Question

sort the following phrases based on whether they apply to the experimental group or the control group in an experiment. sort each item to the appropriate bin. used to measure the bacterial diversity of unwashed hands used to measure the effect of hand soap on bacterial diversity the group that receives the treatment, while all other variables are kept constant used to establish a baseline for comparison used to measure the effect of hand sanitizer on bacterial diversity the group that does not receive the treatment, while all other variables are kept constant experimental group control group

Explanation:

In an experiment, the experimental group receives the treatment (like hand - soap or hand - sanitizer) to observe its effect on bacterial diversity. The control group is used to establish a baseline for comparison and measures the bacterial diversity of unwashed hands without any treatment.

Answer:

Experimental group:

• Used to measure the effect of hand soap on bacterial diversity
• The group that receives the treatment, while all other variables are kept constant
• Used to measure the effect of hand sanitizer on bacterial diversity

Control group:

• Used to measure the bacterial diversity of unwashed hands
• Used to establish a baseline for comparison
• The group that does not receive the treatment, while all other variables are kept constant
