Scientific Method and Research
Scientific Method and Research
1. Find one peer-reviewed journal article (about anything at all) and hand it in with this
worksheet. You do not have to read it, but it MUST be from a credible scientific journal –
not a magazine article, web blog, facebook page, etc. Use the school library or Google
Scholar to help you find something. It is important that you know where to find valid
2. Using the steps for the scientific method as well as the elements of a controlled
experiment (slides 4 and 5), create hypothesis and experiment based upon your own
observations (even if it is something that you already know the outcome of). Do not
worry about creating data – simply state which type of data you would collect.
EX: I observe that after I drink soda, I get the hiccups. I hypothesize that the bubbles in
carbonated beverages likely result in burps or hiccups in most people. I can test this by
comparing the response of a large group of individuals to different drinks. I will have a
control group that will drink only water. The experimental group will drink carbonated water
(to attempt to control for all other substances in sodas and focus primarily on the bubbles).
The two groups will drink their specified drink at the same time of day, as close to the same
pace as possible, out of identical cups, and the same amount of fluid. They will be observed
for their response (hiccups or burps). This qualitative data will be analyzed to determine the
correlation between carbonation and hiccups/burps.

Multiple Chronic Conditions Among US Adults: A 2012 Update
Brian W. Ward, PhD, Jeannine S. Schiller, MPH, and Richard A. Goodman, MD, MPH
From 2001 through 2010, the prevalence of persons with multiple (≥2) chronic conditions
(MCC) in the United States increased; approximately 26% of US adults had MCC in 2010, when
10 different conditions (ie, hypertension, coronary heart disease, stroke, diabetes, cancer, arthritis,
hepatitis, weak or failing kidneys, asthma, and COPD) were considered (1). The large and growing
prevalence of MCC has prompted a spectrum of responses — including a national initiative calling
for better research and data on MCC — to address this clinical and public health problem (2–5).
In response to the need for ongoing surveillance of chronic conditions and to more frequently
monitor their prevalence, we analyzed data from the 2012 National Health Interview Survey
(NHIS) to produce updated estimates of single chronic conditions and MCC among the noninstitutionalized, civilian US adult population.
The NHIS is a multistage health survey of the US civilian, non-institutionalized population
(6,7). Information from the NHIS Family Core questionnaire (Family Core) on sex, race/ethnicity,
age, and health insurance coverage was used in this analysis. In the Family Core, 1 adult from the
family self-reports and acts as a proxy for other family members. Data on chronic conditions are
collected by using the Sample Adult Core questionnaire. The respondent (ie, “sample adult”) is
randomly selected from all adults in the family aged 18 years or older. A proxy is used for the
sample adult only if a health condition makes it impossible for the sample adult to respond for
himself or herself (6,7). Our analyses include 34,525 sample adults from the 2012 NHIS (final
response rate: 61.2%).
Adults were identified as having 0,...
