A prediction for an observation or scientific problem that can be tested through experimentation

In nutrition we can measure
1) Body weight (BW)
2) Blood pressure (BP)
3) Heart rate (HR)
4) Blood cholesterol
5) etc.
***Just remember & understand that testimonies & opinions are not measurable***

An explanation of the observation after the hypothesis (prediction) has been tested & supported through rigorous (through) experimentation

1) Does that data seem too good to be true?
2) Who is providing the info, do they have something to gain, & who performed the study?
3) Are there other studies that support this info?

1) 1st, you observe something
2) 2nd, you form a hypothesis
3) 3rd, you conduct an experiment, 2-3+ times
4) 4th, you can form a theory

Scientists study nutrition through many different types of experiments

1) Epidemiological- A study that helps make observations between health & nutrition/diet
2) Experimental studies
1) Clinical trial- Within nutrition scientists explore the health effects of alternating peoples' diets
2) There are also animal studies, help to explore the effect of alternating animals' diets/nutrition
3) Biochemistry & molecular biology- Biochemistry & molecular biology are laboratory based techniques that are used to study nutrition functions within the body
***With experimental studies, it is very important to make sure data collected is reliable & quantified (measurable)***
