Lab 5, 8.1.7 to 8.1.9: Unusual Voltage Outputs

Hello everyone,
I just got my simulation for Lab 5 to work today, and after
calculating the percent error for the values I got in class, I
found that the voltages collected were nonsensical. I have been
in the lab for several hours trying to get a good result, but I
cannot make the output resemble my simulation. I am confused
because I am using the same circuit that I used that got good
data (percent errors around 40% at most) when RL was held
constant and RS was swept, which made me believe that the
voltage output for the other case should be correct, but it
seems to not be. It seems like my voltage output varies
constantly, and I cannot get a consistent output. I was
wondering if anyone else had this issue. My measured values
were 154mV for the 100 ohm value, 32.5mV for the 1k value, and
3.6mV for the 10k value. My simulation values were 0.919V,
0.566V, and 0.141V, so obviously very off. If anyone has any
pointers for what was incorrect, please let me know so I can
prevent any similar issue in the future.
