Which skin cream between anti-bacterial, non-scented, and exfoliating works best at getting rid of acne?

# data[].attributes.body
Cream 1: anti-bacterial
Cream 2: unscented
Cream 3: exfoliating

# data[].attributes.body
Our experiment units are 150 people pulled from a beauty salon randomized into 3 different groups.

# data[].attributes.body
Our experiment units were founded in Andy’s salon in California by dermatologists who find people who need help with getting rid of their acne.

# data[].attributes.body
Our explanatory variable is the type of cream Our experiment units get assigned to.

# data[].attributes.body
Our response variable is the cream that worked most successfully of getting rid of the acne with in the 3 month period.

# data[].attributes.body
We randomly numbered our people 1 to 50 and put 30 people in each group. A potential lurking variable is some people may have worse acne than others.

# data[].attributes.body
After the 3 months we are going to switch the groups 2 more times. 3 months each time so we can get full understanding of the most effective cream.

Our control group is the group with the exfoliating cream because we don’t have a placebo and that is the only cream with a rough texture.

# data[].attributes.body
At the end of the 3 month period of time average BMI cream 1 was 30, cream 2 was 30.6, cream 3 was 40.2.

We blind our subject because we are not filling them with the cream they are using but it is kind of an obvious distinction between the 3 creams. It is also double blind because no one clones each other.

# data[].attributes.body
With a sample size of 150 people evenly split into 3 groups of 50 of our margin of error which is 12.2%.

# data[].attributes.body
I don’t believe that this is statistically significant because there are so many other products that work better and everyone has different skin types.

Our results showed that cream 3 which was the exfoliating cream was the most effective cream out of the 3 trials. The exfoliating cream is now distributed in your local drug stores such as Walgreens all over the country.
