Scientific Inquiries in Nutrition
Overview:
Scientific Inquiries in Nutrition. Many important findings about nutrients have been made through scientific research. Additionally, The scientific process involves making observations, developing hypotheses (predictions) about observations, testing hypotheses through experiments, evaluating results, and drawing conclusions based on evidence. Also For this assignment, you will read How Science Works (https://undsci.berkeley.edu/lessons/pdfs/how_science_works.pdf) and the The Science Learning Center then address the items below.
Cite all sources in a standard citation format (APA, MLA, other). Cited sources are worth 10 points.
Spelling, grammar, and punctuation are worth 5 points.
Answers must be in your own words. Be sure to use college-level paraphrasing skills. To learn more about paraphrasing, see this link: https://www.umgc.edu/current-students/learning-resources/writing-center/online-guide-to-writing/tutorial/chapter5/ch5-10.html
Define the terms below in your own words. Hypothesis, Independent variable and Dependent variable, Controlled (control) variable. Randomized trial, Double-blind study.
Short Answer.
Answer the items below in your own words: Explain how the independent variable relates to the dependent variable in an experiment. Also Explain how a controlled (control) variable is different from an independent variable. However, Define correlation as it relates to an observation. Also Provide an example of data results where there is a correlation between the variables.
Additionally, Define causality as it relates to experimental design and experimental results. Also Define in your own words and use the terms ‘independent variable’ and ‘dependent variable’ as part of your definition. Lastly, Provide an example of data results where there is a causal relationship between the variables in an experiment. True or False: A hypothesis statement does not need to mention the effect of the independent variable on the dependent variable. Hence Explain the reasoning for your answer.
