\[ \text{Median} = \begin{cases} \text{Middle value} & \text{if odd number of values} \\ \text{Average of two middle values} & \text{if even number of values} \end{cases} \]

1. What is Median Sales Price?

The median sales price represents the middle value in a sorted list of property sales prices. Unlike the average, it is not affected by extreme outliers, making it a more reliable measure of central tendency in real estate markets.

2. How Does the Calculator Work?

The calculator uses the standard median calculation:

\[ \text{Median} = \begin{cases} \text{Middle value} & \text{if odd number of values} \\ \text{Average of two middle values} & \text{if even number of values} \end{cases} \]

Process:

Sort all sales prices in ascending order
If odd number of prices: take the middle value
If even number of prices: average the two middle values

Example: For prices [250000, 300000, 275000] → Sorted: [250000, 275000, 300000] → Median = 275000

3. Importance of Median Calculation

Details: Median sales price is crucial for real estate market analysis as it provides a more accurate representation of typical property values than the mean, which can be skewed by very high or very low sales.

4. Using the Calculator

Tips: Enter sales prices as comma-separated values (e.g., 250000, 300000, 275000). The calculator will automatically sort the values and calculate the median.

5. Frequently Asked Questions (FAQ)

Q1: Why use median instead of average for sales prices?
A: Median is less affected by extreme outliers (very high or very low prices) and better represents the typical property value in a market.

Q2: When is median more appropriate than mean?
A: Median is preferred when data is skewed or contains outliers, which is common in real estate markets with luxury properties or distressed sales.

Q3: How many data points are needed for reliable median calculation?
A: While median can be calculated with any number of values, reliable market analysis typically requires at least 20-30 sales in a given period and area.

Q4: Can median be used for other real estate metrics?
A: Yes, median is commonly used for price per square foot, days on market, and other real estate metrics where outliers may distort averages.

Q5: What are the limitations of median sales price?
A: Median doesn't show the price range distribution and may mask market segmentation (e.g., different price tiers within the same area).
