Discuss the variance between measurements (Standard Deviation) How well does the trend-line represent the points on the graph? (R2) What are some things that are done during the experiment that can be changed?

Spectrophotometric Determination of enzyme activity (Tyrosine)

Lab Report Common Issues: Discussion
Example
•For the standard curve
•What is in your graph, what does the data look like?
•What does the data tell you?
•Does it look like you expect it to, why/ why not?
•What do the error bars, R2, slope and trendline tell you?

Discussion
•Restate Hypothesis, and determine if it was correct or incorrect,
according to your data.
•Explain the science behind the experiment.
•What does each piece of data mean?
– Standard Curve?
– Potato types? How are they different?
– Explain the error in your Standard Deviation and R2 value
– What kind of errors may have occurred?

Error Analysis
•Discuss the variance between measurements (Standard Deviation)
•How well does the trend–line represent the points on the graph? (R2)
•What are some things that are done during the experiment that can
be changed?
