The control group consists of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter. This group of scientific control enables the experimental study of one variable at a time, and it is an essential part of the scientific method.The control group consists of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter.

Why a control group is important in an experiment?
Control groups are an important aspect of true experimental designs. The presence of control groups allows researchers to confirm that study results are due to the manipulation of independent variables (IVs) rather than extraneous variables.
Why is a control group important in an experiment quizlet?
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variables effects on the experiment and can help rule out alternative explanations of the experimental results.
Why do we need a control group?
In a scientific study, a control group is used to establish a cause-and-effect relationship by isolating the effect of an independent variable. Then they compare the results of these groups. Using a control group means that any change in the dependent variable can be attributed to the independent variable.
What is the role of a control in an experiment quizlet?
The role of a control in an experiment is to provide a basis of comparison to the experimental group. During a controlled experiment, a scientist isolates and tests a single variable.
What is the definition of a control group in an experiment?
Control group, the standard to which comparisons are made in an experiment. A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
What is the definition of a control in an experiment?
In scientific experiments, a scientific control is one in which the subject or a group would not be tested for the dependent variable(s). The inclusion of a control in an experiment is crucial for generating conclusions from the empirical data. The use of controls allows to study one variable or factor at a time.
