DO NOT LOOK at the question and then look at the data to answer the question.
Look closely at the graph or table
look very carefully at the axes - have they plotted mean or rate or time, mass/volume or concentration ?
can you see range bars ?
In a table what range is in the replicates when you compare to the mean ?
what trends can you observe ? then think about what principle of biology is being shown by the the trends.
How would you explain the highest value, the lowest value, the point at which the line crosses the x axis, how would you explain the largest range, how would you change the experiment to reduce the spread in the data ?
