How does sample size affect the experiment?
The sample size determines the accuracy of results in an experiment
What happens to the crtitical value for a chi square test if the size of the sample is increased?
The size of the sample should not affect the critical value.
How do sample size confidence level and standard deviation affect the margin of error?

What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
How does sample size affect the experiment?
The sample size determines the accuracy of results in an experiment
Does sample size affect survey result?
a larger the sample size will reduce the size of the confidence interval
How does sample size affect the margin of error?
The larger the sample size, the smaller the margin of error.
Does uranium 238 have the shortest half life?
The half life of 238U is 4,468.109 years; this is a very long halflife !
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.
How does increasing the sample size affect the sample error of the mean?
It should reduce the sample error.
What are the elements that affect determination in a sample size?
Margin of error, level of significance and level of power are all elements that will affect the determination of sample size.
Why do smaller populations need larger sample sizes?
They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
What happens to the crtitical value for a chi square test if the size of the sample is increased?
The size of the sample should not affect the critical value.
How might choosing a small sample size affect a scientific investigation?
Statistically the results will not be scientifically valid if the sample size is too small.
How does the beginning sample size affect the accuracy of half-life dating?
A big sample is more statistically significant.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
