# Charts FAQs

Q: How do I read the charts? Is the content explained?

A: Charts and graphs, which are shown on the Property Details and Neighborhood Details pages, as well as in Reports, each have their own explanation. Next to every chart is a hyperlink, “About this Data,” that explains the content of the chart and how to interpret the data. Each chart also has an entry in this Knowledge Base that explains the chart and contains information about the sources of data and how frequently the data are updated. You can search using the title of the chart.

Q: Can I copy a chart into an email for a client?

A: To copy a chart into an email or other document for a client, use any screen capture software to make a copy of the image as it appears in RPR.

Q: What is a Median?

A: A median appears in many of the RPR charts and calculations. Consider the Median Estimated Home Value chart in the Neighborhood Details page, which represents property estimates for an area.

The median value is the middle value in a list of numbers. If the houses in the area are valued at \$58,000, \$125,000, \$136,000, \$143,000 and \$157,000, the median home value is \$136,000. So the Estimated Home Value chart would show that for a particular month, the median home value was \$136,000.

By contrast, the average (or mean) is calculated by adding all the numbers in a list and then dividing by the number of values in the list. In real estate, an average can be skewed by a very high or low value in the list, so it’s a less reliable number to use than the median. In the example above, for instance, the average home value would be \$123,800, which is significantly lower than the median.

Q: What geography levels are shown in the charts?

A: Because the data isn’t always available at smaller levels of geography that would be ideal for a detailed chart, some charts on Property Details pages and in reports are shown at a higher-level view. For instance, if ZIP code data isn’t available, a chart might instead show a metro area. The view may vary between charts.
