Do hair skin and nail supplements really increase overall growth rate?

# data[].attributes.body
We did not make this a blind study because we did not incorporate placebo pills this time so those who weren’t taking vitamins were obviously not taking the Hair Skin and Nail supplements. There is no double blind either because our team was either giving participants vitamins or not.

# data[].attributes.body
40 subjects, 20 men and 20 women were randomly selected. 10 of those men and 10 of those women take 2 Hair, Skin, and Nail supplements once a day right before bed, while the other half does not take anything.

# data[].attributes.body
With a sample size of 40, our margin error was 15.8%. This low margin of error is good, representing the population well.

We matched up people purely based on gender so we could see clearly whether supplements work better on one gender than the other. This will help us clearly compare our results when done.

At the end of the 6 months, the patientshair will once again be measured. We’ll gather the data of those who took the vitamins and compare it to those who did not in order to see who had the greater growth rate.

Our control group will be those who are not taking the Hair Skin and Nail supplements. We decided not to do a placebo so we could see the progress with vs without supplemental vitamins.

We will repeat this study at a different salon and barber shop, choosing 40 people, once again being 20 men and 20 women. Next time we’ll add a placebo pill to see the efficiency of the vitamins.

Our experimental units were found in selected salons and barber shops. Those who were regulars were offered to partake in this free study. Their average growth rates were measured by these salons and barber shops in order to verify change in the future studies.

# data[].attributes.body
We took the first 20 men participants the barber shops and the first 20 women participants the salons gave us. We randomly split the men in half and then the women in half. 10 men and 10 women were given the Hair Skin and Nail supplements while the others did not. Potential lurking variables are genetics, race, overall physical health, and diet.

# data[].attributes.body
Our explanatory variable was whether or not the patient took Hair Skin and Nail supplements.

# data[].attributes.body
Our outcome was posted in the salons and on their websites, encouraging women to buy Hair Skin and Nail supplements. These vitamins are now sold at local salons.

# data[].attributes.body
At the end of the 6 month study, the biggest difference seen was in the women who were taking the Hair Skin and Nail vitamins. Their personal improvements came out with a higher average than any of the other study groups. The supplements in general did prove a faster growth rate, though the men’s growth rate wasn’t as significant.

# data[].attributes.body
We clustered our 40 participants and their difference was 6 inches. Therefore the results are significant, especially because 6 inches could not have been by chance.
