Speaking Of Statistics
Findings from statistical studies as stated by Bennett and Briggs are:
• Smoking increases the risk of heart disease.
• Eating margarine can increase the risk of heart disease.
• One glass of wine per day can protect against heart disease but increases the risk of breast cancer.
• Potato chips and sugary sodas are the foods most strongly associated with weight gain.
the findings that came from the Harvard Nurses’ Health Study conducted
over the next 10 to 20 years the most important results are that nurses
that responded to the questionnaires
said that the study has helped them to pay more attention to how they
live their lives (Bennett & Briggs, 2012, pg. 44). I believe that
the findings above have already altered my lifestyle as a result of them
and I am really proud to say that I quitted smoking
about six months ago.
The Harvard Nurses` health Study is an observational study because
“in anobservational study, we observe or
measure specific characteristics while trying to be careful to avoid
influencing or modifying the characteristics we are observing”
(Bennett & Briggs, 2012, pg.19). In this study researchers used questionnaires to observe findings but didn`t try
to influence responses given. In contrast the purpose of an experiment is to study the effects of some treatment”
& Briggs, 2012, pg.19). A practical and ethical way to gather
similar data would be by carrying out blood tests to measure cholesterol
levels, hormone levels, etc. Researchers should
be concerned about that fact that only 120,000 of the original 370,000
questionnaires were returned because not even half of the nurses gave a
response. This would probably mean that these nurses are not leaving a
healthy lifestyle, but we don`t know for sure.
A lot of the issues about personal health are also sensitive material
and often people and especially healthcare providers are not ready to
share facts that may affect other people opinion about them.
do believe that dishonesty could be leading researchers to incorrect
conclusions because if for instance most of the nurses interviewed would
have lied, than results would been
inconclusive. All the participants in the Harvard Nurses` Health Study
were women nurses. The study didn’t include men. I don’t think men can
be included in the study because the study was about the effects of
