1) State your interpretation of the meaning of the slope for the first graph you prepared of Volume of Steel Nuts (mL) versus Number of Steel Nuts. Hint: Understanding the meaning of a slope involves several factors: the units which are a ratio of the y axis units over the x axis units, the interpretation of the slope as “number of the y axis units for every one of the x axis units” and the concept that constructing the best line or curve that follows the trend in the data is a sort of averaging of the random error throughout the data.
