A worksheet for taking note of:
The electrical resistance range of an analog sensor (Ohm).
Picking a mean resistance in that range.
Using a resistor of that resistance to build a Voltage Divider that will translate resistance into voltage.
Taking note of the min and max voltage range this gives you.
Connecting this variable voltage to the analog input of an arduino and using analogRead(); function to translate it into a 10bit range [0-1023].
Taking not of the min and max values within that 10bit range.
The process is also explained a bit more in this workshop-booklet:
