Why is having a larger sample size be a better idea than having a small sample size when doing a experiment?
1. Better chance of uniform sample. 2. Material for confirmations if needed.
Does the size of a sample affect the values of the frequency table?
Yes. If the sample is a random drawing from the population, then as the size increases, the relative frequency of each interval from the sample should be a better estimate of the relative frequency in the population. Now, in practical terms, increasing a small sample will have a larger effect than increasing a large sample. For example, increasing a sample from 10 to 100 will have a larger effect than increasing a sample from 1000 to 10,000. The one exception to this, that I can think of, is if the focus of the study is on a very rare occurrence.
What is domain sampling in statistics?
It's a model for measuring reliability of measures of a construct. First you choose randomly a finite number of items from an infinite pool of items to measure the construct and then use it as a criterion to evaluate reliability of other chosen samples. The higher the correlation of the scores derived using any random sample with the score derived using the criterion sample, the higher the reliability of the random sample
Why does a statistical sample have to be large?
The larger the sample of data collected leads to a more accurate conclusion.
How does sample size affect the experiment?
The sample size determines the accuracy of results in an experiment
Why would having a larger sample size be a better idea than having a samll sample size when doing an experiment?
less bias and error occur when sample size is larger
How does sample size affect the margin of error?
The larger the sample size, the smaller the margin of error.
Which experiment most likely has greater reliability and why?
The experiment with a larger sample size is likely to have greater reliability because it provides more data points to observe trends and patterns, reducing the impact of random variability. Larger sample sizes also increase the likelihood of obtaining more precise and accurate estimates of the true population parameters.

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.
Does sample size affect survey result?
Yes, sample size can significantly impact survey results. A larger sample size generally provides more representative and reliable results compared to a smaller sample size. With a larger sample size, the margin of error decreases, increasing the accuracy of the findings.
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.
How does sample size affect the size of your standard error?
The standard error should decrease as the sample size increases. For larger samples, the standard error is inversely proportional to the square root of the sample size.The standard error should decrease as the sample size increases.

Why would a CBC specimen be rejected?
A CBC specimen may be rejected due to specimen hemolysis (breakdown of red blood cells), inadequate sample volume, clotted specimen, improper handling or storage, or outdated sample. These factors can affect the accuracy and reliability of the test results.

Is it true that the larger the sample of a mineral the greater its density?
No, the density of a mineral remains constant regardless of the size of the sample. Density is an intrinsic property of the mineral and is determined by its composition and structure. It is typically expressed in units of mass/volume, so a larger sample will have a proportionally greater mass and volume, resulting in the same density.
