Experimental Design and Getting Ready
The strain comparison I used is dSWI_4, the dat individual dataset that you will analyze, the filename, the number of replicates for each strain and each time point in your data.
Classwork
The first steps I took to complete this assignment were performed in class as I followed along to Dr. Dahlquist's instructions. Note that each time the list below advances 1 number, I performed a save.
- After initially downloading the Excel document, I went through and deleted all of the columns that did not relate to me and my partner's strain (dsWI4). Then, I went through the data and replaced cells with "NA" with a blank string. There were 3641 replacements.
- I then created a new worksheet, naming it
Our total n would be 16 because we are analyzing 4 time points and we have 4 replicates.
After letting 16 = n, we applied the two following functions in order to receive our dSWI4_Fstat and dsWI4_p-values: =((n-5)/5)*(Y2-AD2) and =FDIST(AE2,5,n-5).
Next, I filtered through my p-value data to show only p-values less than 0.05. The result was 5475 records found.
Bonferonni and p value Correction
I started this section by creating two new colums with the label "dsWI4_Bonferonni_p-value". Next, I filled the entire first column of that using the following equation: (dSWI4_p-value * 6189) and filled the column AG.
