What are the variables in a plan and design paper chromatography lab?
responding variable-distance of components( Rf values)
Why is publishing the design and results of an experiment considered an essential part of science?
when one particular variable is manipulated in a given set of variables, the result should always be the same. In keeping with this assumption, scientists expect to test one another's investigations.
What is the difference between natural group design and matched group design?
Natural group designs: A type of independent groups design in which the conditions represent the selected levels of a naturally occurring independent variable, for example, the individual differences of variable age. Researchers use natural groups designs to meet the first two objectives of the scientific method: description and prediction.· Individual differences (or subject variables) are selected rather than manipulated; represents a type of correlational research in which researches look for covariations between natural groups variables and dependent variables;· Causal inferences cannot be made regarding the effects of natural groups variables because plausible alternative explanations for group differences exist.Matched group designs:A type of independent groups design in which the researcher forms comparable groups by matching subjects on a pretest task and then randomly assigns the members of these matched sets of subjects to the conditions of the experiment. Matched group designs are a good alternative when neither the random groups design nor the repeated measures design can be used effectively.
What did William Harvey use correlational design to discover?
Correlational design is a procedure where two variables are measured, without manipulation, to determine if there is a relationship. He used correlational design to describe, in detail, the systematic circulation and properties of the blood.
What is the vocabula word for testing a hypothesis by using carefully controlled steps?
experimental research design

A condition or a situation that is manipulated in a experimental design is called?
It's called a variable
Write short note on experimental reserach 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.
What is cad drafting?
CAD ( Computer aided design) Uses software to simulate a design of an object on a computer. Which can be changed and manipulated easily before you send off the final design.
Are there independent or dependent variables in qualitative research?
i want to know the role of variables of the qualitative design
