Statistical studies in which researchers do not control variables of interest are uncontrolled experimental studies [C]. It refers to the variable in an experiment which could harm the connection between independent and dependent variables.
Further explanation
:
An uncontrolled experimental study is a part of statistics. It means you conduct research that its object uninfluenced by anything or anyone. This distinguishes importantly from a controlled study in which a researcher defines and limits all parameters and variables concerned.
Regardless of the type of research conducted, there are three types of variables commonly used in an experiment, they are:
• Independent variable
The independent variable is the factor that you deliberately modify or regulate to see what effects it has. For example: in research to determine the impact of temperature on plantation pigments, the independent variable (cause) is temperature, while the quantity of pigment color is the dependent variable (the effect)
• Dependent variable
This refers to the variable being tested in research. It is ‘dependent’ on the independent variable. It is the one to be measured when you are taking data in research. For example: in research to find the best chicken that produces the largest eggs, here the dependent variable is the egg size. Because it depends on the breed of chicken (the independent variable).
• Constant variable
Constant variable or also known as the controlled variable is a variable that may vary, but the experimenter deliberately keeps constant so that the relationship between the independent and the dependent variable is more clearly isolated.
