What is observational study?
in vivo
What will a scientist never do in an observational study?
In an observational study, a scientist will never draw attention to himself or herself. They will also not attempt to randomize a study.
What are the difference between an experiment and an observation?
In an experiment investigators apply treatments to experimental units (people, animals, plots of land, etc.) and then proceed to observe the effect of the treatments on the experimental units. n an observational study investigators observe subjects and measure variables of interest without assigning treatments to the subjects. The treatment that each subject receives is determined beyond the control of the investigator. For example, suppose we want to study the effect of smoking on lung capacity in women. Summary: 1.The main difference between observational study and experiments is in the way the observation is done. 2.In an experiment, the researcher will undertake some experiment and not just make observations. In observational study, the researcher simply makes an observation and arrives at a conclusion. 3.In observational study, no experiment is conducted. In this type of study the researcher relies more on data collected. 4.In an experiment, the researcher observes things through various studies. 5.There is human intervention in experiments whereas there is no human intervention in observational study. 6.Hawthorne studies are a good example for experiments. 7.The study to determine the relation between smoking and lung cancer is a typical example for observational study.
In an observational study researchers try not to?
Influence the people in the study
A study that involves no researcher intervention is called?
An observational study.
Is a survey an experimental study?

Is the study experimental or observational A sample of fish is taken from a lake to measure the effect of pollution from a nearby factory on the fish?
observational
If a researcher wanted to be behind a one-way mirror to watch how preschool children behave naturally he would be doing?
Observational study
What is a superior observational study?
If we're talking about statistics: There is no superior observational study, each study has its advantages and disadvantages.
What is cofounding factor in epidemiology?
confounding factor is defined as the hidden or the factor which distorts the the experimental unit since it difficult to control ,but in case of epidemiology , the factor that alawys involve in experimental and observational study , which is emphasized or focused on life.
What is observational study?
in vivo
What are the parts of descriptive research?
Descriptive research includes observational methods, case study methods, and survey methods. They are used to describe situations instead of make predictions about them.
