(I was not sure where to post this, hope it is not the wrong sub-forum)
I have a data-set and I am trying to make an equation out of it. Specifically, I have a distance-sensor and have measured readings at different distances. (Below is my data set.) The reading is about halved when the distance is doubled. What sort of equation does this correspond to? My stomach feeling says the answer is simple, but my creativity is a bit low at the time...
Thanks a lot for helping me out!
PS: I am aware that the sensor readings are a bit crappy. I made the sensor myself from two laser beams and a camera. The readings are camera image pixels between the laser beams.
