The journalist and a real estate agent may choice two different classification methods to display because the former wants to objectively present the truth in a news yet the latter is thinking that how to increase their sales as much as possible. Since the roles have different approaches, if I’m a journalist, I will use Manual Breaks classification to present. First, the interval values are easy to understand, people generally have better understanding on housing prices that are in integers (e.g. $500,000, $1,000,000) rather than random numbers (e.g. $1,201,347). Secondly, the price ranges (intervals) are more appropriate to present the distribution of housing cost compare as to the Equal Interval classification because it shows what close to the reality of the Vancouver housing market. However, the real estate agent may choose the Equal Interval map to put on his/her flyers or website. The graph actual makes the properties in Vancouver seem more affordable than it should and we all know that’s not the truth. This is due to the intervals are much larger in this classification ($600,673 in each price ranges) and also result the average properties prices in UBC fall into the second-cheapest categories in the scope of the entire Vancouver market. Also, the data I using to present is from 2011, so it’s pretty much dated. Since then, housing affordability in Vancouver has sharply decrease because of the inflating properties price within the city. Therefore, the 2011 data cannot properly present the nowadays housing market in metro Vancouver.
