Absrobance spectrophotometry 400nm
1) When doing linear regression analysis on the any data, why does it make sense to "force" the fit through the origin?
2) Exacly what would be a physical explanation for non-zero intercept?
Homework Answers
1.while doing linear regression analysis on any data, we fit the line so that the line pass through the origin. We do this by considering the fact that the random errors in the measurement of the standards are small and negligible.
2. The physical significance of a non-zero intercept is there is no interferance, noise, contamination and interactions etc. so that the deviations are very less(<5%) making the graph linear.

A recent analysis of data for the 50 U.S. States on crime found the regression equation y=209.9+27.2xy=209.9+27.2x, where xx is the poverty rate and yy is the violent crime rate (measured as number of violent crimes per 100,000 people in the state). Interpret the slope of this line. Interpret the y-intercept of this line. Does this make sense in context of the problem? The state poverty rates ranged from 8.3 (Hawaii) to 27.2 (Mississippi). Over this range, find the range...

There is no integer The integer does not vary and is not random. It results from random process. Another reason.
