NULL FORM
CAUSE AND EFFECT
HYPOTHESIS

16.  Operational- stated in the

FORMS OF HYPOTHESIS

17.  Stated Problem: Comparing the effects of
fertilizer A and fertilizer B on the growth of
okra plants.
ALTERNATIVE: Fertilizer A is more effective in
terms of the average height per plant than fertilizer B.
NULL: Fertilizer A is not as effective as fertilizer B in
terms of the time of flowering per plant.
C and E: If the average height per plant using fertilizer
A is taller than using fertilizer B then fertilizer A is
more effective.
