An experimental sample is an experiment that is just a sample of what you are looking for.
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
Count up the number of obseravtions made on the experimental units. That is the sample size.
experimental and control groups
A sample must be vacuum dried before the addition of the sample application buffer to remove any residual moisture that could interfere with the sample's behavior during analysis. Moisture can affect solubility, lead to inconsistent results, and cause unwanted reactions with the buffer components. Vacuum drying ensures that the sample is in a stable, concentrated form, allowing for more accurate and reproducible experimental outcomes. Additionally, it prevents dilution of the sample when the buffer is added, optimizing the effectiveness of the application.
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
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
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.

experimental and control groups
You will typically have an experimental parameter that will be varied as part of testing a hypothesis.
A sample treated like other experimental groups except that the variable is not applied is known as a control group. The control group serves as a baseline to compare the effects of the experimental variable on the treatment group. By not applying the variable, researchers can isolate its effects and determine if any observed changes in the experimental group are due to the variable itself. This helps ensure the validity of the experimental results.

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.
