The Variation of Traffic at Different Times in a Day - Essay Example

Statistics Memo A truck was determined to be a large vehicle that carries loads of goods. This vehicle has four or more wheels and it has a self propelled unit that contains the space used to store goods. The research also determined a car to be a medium sized vehicle that carries few passengers and it usually has four wheels. These definitions indicate that cars are smaller in size than trucks. I chose to collect the data on Thursday in the morning for consistency and simplicity. I also chose this day because it is a business working day of the week meaning that the data collected would display the real information of traffic on the street.

I also chose to count trucks and cars in the afternoon on the same day because this would help in maintaining consistency in the data. This would also help in comparing the morning flow of traffic with that of afternoon on the same days. I chose to collect data between 11.10 and 11.15 in the morning and between 14.50 and 14.55 in the afternoon. I chose these times randomly to ensure that my data was unbiased within one day. I did this by writing the morning and evening times on papers; I then mixed the pieces and picked them indiscriminately.

The benefit of analyzing data from different times separately is that it enables the marketing firm to determine the best period to conduct marketing campaigns in a day. However, this approach has a limitation of consuming more time than when the data is analyzed by combining the different time periods. This means that combining data saves time, but it fails in that it does not inform the marketer about the variation of traffic at different times in a day.
