In experimental research, you systematically intervene in a process and measure the outcome. The validity of your research will depend on your experimental design.To conduct an experiment, you need to be able to vary your independent variable, precisely measure your dependent variable, and control ...
In statistical research, a variable is defined as an attribute of an object of study. Choosing which variables to measure is central to good experimental design. Example If you want to test whether some plant species are more salt-tolerant than others, some key variables you might measure ...

Experiments Experiments are a type of research method that involve manipulating one or more variables in order to observe the effect on another variable. Experiments are often used to test cause-and-effect relationships. Case studies Case studies are a type of research method that involve an in-...
These studies do not include variables, which are elements of an experiment that are able to be manipulated. Research that incorporates variables seeks to prove or disprove changes and relationships as a result of the variable being manipulated. However, within descriptive research, the objective is...
Combining the two methods above, mixed methods research mixes elements of both qualitative and quantitative research methods, providing a comprehensive understanding of the research problem. We can further break these down into: Sequential Explanatory Design (QUAN→QUAL): This methodology involves conductin...

Conclusion Few randomized controlled trials and systematic reviews were among citation classics in the field of pediatrics. Articles that use observational research methodology, and are published in journals with lower impact factors, can become citation classics.Peer...
Reliable research aims to minimize subjectivity as much as possible so that a different researcher could replicate the same results. When designing the scale and criteria for data collection, it’s important to make sure that different people will rate the same variable consistently with minimal ...
the content of a test, survey or measurement method must cover all relevant parts of the subject it aims to measure. If some aspects are missing from the measurement (or if irrelevant aspects are included), the validity is threatened and the research is likely suffering fromomitted variable ...
