This document outlines the components of an experimental design, including stating a testable question and hypothesis, describing the independent and dependent variables, assigning team member duties, outlining procedures, collecting and presenting results in a data table and graph, and drawing a conclusion based on the evidence. It provides a template for planning and documenting a scientific experiment.

1. Heart rate during laughter. Laughter is often called “the best medicine,” since studies have
shown that laughter can reduce muscle tension and increase oxygenation of the blood. In the
International Journal of Obesity (January 2007), researchers at Vanderbilt University investigated
the physiological changes that accompany laughter. Ninety subjects (18 – 34 years old) watched
film clips designed to evoke laughter. During the laughing period, the researchers measured the
heart rate (beats per minute) of each subject with the following summary results: �̅� = 73.5, s = 6.
(NOTE: �̅� and s denote the mean and standard deviation, respectively). It is well known that the
mean resting heart rate of adults is 71 beats/minute. At ∝ = 0.05, is there sufficient evidence to
indicate that the true mean heart rate during laughter exceeds 71 beats/minute?

3. Earnings of Mexican street vendors: Detailed interviews were conducted with over 1,000 street
vendors in the city of Puebla, Mexico, in order to study the factors influencing vendors’ incomes
(World Development, February 1998). Vendors were defined as individuals working in the street,
and included vendors with cars and stands on wheels and excluded beggars, drug dealers, and
prostitutes. The research collected data on gender, age, hours worked per day, annual earnings,
and education level. A subset of these appear in ...
