Nutrition BIO105 lab 8
NUTRITION AS A SCIENCE
In this lab you will be researching the process and steps involved in the SCIENTIFIC METHOD. You will need to determine which sources of Nutrition Information are reliable and credible. In addition you will identify, use and understand a survey as a tool to obtain knowledge concerning health and eating habits of a population subgroup. You will also evaluate data collected in a wellness survey.
What characteristics are associated with a sound research study?
What is a hypothesis? List the specific characteristics that should be included in a well-written hypothesis.
What is meant by the term Subject Bias? List a couple of possible examples where you might suspect Subject Bias.
Find an article about a recent âNew Diet Discoveryâ. What aspects about the article and author should you look for to determine if the article contains credible information? Which of these aspects where found in your article? Which were not? Please list the examples of these aspects as they were found in your article.
List 3 positives and 3 negatives about using the internet to obtain nutrition information.
A SURVEY is a tool used to collect information about a population. List 2 strengths and 2 weaknesses of this tool.
Explain the difference between validity and reliability.
Explain NHANES and BRFSS.
DESIGNING YOUR OWN NUTRITION EXPERIMENT
Just like other scientific disciplines, factual nutrition information is based on experimental research that has been replicated many times by different scientists. Below, you will construct a realistic intervention study, using human volunteers, to answer a nutrition related question of your choice. Be sure to include as much detail as possible.
Your Question to be tested:
State your hypothesis concerning your above listed question.
In testing your hypothesis, who will you recruit for your experiment? (Include things like age, gender, health status and the total number of subjects)
Briefly explain your experimental protocol. (Give as much detail about what you will do with your experimental subjects)
What variables will you test for? (What things are you going to measure?)
How do you plan to limit the subject bias? (How will you prevent your volunteers from reporting effects simply because they know they are participating in your experiment?)
What limitations do you foresee in carrying out this experiment?
