The last six slides contain the data for six groups (therefore, six trials).
What you need to do is:1. Correct for the pressure/temperature fluctuations and thereby 2. Determine the rate of O2 disappearance (cell respiration) for both the dry peas and the
germinating peas at both 10C and 22C for each group.
You then need to:3. Combine the data of all six trials into four charts (germinating/non-germinating at two temps each). Ex:
Trial 0 to 5 min corrected diff(ml)
5 to 10 min corrected diff(ml)
Etc…

6Guess what you need to do next…
Respiration Readings of Non-Germinating Peas at 10°C
DO ALL WORK ELECTRONICALLY USING EXCEL
4. Calculate a mean, SD and SE for each time interval. Where there is a mean, there is an SD/SE:
Trial 0 to 5 min corrected diff(ml)
5 to 10 min corrected diff(ml)
Etc…

Now what to do with all of this data….hmmmm…
Respiration Readings of Non-Germinating Peas at 10°C
5. Make it easier to read…graphical display (graph it). What kind of graph? This one calls for an X-Y scatter plot…time goes on the x-axis, of course, and change in volume on the y.

DO NOT FORGET TO PUT STANDARD ERROR BARS ON EACH TIME POINT!!!
6. Answer all the questions in the old AP lab as well as the new one within the excel file. Edmodo the file to DrT by the deadline (see calendar).
