builds on previous research
-describes all steps in procedure clearly and completely
-describes all data to be collected
-keeps all variables, except the one being tested, the same
-includes a control (or placebo) for comparison -uses an appropriate group of subjects
-may include a large sample size
-may include multiple trials
-can be reproduced by other investigators to give -similar results
-respects human and animal subjects
*Elements may vary, depending on the problem being studied
The five components of experimental design are:
-Independent Variable
-Dependent Variable
-Constant Variables
-Control group
-Number of Repeated Trials
Good Experimental Design is Simple;
1. simple in Concept ( no complex ideas)
2. simple in execution (not complex to do)
3. simple to replicate (repeat by others)
4. simplest complete result.

The four properties to a good experiment are idea.
"Basic definitions of the elements of design is where it makes things better,the basic things that can be seen such as visual elements and visual effects ways to make an impression,it a way to fool the eye of people."

The basic elements of good conservatory design are often neglected. However, the main basin element of a good conservatory design is the design of a structure.
with a good idea of the expected experimental results.
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
The next car show will have an example of our experimental design.
Experimental research design involves manipulating one or more variables in a controlled setting to observe the effect on the dependent variable. It allows researchers to establish cause-and-effect relationships by controlling for potential confounding variables. This design is characterized by random assignment of participants to different conditions and the use of control groups to minimize bias and increase the internal validity of the study.

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.
