Using the range sliders to filter out higher priced homes does not solve all of
the analysis issues with respect to home price. Because the price range slider is
scaled to fit the full range of home prices, there is not enough display space to
fine tune the slider in the price range up to a million dollars. The needed detailed
granularity of the slider is not available. To provide more control when

Right-click on the CmpltHomes.csv dataset.
Select “Create filtered dataset”.
Drag the right (high) end of the “price” slider to the left so as to include only

For “schoolDistrict”, specify “Alpine” and “Provo”.
Enter a name of “CheapCondos”.
Click “Create”.
Although at this time, we will not conduct analyses using the newly created
CheapCondos dataset,
