The progress of technology and advancement of AI provides opportunities to treat patients with solutions that are taliored to each inidividual based on each individual's life style and habbits, our system provides the most important change that will maximize the indiviual's health and well-being.

1. Developed questionnaire to collect data about participants’ habits and their health status
2. Handed out and collected the questionnaires
3. Classified each participant as “healthy” or “not healthy” using the following procedure:
   1. Found the median number of days that participants were sick in the past 3 months
   2. Individuals who were sick less than the median are considered “healthy” as the majority of the people can learn from them
   3. The rest of the individuals are considered “sick”.
4. Processed the data by using data science methodology
   1. For questions with yes/no answers, we used the number 1 to represent yes and 0 to represent no.
   2. For questions with multiple choices, we used 1 to represent answers above the average and 0 to represent numbers below average
      1. Example: our questionnaires show that people take an average of 5.4 showers per week. Therefore, for people who shower more frequently we converted their answer from the number of times they shower to ‘1’. And for people who shower less than 5.4 times per week we converted their number of times they shower to ‘0’.

At this point, all the answers have been converted to either 1 or 0. This allows to create a decision tree with two branches: 1 and 0.

5. Analyzed the data using a Decision Tree, and found the most common behaviours for healthy people
6. Drew conclusion

Based on Question 1 we found that among the 159 participants, 52 are considered “healthy”, which is defined in the Procedure slide.

We found the one single habit that is the most common among those healthy individuals. The table below shows how many healthy people said Yes and No to each question (Q2-Q19).

Step 1: Question 9 shows the most common habit among healthy people, which is washing hands after using the bathroom

Now we look at the 47 healthy people who wash hands after bathroom, and look for the single habit that is the most common among these people. The table below shows how many healthy people who wash hands said Yes and No to each question (Q2-Q19).

Step 2: 

We see that the one single habit that is the most common for healthy people who wash hands after using the bathroom is Q11: taking vitamins.

Now we look at the 35 healthy people who wash hands and take vitamins, and look for the single habit that is the most common among these people.

Step 3: 

We see that the one single habit that is the most common for healthy people who wash hands after using the bathroom and take vitamins is Q14: shower often enough.

Analysis Summary

From the data we collected, 52 people were healthy in the past 3 months, and 107 people were sick at least once. We found the common habits that healthy people have.

The most common habit among the healthy people is:

1. Washing hands after using the bathroom (Q9): out of 52 the healthy people, 47 wash hands, which is more common among the participants than any other behaviour
2. The most common habit among the most healthy people who also wash hands after bathroom is: Taking vitamins on regular basis (Q11): out of the 47 healthy people who wash hands, 35 take vitamins, which is more common than any other behaviour
3. The most common habit with the most healthy people who wash hands after bathroom and take vitamins is: Showering regularly (Q14): 26 of the 35 healthy people who wash hands and take vitamins also shower more often than the average participants.

In our project we demonstrate that even a simple decision tree that is based on information from only 159 people can be used to derive relevant information about healthy habits and personalize guidance towards healthier lifestyle.

We conclude that questionnaires with more questions that are given to more people, can create a more accurate system and tailor better personalized programs to each individual, maximizing the potential to improve the population’s health.

I used google sheets to make the data tables so I could find the healthiest habits.
