Fill out the data sheet using the data provided. Calculate the uncertainties.

( I think the IV variable is an analogue scale and the DV instrument is a meter stick.) I am not sure though. Also could you please include the work you did for calculating uncertainty, I am very confused and need help on this topic)

The following data was collected with a meter-stick and analog-scale while the spring was held vertically. No masses were attached to the spring, the spring was just pulled down to each length specified and the analog's scale's "mass" was then read. The mass can be converted to a force using the gravitational acceleration constant, 9.8 m/s once grams are converted to kg. The spring constant, k, and it's uncertainty as provided by the spring manufacturer is also listed.
