Average Vs Median Explained

Average Vs Median Explained

Average: The average is calculated by adding up all the individual values and dividing this total by the number of observations.

Median: The median is calculated by taking the “middle” value, the value for which half of the observations are larger and half are smaller.

 

 

Why the median sale price is generally better to use than the average sale price.

Suppose that five homes sold in the same area and time frame with the following prices: $450,000, $460,000, $470,000-(median), $480,000, and $680,000. 

The median (middle) sale price is $4700,000, while the average price is (450,000 + 460,000 + 470,000 + 480,000 + 680,000) / 5 = $508,000. In this instance, the single high-priced home pulled up the average price well above the prices of the more typical homes in the market. Thus, the median price provides a better measure of the typical value of a home sold in the same area and time frame.

 

Don’t forget that adding and subtracting value for features and location are also important.  For example, if a house has a pool, it may add $25,000 or more to the value as compared to a like kind and quality home without a pool.
