Examining the Therapeutic Touch
Welcome to Lab 6!
After such an extensive introduction to programming for data science, we are finally moving into the section of
the course where we can apply our new skils to answer real questions.
In this lab, we'll use testing techniques that were introduced in lecture to test the idea of the therapeutic touch,
the idea that some practictioners can feel and massage your human energy field.

, What is the Therapeutic Touch
The Therapeutic Touch (TT) is the idea that everyone can field the Human Energy Field (HEF) around individuals.
Certain practictioners claim they have the ability to feel the HEF and can massage it in order to promote health
and relaxation in individuals. Those who practice TT have described different people's HEFs as "warm as Jell-
O" and "tactile as taffy".
TT was a popular technique used throughout the 20th century that was toted to be a great way to bring balance
to a person's health.
Emily Rosa
Emily Rosa was a 4th grade student who had wide exposure to the world of TT due to her parents. Her parents
were both medical practitioners and skeptics of the idea of TT.
For her 4th grade science fair project, Emily decided to test whether or not TT practitioners could truly had any
interaction with a person's HEF.
Question 1: Discuss with the individuals around you how you would set up an experiment to test this.
SOLUTION: No real solution, just want to get students thinking about creating experiments to test any
hypothesis.
Emily's Experiment
Emily's experiement was clean, simple, elegant, and effective. Due to her parents occupations in the medical
field, she had wide access to people who claimed to be TT practitioners.
Emily took 21 TT practitioners and used them for her science experiment. She would take a TT practitioner, ask
them to extend their hands through a screen (through which they can't see). On the other side would be Emily,
who would flip a coin and put out either her left hand or her right hand, depending on the coin. The TT
practitioner would then have to correctly answer which hand Emily put out. Overall, through 210 samples, the
practitioner picked the correct hand 44% of the time.
Emily's main goal here was to test whether or not the TT practicioners guesses were random, like a flip of the
coin. In most medical experiments, this is the norm. We want to test whether or not the treatment has an effect,
not whether or not the treatment actually works.
We will now begin to formulate this experiment in terms of the terminology we learned in this course.
Question 2: What are the null and alternative hypothesis for Emily's experiment? Discuss with students around
you to come to a conclusion.
