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: Experimental research is guided by educated guesses that guess the result of the experiment. An experiment is conducted to give evidence to this experimental hypothesis. Experimental research, although very demanding of time and resources, often produces the soundest evidence concerning hypothesized cause-effect relationships.

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 design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.
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
Which part of an investigation is only found in an experimental investigation?
The part of an investigation that is only found in an experimental investigation is the manipulation of an independent variable. In experimental investigations, researchers deliberately change the independent variable to observe the effect on the dependent variable. This manipulation allows for the establishment of cause-and-effect relationships, which is a key component of experimental design. Control over the independent variable is a defining feature of experimental investigations that sets them apart from other types of research designs.
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?
Because you want to see how the experimental results change due to only that one variable change. If you used two variables, and the results varied, how would you know which variable contributed more to the change if at all? It can be done this way, but one variable at a time will allow you to make sense of your data much more efficiently.
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.
