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 purpose of running a control sample or a DNA ladder with your sample?
Running a control sample or a DNA ladder alongside your sample serves several important purposes. It allows for the verification of the experimental conditions and the accuracy of the results, ensuring that the assay is functioning properly. A DNA ladder provides a reference for size estimation, enabling the determination of the fragment sizes in the sample. Overall, these controls enhance the reliability and interpretability of the experimental data.
What happens to experimental probability values when you increase the sample size why this is true?
As the sample size increases, experimental probability values tend to converge towards the theoretical probability. This is due to the Law of Large Numbers, which states that as the number of trials increases, the average of the results obtained will get closer to the expected value. Larger sample sizes reduce the impact of random fluctuations and provide a more accurate representation of the underlying probabilities. Consequently, the experimental results become more reliable and consistent with theoretical predictions.

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 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 a sample treated like other experimental groups except that the variable is not applied?
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.
What do you call a sample that goes through all the steps in an experiment but is not exposed to the experimental variable?
control
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.
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.
