The mount command will tell you.  Look at this example:

# mount |grep boot
/dev/sda1 on /boot type ext3 (rw)
# umount /boot
# mount -o data=writeback /boot
# mount |grep boot
/dev/sda1 on /boot type ext3 (rw,data=writeback)

The first command didn't show the mode, so the default data=ordered applies.

Kind regards,

Herta
