasoline and hybrid vehicle. It intends to use practical data collected in the market, to make informed decision on the vehicle to buy. This implies that the data will have to be analyzed quantitatively after comparing the advantages and disadvantages of the two models. The advantages and disadvantages are summarized in the tables 1 and 2 below: Car Model Honda Civic Hybrid Estimated Mileage 17,000 Gas Mileage Average 48 Cost factor cost / gallon $3.20 Annual gas cost $950.00 Initial Price $19,900 Annual Gas Cost $8,000 Tax Saving ($700) Total Cost $27,300 Table 1: Hybrid Car Table 2: Gasoline Car 4. Research Questions The study questions for this study include: Does the vehicle model determine the age determine the cost, environmental safety, the mileage covered and the power generated? Which vehicle model is better than the other in the target market? 5. Hypothesis From the study questions, the hypotheses of this study include: The type or model of a vehicle determines the performance of the vehicles in terms of cost, environment safety, gas mileage and the power generated. Hybrid vehicles are better in performance than gasoline vehicles. 6. Data Analysis and Results 6.1. Data The data originated from the http://www.statcan.gc.ca/start-debut-eng.html library. The data is a sample is a historical data for the research carried out to determine the transport issues affecting the choice of vehicles to purchase among drivers. The sample size is 223. From the various analysis methods used, the research will emphasize on the regression and correlation coefficients among other functions. 6.2. Relevance The data is good because it contains realistic, measurable data from a real target. The sample size is sufficient and enough to generate the required analysis. The limitation with the data is that it does not have time variable, so time series is not measurable. 6.3. The Data The data to be used is shown in table 3 in the appendix section. The research uses various variables to represent the economic status of the population as shown below: Variable Description Explanation VM Vehicle Model 1 = Hybrid, 0 = Gasoline M Mileage Measured in Miles FC Fuel cost per gallon In US $ AGM Average Gas Mileage In Miles V Tax saving In % (30 % bracket) SP Starting Price In US $ EE Environmental Effect 0 to 5 rating 0 = no effect, 1 = little effect, 2 = Moderate effect, 3 = strong effect, 4 = very strong effect, 5 = critical effect on the environment Table 3: Variable Definition 6.4.

The rest of the variables are either in negative or no correlation with the vehicle models. Fig 3: Plot of Linear Regression The plotteg graph of the regression shows the coefficient of linear regression as 0.8. It shows that the milleage is directly proportional to the vehicle model variable. In this regard, the higher the value, the greazter is the milleage. Hybrid vehicles are thus better than ordinary gasoline vehicles. 6.5.

This shows that hybrid vehicles are better than gasoline vehicles. 6.6.

Hidden and Extraneous Variables AGM and V are the hidden and extraneous variables since they have been omitted by the analysis. The hidden and extraneous variables are omitted because they are not statistically significant as there is null correlation between them and the dependent variable, which is the vehicle model (VM). 6.10. Graphs Box Plot Fig 7: Box Plot Fig 8: Scattered Dots The box plot and the scattered dot matrix indicate that influence of each variable on the performance. Mileage is the most influential, showing that since hybrid vehicle drivers covers larger milleages, the drivers are the determinant of the vehicle mileages in this research. Fig 9: Scattered Dots between FC and M There Fuel Consumption is equally spread in the distribution such that there is no vehicle model that clearly consumes more than the other model. Pie Chart Pie chart The pie chart shows 1 (hybrid vehicles) to be taking the greatest percentage of influence in the target market. There are more drivers for hybrid vehicles than for gasoline vehicles. 7. Conclusion From the analysis, the gasoline vehicles and hybrid vehicles are all good to own. The only difference is made by the nature of the drivers. There is no better vehicle than the other since both of them demonstrate equal advantages and disadvantages. Looking at the fuel consumption, the rate of fuel usage is not dependent on the vehicle model but on the way it is driven. Works Cited Ehrenberg, Smith.
