Examples
I think the table formatting got clobbered by conversion to Word. raweb is exactly right that the table shows ADC readings for a voltage divider with different resistor values.
This is often either one or ten megohms ; the standardization of the input resistance allows the use of external high-resistance probes which form a voltage divider with the input resistance to extend voltage range up to tens of thousands of volts.
The primary benefit of a wheatstone bridge is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider ).
Unless you intend to power something off of the 3.3V step-down, sensing a voltage divider resistor ladder is fine.
