Why it is difficult to control extraneous variables in class rooms?

Extraneous variables are any variables other than the independent variable (the experimental variable) that can affect the real-world situation, with multiple uncontrollable variables that can affect the outcome of any experimental manipulation. These include the different personality, intellectual, and motivational qualities of the individual students in the various classes and the nature and quality of their interactions. Added to this is the fact that each class has a different teacher, whose own personal teaching style may influence the outcome. Some of these extraneous variables can be statistically controlled by the use of techniques like analysis of covariance, but this may be of limited value in a small scale intervention.


What are the different variables during an experiment?

categorical variablesquantitative variablesordinal variablesthere are more common ones like...Controlled/constant variable-Variables that do not change at all!Manipulated/independent variable-Variables that change (intentionally) in order to see their effect on another variable.Responding/depending variable-Is measured quantitatively or qualitatively and is affected by the independent variables.Hope this helps.


How many variables are tested during an experiment?

There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.


What controlled variables in science?

The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.


What is the controlled variables in an experiment?

Dependent Variable

What are extraneous and confounding variables?

Extraneous variables are factors other than the independent variable that can influence the dependent variable, potentially skewing the results of an experiment. Confounding variables are a specific type of extraneous variable that is related to both the independent and dependent variables, making it difficult to determine the true effect of the independent variable on the dependent variable. Both types of variables can threaten the internal validity of a study if not properly controlled.

What are the three variables that play an important role in a Practical Investigation?

Independent Variables, Dependent Variables and Extraneous Variables.


What variables did you have to control in order to get a valid result?

We controlled the independent variable (the variable we manipulated) to observe its effect on the dependent variable (the variable we measured). We also controlled for any potential confounding variables that could influence the results. Additionally, we ensured consistency in experimental conditions to eliminate any extraneous variables that could impact the outcome.


Why is it important to use a controlled experimentTHIS IS FOR APEX LEARNING?

Scientists use controlled experiments because they allow for precise control of extraneous and independent variables. This allows a cause-and-effect relationship to be established. Controlled experiments also follow a standardized step-by-step procedure.

What is a variable that interferes with other variables in a study called?

extraneous variable


What are the possible variables?

Possible variables can include independent variables, which are manipulated in experiments, and dependent variables, which are measured outcomes. Other types include controlled variables, which are kept constant to ensure a fair test, and extraneous variables, which could unintentionally affect results. Additionally, categorical variables represent distinct groups, while continuous variables can take on a range of values. Identifying and managing these variables is crucial for accurate research and analysis.

In an experiment what are controlled variables?

Controlled variables are quantities that must remain constant.

What are the elements of experiments and what kinds of variables are there?

The elements of experiments include the independent variable (manipulated by the researcher), dependent variable (outcome being measured), control group (not exposed to the independent variable), and experimental group (exposed to the independent variable). Variables can be independent (controlled by the researcher), dependent (measured to see the effect of the independent variable), or extraneous (unintended variables that can affect the results).
