31,477 PointsUsage of absolute references VS using relative reference of value
Why did we use absolute reference for selecting the housing units for the Median Rental tab, but then why did we use relative reference only for selecting data from the Population & units tab?

231,261 PointsSince the range is complete columns, the absolute references were not needed. He just demonstrated the technique for use when the range is limited.
About 2 minutes into the video he explains, "One thing I want to mention here, in the example, the range I selected included entire columns, meaning all the way down to the bottom of the spreadsheet. Now if we decide not to choose entire columns for the range, we need to make the range an absolute reference." Then he demonstrates the technique and continues, "The absolute reference will make sure the range is static. So when you drag the formula down, it won't change the placement of your range. I usually just play it safe and select the entire columns for the range."
