Extraneous variables can be controlled through various methods, including random assignment, which ensures that participants are evenly distributed across different groups, minimizing bias. Standardizing procedures, such as maintaining consistent environments and instructions for all participants, helps reduce variability. Additionally, researchers can use control groups to compare results and statistical techniques to account for potential confounding factors. Lastly, pre-screening participants to match them on key characteristics can also help mitigate the influence of extraneous variables.

A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.

Scientisists do mant different controlled expirements to see different results. To conduct a fair expirement, you must control all of the variables expect for the one you are testing.
In qualitative research, researchers do not typically control variables in the same way as in quantitative research. Instead, they aim to explore and understand the complexities and nuances of a phenomenon without manipulating variables. The focus is on gaining in-depth insights and understanding the context in which the research is conducted.
One handy way to dodge a difficult question is to earnestly begin talking about something extraneous to it.
Variables are simply names used to refer to some location in memory - a location that holds a value with which we are working. It may help to think of variables as a placeholder for a value. in system

In an experiment, the conditions, variables, and procedures should closely resemble real-life situations to ensure the results are valid and applicable to the real world. This includes controlling for as many extraneous variables as possible and designing the experiment in a way that reflects the natural environment or scenario being studied.
