Observational studies observe natural phenomena without intervention, while experimental studies manipulate variables to determine cause and effect. Observational studies are useful for understanding associations, while experimental studies can establish causal relationships between variables. Experimental studies involve random assignment of participants to groups, while observational studies rely on natural groupings.

Methods of study in psychology?
Some common methods of study in psychology include experimental research, surveys, case studies, and observational studies. Experimental research involves manipulating variables and measuring their effects on behavior. Surveys collect data from a large sample of participants through questionnaires. Case studies involve in-depth analysis of a single individual or group. Observational studies involve observing and recording behaviors in natural settings.
Are observational studys reliable?
Observational studies can provide valuable insights, but they have limitations. They can suggest associations between factors, but cannot prove causation. Factors like confounding variables and biases can impact the reliability of observational studies. It is important to interpret their results cautiously and consider other types of studies for more robust evidence.
Why are observational studies useful when studying children?
Observational studies allow researchers to directly observe children's behaviors and interactions in natural settings. This method can provide valuable insights into real-life behavior, reactions, and development without the constraints of a lab setting. Observational studies can help researchers understand how children learn, interact, and develop in everyday contexts.
What is psychoanalytic observational studies?
Psychoanalytic observational studies involve closely observing individuals' behaviors, thoughts, and emotions within a psychoanalytic framework to gain insights into the unconscious motivations underlying their behaviors. These studies aim to understand the development of personality, relationships, and mental health through the lens of psychoanalytic theory pioneered by Freud. Observational methods such as free association, dream analysis, and transference play key roles in these studies.
How is a controlled experiment different from an observational study?
In a controlled experiment, researchers manipulate variables to observe their effect on outcomes, while in an observational study, researchers observe natural variations in variables without manipulating them. Controlled experiments allow for stronger causal inferences compared to observational studies because they can establish cause-and-effect relationships.
How are observational studies of population different from experimental studies?

What are the different types of scientific investigations?
The different types of scientific investigations include descriptive studies, experimental studies, observational studies, and theoretical studies. Descriptive studies aim to describe a phenomenon, experimental studies involve manipulating variables to test hypotheses, observational studies involve observing and analyzing data without intervening, and theoretical studies involve developing and testing models or theories.
What is the difference between experiment?
An experiment is a controlled procedure used to test a hypothesis, whereas an observational study involves observing and recording data without intervening. Experimental studies involve manipulating variables, while observational studies do not involve manipulation and only observe existing conditions. Experimental studies are used to establish cause-and-effect relationships, while observational studies can only show correlation.
What are the three research methods typically used by ecologists?
The three research methods typically used by ecologists are observational studies, experimental studies, and modeling. Observational studies involve gathering data from natural environments without manipulating variables. Experimental studies involve manipulating variables to test hypotheses. Modeling involves creating mathematical or computer models to simulate ecological processes.
What is the science of observing and describing organisms in their environment paired with experimental science?
That would be ecology. Ecology is the branch of biology that studies how organisms interact with each other and their environment, including observational and experimental approaches to understand these relationships.
What are the two main types of data a scientist collect?
Data will be either qualitative (non numerical description) or quantative (numerical values assigned to a property). To give you an example, a meterologist may describe the sky on a particular day as cloudy (qualitative) with a 5 mile per hour wind (quantative). Studies can be classified as experimental studies or observational studies. The experimental study means that the scientist is able to treat or alter in some way the population. Medical studies of drugs frequently conduct experimental studies and collect experimental data. Observational studies, we collect data without altering the population. A good example is astronomical studies, where it is impossible to alter the population. Scientific studies need to be thorough investigations relying on good data and sufficient quantity of data in order to reach conclusions.

What are the Methods of psychological studies?
Psychological studies can use various methods, including experiments, surveys, observational studies, case studies, and interviews. Each method has its strengths and limitations, and researchers choose the most appropriate method based on their research question and goals. Experimental studies involve manipulating variables to observe their effects, while surveys gather data through questionnaires or interviews. Observational studies involve observing and recording behaviors in natural settings, case studies focus on in-depth analysis of individuals or small groups, and interviews involve direct interaction with participants to gather information.
In what studies do scientists not interfere with what is going on?
In observational studies, scientists do not interfere with the natural order of events and simply observe and analyze what is happening. This allows researchers to study phenomena in their natural state without influencing outcomes.
Are observational studys reliable?
Observational studies can provide valuable insights, but they have limitations. They can suggest associations between factors, but cannot prove causation. Factors like confounding variables and biases can impact the reliability of observational studies. It is important to interpret their results cautiously and consider other types of studies for more robust evidence.
Disadvantages of obsevation in data collection?
Surveys or studies that involve collection of data can be categorized as either observational or experimental. The experimental study occurs in a very controlled environment where some treatment is applied to the subjects. Data collection measures the change in some attributes of subjects after treatment. Wikipedia terms observational studies as "uncontrolled experimental studies." See related link. Observational studies can be more difficult as follows: 1. The controlled environment may be missing. Suppose I am asking people if they like a particular product. Some may have used this product, others may have heard bad things about it from friends. The influences can be numerous. 2. The means of obtaining a representative sample may be complicated. Suppose I am interested in determining if a particular pollutant is causing any harm. I would go to an area where the pollutant was the highest and examine people complaining of problems. Perhaps other pollutants are higher in this particular area. I have confounding problems. 3. The observational study often suffers from an inability to do "identical, repeated trials" as it does not initiate a particular treatment. This inability can result in erroneous conclusions, particularly when data is scarce and develops over time. This is particularly true in epidemiology studies, where the area to be studied and the time required to reach a conclusion depend on the phenomena being studied. If the disease is changing with time, it may be impossible to reach a conclusion even after many incidences have occurred. Does this mean we should just rely on experimental data? No, because in many areas which involve spatial analysis (astronomy, mining of minerals, epidemiology), experiments are not possible. Many disease studies depend on both experimental data and observational surveys.
