How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
How do you calculate sample size?
Count up the number of obseravtions made on the experimental units. That is the sample size.
What are two ways that researcher can avoid a biased sample?
experimental and control groups
What is the difference between random sampling and random assignment?
Random assignment: assigning participants to experimental and control conditions by chance Vs. Random sample: a sample that fairly represents a population because each member has an equal chance of being included You decide :-D
Define sampling design?
Sampling is a method of selecting experimental units from a population so that we can make decision about the population. Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.

What does control as an experiment means?
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.

What is the number of animals used in an experimental study is called?
Sample Size
What are two ways that researcher can avoid a biased sample?
experimental and control groups
What is each sample does not necessarily have the same properties as every other sample?
You will typically have an experimental parameter that will be varied as part of testing a hypothesis.
What is the sample treated like other experimental groups except the variable is not applied?
The control group.
What Sample is treated like other experimental groups except the variable is not applied?
The control group.
What do you call a sample that goes through all the steps in an experiment but is not exposed to the experimental variable?
control
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
Sample treated like other experimental groups except variable is not applied?
Control Variable♪☆
A sample that is treated exactly like the other experimental groups except that the variable is not applied to it?
A control group.
