Is this an example of an experimental study or of a nonexperimental study?
Non-experimental research is the type of research that lacks an independent variable. Instead, the researcher observes the context in which the phenomenon occurs and analyzes it to obtain information.

Unlike experimental research, where the variables are held constant, non-experimental research happens during the study when the researcher cannot control, manipulate or alter the subjects but relies on interpretation or observations to conclude. This means that the method must not rely on correlations, surveys, or case studies and cannot demonstrate an actual cause and effect relationship. Characteristics of non-experimental researchSome of the essential characteristics of non-experimental research are necessary for the final results. Let’s talk about them to identify the most critical parts of them.
Types of non-experimental researchNon-experimental research can take the following forms: Cross-sectional research: Cross-sectional research is used to observe and analyze the exact time of the research to cover various study groups or samples. This type of research is divided into:
Longitudinal research: In a longitudinal study, researchers aim to analyze the changes and development of the relationships between variables over time. Longitudinal research can be divided into:
When to use non-experimental researchNon-experimental research can be applied in the following ways:
Advantages and disadvantagesSome advantages of non-experimental research are:
Among the disadvantages of non-experimental research are:
Non-experimental research is based on the observation of phenomena in their natural environment. In this way, they can be studied later to reach a conclusion. Difference between experimental and non-experimental researchExperimental research involves changing variables and randomly assigning conditions to participants. As it can determine the cause, experimental research designs are used for research in medicine, biology, and social science. Experimental research designs have strict standards for control and establishing validity. Although they may need many resources, they can lead to very interesting results. Non-experimental research, on the other hand, is usually descriptive or correlational without any explicit changes done by the researcher. You simply describe the situation as it is, or describe a relationship between variables. Without any control, it is difficult to determine causal effects. The validity remains a concern in this type of research. However, it’s’ more regarding the measurements instead of the effects.

What is a Nonexperimental study example?For example, nonexperimental studies establishing that there is a relationship between watching violent television and aggressive behaviour have been complemented by experimental studies confirming that the relationship is a causal one (Bushman & Huesmann, 2001).
What are examples of experimental and Nonexperimental research design?Examples of experimental research are laboratory experiments that involve mixing different chemical elements together to see the effect of one element on the other while non-experimental research examples are investigations into the characteristics of different chemical elements.
What makes a study experimental or Nonexperimental?In experimental studies the researcher sets up the environment and carefully controls the variables s/he is interested in. Non-experimental research takes place in a real-life setting, and it is not possible for the researcher to control all possible variables.
What is a Nonexperimental study design?Nonexperimental designs include research designs in which an experimenter simply either describes a group or examines relationships between preexisting groups.
