Read the descriptions of two experiments below.
Experiment 1:
A student tested to see if sunflower growth was affected
by the hardness of the soil. She used control and
experimental groups. She repeated her experiment several
times, and each time found that the hardness of the soil
did not affect the growth.
Experiment 2:
A student tested to see if the temperature of water
affected the growth of cacti. She used control and
experimental groups. Her data supported her hypothesis.
Which experiment most likely has greater reliability, and why?
OA. Number 1, because each experiment got the same results
OB. Number 2, because it has control groups
OC. Number 1, because the experiment disproved the hypothesis
OD. Number 2, because it proved the hypothesis

Both experiments used control and experimental groups. However, experiment 1 repeated the same experiment several times. Option A. Number 1, because each experiment got the same results.

What does replication mean in an experiment?

Following the scientific method, an experiment needs to be replicable.

Replication refers to the repeatition of a research study, under different situations, with different subjects and by different researchers to determine the safety of the original findings and the possibility of generalizing them to other situations and participants.

Replicability is the possibility of carrying out the same experiment by other researchers. When repeating the experiment, results should be the same or with a minimal variation. Results heterogeneity should be minimal.

From the exposed experiments, experiment number 1 is more reliable. Option A is correct. Number 1, because each experiment got the same results.

Both experiments used the control and experimental groups. However, experiment 1 repeated the same experiment several times, and every time the results were the same.
