When you apply the same treatment to more than one experimental unit the process is called?
Replication occurs when each treatment is applied to more than one experimental unit.

What is a treatment in statistics quizlet?
Treatment. Any combination of the values of the factors. Experimental unit. A person, object, or some other well-defined item upon which a treatment is applied in an experiment.
What is a condition applied to the experimental units involved in an experiment?
Term. Treatment. Definition. A condition applied to the experimental unit.
What is experimental unit in research?
experimental unit, in an experimental study, a physical entity that is the primary unit of interest in a specific research objective. Generally, the experimental unit is the person, animal, or object that is the subject of the experiment.
What is experimental treatment in research?
1. in research, the conditions applied to one or more groups that are expected to cause change in some outcome or dependent variable. 2.
What is the definition of treatment in statistics?
The term “statistical treatment” is a catch all term which means to apply any statistical method to your data. Treatments are divided into two groups: descriptive statistics, which summarize your data as a graph or summary statistic and inferential statistics, which make predictions and test hypotheses about your data.
What is confounding quizlet?
Confounding: basic definition. A mixing of effects between the exposure, the outcome and a third extraneous variable known as a confounder.
What is control in statistics?
If a process produces a set of data under what are essentially the same conditions and the internal variations are found to be random, then the process is said to be statistically under control.
What is experimental unit and treatment?
Treatment - The combination of experimental conditions applied to an experimental unit. ◆ Response - The outcome being measured. ◆ Experimental unit - The unit to which the treatment is applied.
What is treatment condition?
A treatment condition is characterized by having one specific value of the independent variable. The dependent variable is observed and measured to determine if it changes at different levels of the independent variable.
What is experimental object?
In an experiment, the experimental units are the objects subjected to specific experimental con- ditions. If the experimental units are humans, they are called subjects. The specific experimental conditions are called treatments.
What is confounding in a study?
Confounding in a study occurs when the effects of two or more explanatory variables are not separated. Therefore, any relation that may exist between an explanatory variable and the response variable may be due to some other variable or variables not accounted for in the study.
What is a designed experiment?
A designed experiment is when a researcher assigns individuals to a certain group, intentionally changing the value of an explanatory variable, and then recording the value of the response variable for each group.
Why is a study considered an experiment?
the study is an experiment because the researchers control one variable to determine the effect on the response variable. For a poll of voters regarding a referendum calling for a national railways development program, design a sampling method to obtain the inviduals in the sample. Be sure to support your choice.
How did the researchers control the experiment?
The researchers controlled the experiment by first clearing the ten tanks of all nonmosquito larvae, nymphs, and fish so that only mosquito larvae were left in the tanks. In this way the researchers attempted to make the tanks as identical as possible, except for the treatment.
Is neither study superior to the other?
Neither study is always the superior to the other. Both have advantages and disadvantages that depend on the situation. Is the value a parameter or a statistic. The value is a statistic because the 6,076 adults in public rest rooms is a sample.
