Normalize Ratios
- Add rows
- Type Equations
- =AVERAGE( : )
- =STDEV( : )
- Insert columns and input equation
- (cell 4-average)/Stdev)
- Scaling and centering
- =(B4-$B$2)/$B$3
Perform Statistical Analysis on the ratios
- Average log fold change for replicates
- =AVERAGE(B2:E2)
- Make columns "Avg_LogFC_all"
- New column "Tstat"- T statistic
=AVERAGE (N2:P2)/ STDEV (N2:P2)/SQRT (#of replicates)
- New column "Pvalue."
TDIST(ABSCR2), (degrees of freedom, 2)
- degree of freedom= #of replicates-1
