Dependent sources and MOSFET Lab

In this lab we will examine the behavior of a MOSFET for different voltages across the MOSFET. 
This is the diagram we followed for the circuit set up. The resistor used measured 97.9 Ohm's in our DMM. 
Here is how we hooked up our circuit according to the diagram shown in the first picture. 
We increased our variable voltage source (connected across the MOSFET) by 0.1V
And measured current in the circuit accordingly. As noted by our table, the MOSFET has a threshold voltage of about 1.4V where there is no current that flows through the circuit. The current then increases greatly per 0.1V increment  until it levels out at about 2.9V then remains close to constant.
