What are the purpose of a design specification when designing and manufacturing a product?
Purpose of a Design Specification
How a experimental design could be improved?
An experimental design can be improved by ensuring proper randomization to eliminate bias, which helps create more reliable results. Additionally, increasing sample size can enhance the statistical power of the study, making it easier to detect significant effects. Implementing a control group can also provide a clearer comparison against the experimental group, while refining the operational definitions of variables ensures that measurements are accurate and consistent. Lastly, conducting a pilot study can help identify any potential issues before the full-scale experiment.
What is the difference between experimental and ex post facto research design?
Ex-post facto research measures the cause and effect relationship without manipulating the independent variable. While the experimental research starts from manipulating and controlling the independent variables and proceeds to observing the effect on the dependent variables.
When was Experimental Breeder Reactor I created?
Experimental Breeder Reactor I was created in 1950.
What are the elements of good experimental design?
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 studiedThe five components of experimental design are:-Independent Variable-Dependent Variable-Constant Variables-Control group-Number of Repeated TrialsGood 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 purpose of blocking in experimental design is?
the control for multiple variables in a experiment
Blocking in experimental design is useful because it?
controls for multiple variables in an experiment.
What is the difference between strata and blocks in statistics?
Blocking is more for experimental design while strata is for survey sampling.
Why is experimental design a key factor in science inquiry?
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
Can you give you a sentence using experimental design?
The next car show will have an example of our experimental design.
What is a blocking variable?
A blocking variable is a variable that is included in a statistical analysis to account for the effects of that variable on the outcome of interest. By including a blocking variable, researchers can control for potential confounding factors and ensure that the relationship being studied is accurately captured. Blocking variables are commonly used in experimental design to improve the precision and validity of study results.

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.
