What is the independent and dependent variable, control and constant of this experiment?

Your friend tells you that there is a new pill called "Short-B-Gone". It is supposed to make people taller if they take it every day for 10 days, You decide to conduct an experiment on it. You have 5 people take "Short-B-Gone" and label them group A. you have 5 other people take a normal vitamin and label them group B. After 10 days,group A grows an average of 4 cm and group B shows no growth at all.|||independent: pill vs no pill. This is what the researcher changed on purpose to see how it will effect the results of the study





dependent: height. This is the outcome of the study which has to be measurable (measured by ruler in cm)





control group: Those who took the vitamins





constant: same number of pills taken, taken every 10 days, should have people of the same height.
