The 10-bit representation of it, yes. When you run analogRead(pin#), it uses the ATMEGA's ADC to measure the voltage of that pin as a 10-bit (0-1023) value.

Here's the resistor layout I used:

You'll want to set the if{} values half way between the nominal analogRead values. In the case of the schematic you attached: 70, 240, 415, 620 and 880 would be good middle-values.
