Introduction I am doing an investigation based on the prices of used cars. I have been given a database of 100 cars. I plan to use many different statistics methods such as pie charts, bar charts, scatter graphs, cumulative frequency curves and box and whisker plot because it is much more easier to understand the information if different types of statistics methods are used. I will describe and explain the many graphs I
