What is the variable setup in an experiment called?
The variable setup in an experiment is called the experimental design. This design includes all the factors and conditions that are manipulated or controlled in the experiment to test the research hypothesis.
What is the definition of experimental research?
Experimental research is a method of scientific investigation that involves manipulating variables to study cause-and-effect relationships. It typically involves establishing control over variables, random assignment of participants, and the use of an experimental design to test hypotheses. The goal is to determine the effect of the independent variable on the dependent variable while minimizing the influence of extraneous factors.
What does a test group mean in biology?
A test group in biology refers to the group being experimented on or tested in a study. It is the group that is exposed to the variable being tested, allowing researchers to compare its outcomes to those of the control group, which is not exposed to the variable. This experimental design helps researchers determine the effect of the variable being studied.
In order to reduce bias scientists usually prefer experiments that lead to what kind of results?
Scientists usually prefer experiments that yield objective and consistent results, which are reproducible and not influenced by researcher bias. By using a controlled experimental design and randomization techniques, scientists can minimize bias and increase the reliability of their findings.
Why is replication in experimental design?
Observed results are less likely to be affected by random chance.
In an experimental design the variable the researcher has control over and that is different for the treatment and control groups is called the?
Explanatory variable apex

What is a indenpent variable?
In experimental design there are two variables, the independent variable and the dependent variable. You are allowed manipulate or change one variable to see how that affects results in an experiment you are conducting. Think of it as the variable Ican change. This is the i variable, the independent. The experiment will generate data that responds to these changes. This data is your dependent variable.
A condition or a situation that is manipulated in a experimental design is called?
It's called a variable
What is the definition of dependent variable?
A variable in a research design that is free to change over a range of different experimental treatments. You have probably made a hypothesis that the dependent variable will change in some systematic way as the experimental treatments change. Examining the data that you generate will tell you whether or not your hypothesis is right.Term used in regressionanalysis to represent the element or condition that is dependent on values of one ormore other independent variables.Basically a dependent variable is an scientific term mostly used in science projects.Dependent variable means an variable that is changed by the expirment.
What is a quasi experimental design?
A quasi-experimental design is a research method that resembles an experimental design but lacks the element of random assignment to groups. This means that the groups are not formed randomly, making it less able to establish causation between variables. It is often used when true experimentation is not feasible due to ethical, logistical, or practical reasons.
What principles of experimental design ensures that the explanatory variable and not some variable over which the experimenter has no control is causing observed changes in the res?
Control
What is the purpose of an chart?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
What does an IVCDV chart mean?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
What happens when more than one variable in an experiment is changed at a time?
When more than one variable is changed at a time in an experiment, it becomes difficult to determine which variable is responsible for any observed effects. This can lead to confounding variables and make it challenging to draw meaningful conclusions from the data. It is best practice in experimental design to change only one variable at a time to accurately assess its impact.
What is a Quasi Research Design in Research methodology?
A quasi-experimental research design is a type of research methodology that lacks full experimental control but still allows for comparison between groups. It involves manipulating an independent variable to observe its impact on a dependent variable, but lacks random assignment to groups. This design is often used when true experimentation is not feasible or ethical.
What is an example of non experimental research design?
Pre-experimental research designs are research designs that are characterized by a lack of random selection and assignment.
