Strength: It is easier to replicate (i.e. copy) a laboratory experiment. This is because a standardized procedure is used. Strength: They allow for precise control of extraneous and independent variables. This allows a cause and effect relationship to be established.
What is lab based study?
(LA-bruh-tor-ee STUH-dee) Research done in a laboratory. A laboratory study may use special equipment and cells or animals to find out if a drug, procedure, or treatment is likely to be useful in humans. It may also be a part of a clinical trial, such as when blood or other samples are collected.
Which nutrient is classified as a micronutrient?
Micronutrients are compounds that are only required in minimal amounts which aid in the growth, development, and maintenance of the body. The most common micronutrients are vitamins and minerals (e.g., iron, zinc, vitamins A, D, E, and K).
What is a weakness of lab experiments?
Demand characteristics – participants aware of experiment, may change behaviour. Artificial environment – low realism. May have low ecological validity – difficult to generalise to other situations. Experimenter effects – bias when experimenter’s expectations affect behaviour.
What could be a weakness of an experiment?
Weaknesses: The main weakness of the experimental method is their dependence on what many see as an “artificial” environment. People may behave differently in the experimental setting than they would under more ordinary conditions.
What is a weakness of an epidemiological study group of answer choices?
What is a weakness of an epidemiological study? Results from animal studies cannot be applied to human beings. Code of ethics prevent certain treatments. The list of possible causes of disease is difficult to narrow down.
What is a weakness of an epidemiological study?
The major weakness of epidemiologic studies is. inability to experimentally establish cause and effect. Additional factors that can affect the relationship between physical activity and blood cholesterol, such as smoking, body fat, and so on, are called. confounding factors.
What is a strength of laboratory based studies quizlet?
Strength of Laboratory-based studies. -Can control conditions. -Can determine effects of a variable. Weaknesses of Laboratory-based studies. -Cannot apply results from test tubes or animals to human beings.
Which of the following is a disadvantage of correlational research quizlet?
Which of the following is a disadvantage of correlational research? It provides ambiguous interpretations of causes and effects.
What are the advantages and disadvantages of field experiments?
Here are the advantages and disadvantages of a field experiment. Greater ecological validity than laboratory experiment.
Fewer demand characteristics if participants are unaware.
Lack of control brings problem of extraneous variables.Difficult to replicate.Difficult to record data accurately.Ethical problems.
Why is a lab experiment reliable?
– Results of laboratory experiments tend to be reliable, as the conditions created (and thus results produced) can be replicated. – Variables can be measured accurately with the tools made available in a laboratory setting, which may otherwise be impossible for experiments conducted ‘in the field’ (field experiments).
Whats does fiber do?
Fiber is a type of carbohydrate that the body can’t digest. Though most carbohydrates are broken down into sugar molecules, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested. Fiber helps regulate the body’s use of sugars, helping to keep hunger and blood sugar in check.
Is a balanced diet?
A balanced diet is a diet that contains differing kinds of foods in certain quantities and proportions so that the requirement for calories, proteins, minerals, vitamins and alternative nutrients is adequate and a small provision is reserved for additional nutrients to endure the short length of leanness.
What are three unhealthy eating behaviors?
Reflect:
Eating too fast.Always cleaning your plate.Eating when not hungry.Eating while standing up (may lead to eating mindlessly or too quickly)Always eating dessert.Skipping meals (or maybe just breakfast)
What are the disadvantages of laboratory observation?
One disadvantage in a laboratory observation is that the behavior of the participant might not be the same was it would be in a natural setting. For example, I did not have the opportunity to drink water while I was being observed.
What is a weakness of a quasi experiment?
The greatest disadvantage of quasi-experimental studies is that randomization is not used, limiting the study’s ability to conclude a causal association between an intervention and an outcome.
