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.
In statistics which is better large sample size or small sample size?
Generally, the larger the sample the more reliable the results. Example: If you flipped a coin twice and got heads both times you could say the coined is biased towards heads. However, if you repeat the experiment 100 times your results will be a lot more reliable.
The best most reliable sampling technique is the one that has the smallest chance of unknowingly producing biased results in a study?
Convenience sample Systematic sample Simple random sample (SRS) Census
Why is sample size important in determining probability?
The bigger the sample size the more accurate the results will be. For example, if you roll a 6 sided die and track the results to get the probability of rolling a six. If you only roll 6 times, then you may not even get one 6 or you could get a few. A small sample size means you won't get very reliable results.
How do you ensure less sample bias?
The sample should be selected randomly.
What are the strengths of an experimental design?
a strength of an experimental design can be the sample size. having a large sample size eliminates some falty results or fulked results. also controlling all varibles except the independent is importent
What is a experimental sample?
An experimental sample is an experiment that is just a sample of what you are looking for.
How did Mendel's large sample size make his results more reliable?
it made his actual results approach the results predicted by probability.

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.

Convenience sample Systematic sample Simple random sample (SRS) Census
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.
Why is it important to ensure that an experimental sample is totally random?
To ensure that the results produced from your sample are fair and true. For example, if you had to pick 10 random numbers between 1 and 6, you could just say numbers that come into your head, but that wouldn't be random because you're choosing the numbers. A more random and fair way would be to roll a die 10 times and use those numbers, because you are in no way picking the numbers.

The bigger the sample size the more accurate the results will be. For example, if you roll a 6 sided die and track the results to get the probability of rolling a six. If you only roll 6 times, then you may not even get one 6 or you could get a few. A small sample size means you won't get very reliable results.
How will you ensure validity and reliability of data?
To ensure validity and reliability of data, market researchers can present the same surveys to different respondents within the same sample area. Using a wider sample area will also give a true picture of the results.
How do you calculate sample size?
Count up the number of obseravtions made on the experimental units. That is the sample size.
