On **January 23, 2011**, after all the interviews had been conducted, viewed all the interviews: >>
 *  . I made a guess as to whether I thought they were lying or telling the truth in their test questions.
 * I then compared my guesses to the actual result of their coin toss. The data is shown below.


 * Names ||  Guess  ||  Result  ||
 * Patrick ||  Truth  ||  Truth  ||
 * Aidan ||  Truth  ||  Truth  ||
 * Jeff ||  Lie  ||  Lie  ||
 * Murphy ||  Lie  ||  Lie  ||
 * Tristin ||  Truth  ||  Truth  ||
 * Reilly ||  Lie  ||  Lie  ||
 * Megan ||  Lie  ||  Lie  ||
 * Tess ||  Truth  ||  Lie  ||
 * Mollie ||  Truth  ||  Lie  ||
 * Campbell ||  Lie  ||  Lie  ||
 * G. Kevin ||  Truth  ||  Truth  ||
 * Kevin ||  Truth  ||  Truth  ||
 * Dan ||  Lie  ||  Lie  ||
 * John ||  Lie  ||  Lie  ||
 * Douglas ||  Lie  ||  Lie  ||
 * Colleen ||  Lie  ||  Lie  ||
 * Alicia ||  Lie  ||  Truth  ||
 * Annette ||  Truth  ||  Lie  ||
 * Irene ||  Truth  ||  Truth  ||
 * Tina ||  Lie  ||  Lie  ||


 * On **January 17, 2011**, I analyzed the data and concluded:

-Through this experiment, it was proven that human lie detecting techniques are effective 80% of the time

-10 out of the 13 subjects who lied during the test questions exhibited a noticeable change in eye patterns, cadence of speech, body language, and emotional gestures.

-While certain indicators allowed me to notice a difference between the control and the test questions, every person is different and some subjects did not exhibit an extreme change in behavior when lying

-These results disproved my hypothesis because one cannot rely solely on human lie detecting techniques

-Although the accuracy of human lie detecting techniques are not 100% accurate, this experiment brings us one step closer to uncovering the truth
