What is the difference between quarterly medians and year to medians?
Various media present a variety of median prices. REIWA publications present both: • Quarterly medians which represent the median sales value for a particular quarter. Publication of this figure is generally restricted to overall markets such as Perth, Mandurah, Greater Bunbury and other regional centres, local government areas or sub-regional areas within the Perth market such as the Western Suburbs or Rockingham-Kwinana. • Year to or annual medians represent the median of all sales transactions that occurred over a 12 month period. Suburb data is often presented at this level, particularly in the Property Report as there are often insufficient sales or compositional variations of the property traded within each quarter that make quarterly reporting and the associated percentage changes potentially volatile. The accompanying example should assist in understanding these concepts.
