Hypothesis: There will be a significant difference between the tadpole weight gain before applying the commercial fish-based diet and the measures after some diet to the diet.
Null hypothesis: There is no significant difference in the means of the tadpole weight before and after the commercial fish-based diet.
Alternative hypothesis: There is a significant difference in the means of the tadpole weight before and after the commercial fish-based diet.
The independent variable is the amount of the commercial fish-based diet given to tadpoles, since it is the variable that is controlled in the experiment. The dependent variable is the tadpole weight gain, since it is the variable that is investigated and measured.
The gain or not in tadpole weight is the variable that we would use to know if the change in diet affects the size of the tadpole.
