According to some studies in rats, it can inhibit a fat producing enzyme called Citrate Lyase, making it more difficult for the body to produce fat out of carbohydrates (1). Other rat studies show increased levels of the neurotransmitter serotonin.
This could theoretically lead to reduced appetite and cravings (2).
The use of reliability and validity are common in quantitative research and now it is reconsidered in the qualitative research paradigm. Since reliability and validity are rooted in positivist perspective then they should be redefined for their use in a naturalistic approach. Like reliability and validity as used in quantitative research are providing .
Reliability is a necessary ingredient for determining the overall validity of a scientific experiment and enhancing the strength of the results. Debate between social and pure scientists, concerning reliability, is robust and ongoing.
Reliability and Validity. In order for research data to be of value and of use, they must be both reliable and valid.. Reliability. Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner. Reliability refers to the extent to which.
Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Validity is the extent to which the scores actually represent the variable they are intended to. Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.
