Hookes law experiment  -For my homework I am trying to calculate the spring constant of my rubber band and i got around 150nm? Does anyone know if I am doing it wrong. Asap thank you so much. I have attached a graph that I drew from my raw data. I am not sure How to find the spring constant. 150nm sounds a bit large, google said a rubber bands spring constant should be around 20nm.

Task
Report the following aspects of your experiment:
●
How did you obtain your experimental data? It may be useful to include a diagram
Raw data
●
●
Graph of your data
Did you obtain a straight-line graph?
●
Did you decide to repeat / redo some of your measurements?
Does the rubber band follow Hooke's law?
●
Is there evidence that the rubber band follows Hooke's law for in one region or interval of applie
weight, but does not follow it in another region or interval?
●
Can you find the "spring constant" of the rubber band.
