The following 6 graphs (A-F) are standard curves for a carbohydrate assay by different methods. Each have the same axes and standards used for the standard curve.
Rank the graphs in the order that you would prefer to use the method - from best to least acceptable
JUSTIFY your answer. HINT - think of the characteristics of a good standard curve and apply this knowledge to compare these curves and rank them. Then explain what are the good and bad points about these graphs?
Word limit 150 words (this Question) Hint: use a set of criteria and label them whatever you wish leg it is red = 1, it is blue = 2 etc), then use these as your justifications - because some of the graphs have similar things right and wrong.

I'll primarily describe the qualities of a very good regular curve for Absorbance Vs. Conc (mg/L):
1. Absorbance must be 0 at 0 concentartion of analyte.
2. The Conc. of the ready solution must be so that it should cover the majority of the values because of the absorbance.
3. The curve must passes through the majority of the information points or maybe the data points must be good vicinity of this curve.
4. Standards must stand for the analytical range equally.
Further, I am going to rank the graphs by considering all of the above mentioned characterisitics.
Rank one: Curve F, as all the information points are equally distributed and also have zero intercept also. Thus, it is going to give value that is high for correlation coefficient.
Rank two: Curve C, this particular curve considers all of the above mentioned factors but as when compared to curve F, the previous information point isn't in close proximity.
Rank three: Curve A, it doesn't have all of the information points equally distributed.
Rank four: Curve D, it doesn't have all of the information points equally distributed. The way it's zero intercept that is the reason it's rank above curve B as well as E.
Rank five: Curve B, since it's much less value of intercept as when compared to Curve E.
Rank six: Curve E, it's extremely premium price of intercept, and that is not appropriate for an excellent regular curve.
