Summary Table
The Summary Table displays descriptive statistics for each sample group.
Each group is displayed as a row in the table. If you select a Control group,
you will see the following statistics:
• P-Value —the P-value is the result of comparing the selected
group with the control.
• Fold Change — the fold change is the base 2 logarithm of the ratio
between the control group and group being compared. The minus
sign indicates the down regulation of the group compared to the
control. No sign indicates the up regulation of the group compared
to the control.
For example, if the mean of the control group is 1 and the mean of the
group being compared is 1, then the fold change is 0. If the mean of the
group being compared is 2, then the fold change is 1. The following
table shows the calculated fold change for different control groups and
compare groups.
