, which are covered in this document.
What type of study is a survey?
Survey research is
a quantitative approach
that features the use of self-report measures on carefully selected samples. It is a flexible approach that can be used to study a wide variety of basic and applied research questions.
What is a good example of an observation?
Scientific Observation Examples
A scientist looking at a chemical reaction in an experiment
. A doctor watching a patient after administering an injection. An astronomer looking at the night sky and recording data regarding the movement and brightness of the objects he sees.
What is observation in simple words?

the active acquisition of information from a primary source
. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity.

.
What is the main difference between an experiment and an observational study?
In an observational study,
we measure or survey members of a sample without trying to affect them
. In a controlled experiment, we assign people or things to groups and apply some treatment to one of the groups, while the other group does not receive the treatment.

What are the strengths and weaknesses of observational research?
| Strengths: Weaknesses: | More natural behaviour occurs if people are unaware of observation. Observer may affect behaviour if detected. | Studying of animals that cannot be observed in captivity. Difficult to replicate – cannot control extraneous variables. |
