2. Error Analysis: How accurate is your straight line? a. Examine your graph. Do most of your points fall on the best fit line, or are there outliers? b. The R² value is a measure of how close your experimental values match the corresponding values from the straight line. If R²>0.95, this indicates the straight line is a good approximation of your data. If R² <0.95, then then the line is not a good approximation of your data. Discuss how good your fit is based on the R² value.

Step 1: Analysis of straight line plot
The given case represents the analysis of the relationship between concentration and absorbance of a substance graphically. A plot of concentration and absorbance must be a straight line.
A straight line that best fits with the experimentally collected data is drawn. The R2 value indicates the accuracy of the graph with the collected values.
