Biology
1 answer:
goblinko [34]3 years ago
8 0
If you do not control the variable in an experiment, you cannot have a reliable result. For instance if you are performing an experiment on how a certain plant grows with soda vs water, you cant put one plant in the fridge and one outside in the sun, as you do not know whether or not the different temperatures are affected your results. The variables are not controlled so you cannot know if the results are accurate.
