Different methods of data classification can influence how the reader understands and interprets the data.

If I was a journalist I would use the Natural Breaks classification. This is because it highlights more red zones, and I would be focusing on how the housing market of Vancouver is not affordable. If I were a real estate agent preparing a presentation for prospect home buyers near UBC I would use the Equal Interval classification. This is because it makes it appear as though the area around UBC has many areas in the low and medium range of housing costs. This however, makes me feels unethical, as these classifications can skew the maps to make provide a purpose, which creates much bias. I do not think it would be ethical to use 2011 data for housing costs in Vancouver because they have increased quite intensely in the last couple of years, so this would be inaccurate data.
