What is the difference between strata and blocks in statistics?
Blocking is more for experimental design while strata is for survey sampling.

What is a blocking variable in statistics?
Blocking is a technique (procedure) that is used in biological / agricultural field experiments to arrange experimental units in groups or blocks that are similar to one another. It is an attemp to improve comparisons of treatments. Blocking will reduce the source of variability and increase precision (and may be accuracy) The theoritical basis of blocking is represented b the following mathematical results. Given X and Y are random variables VAR(X-Y)=VAR(X)+VAR (Y)-2 COV(X,Y) Phendukani Hlatshwayo (M.Sc Agronomy, Candidate from South Africa)

What is experimental error and an example of what this error is?
An experimental error is is
What purpose of blocking in experimental design is?
Blocking in experimental design serves to control for variability among experimental units by grouping similar units together. This helps to isolate the effects of the treatment by reducing the influence of extraneous factors. By ensuring that each treatment is tested under similar conditions, blocking increases the precision of the experiment and enhances the reliability of the results. Ultimately, it allows for a clearer interpretation of the treatment effects.
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.
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.
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 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 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.
