Null hypothesis: There is no statistically significant difference between the effect light
intensity has on the thickness of leaves on a chosen plant
Alternative hypothesis: There is a significant difference between the effect light intensity
has on the thickness of leaves on a chosen plant
Scientific introduction:
Variables:
Variables
Independent variables - The independent variable is the
variable you change, the variable
changed is the leaf sampled, it will
be decided what leaf to sample
using the random generator.
Dependant variables - The dependant variable is the
variable that is measured and the
dependant variable is the thickness
of the leaf as it will change
depending on the different light
intensities
Control variables
