What else can I help you with?
If the size of the sample is increased the standard error?
If I have understood this very poorly worded question correctly, the answer is that the standard error may decrease. It cannot increase but it is possible that it does not decrease.
Is the standard error of the sample mean assesses the uncertainty or error of estimation?
yes
What is the sample size for standard deviation?
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.
How does sample variance influence the estimated standard error and measures of effect size such as are r2 and Cohen's D?
Sample variance directly influences the estimated standard error, as the standard error is calculated using the sample variance divided by the square root of the sample size. A higher sample variance results in a larger standard error, indicating greater uncertainty in the estimate of the population parameter. For effect size measures like ( r^2 ) and Cohen's D, increased sample variance can affect their interpretation; larger variance may lead to smaller effect sizes, suggesting that the observed differences are less pronounced relative to the variability in the data. Thus, understanding sample variance is crucial for accurate estimation and interpretation of effect sizes.
What is the standard error for the following proportion sample size of 25 and?
To calculate the standard error for a proportion, you can use the formula: [ SE = \sqrt{\frac{p(1 - p)}{n}} ] where (p) is the sample proportion and (n) is the sample size. If the proportion is not given in your question, you'll need to specify a value for (p) to compute the standard error. For a sample size of 25, substitute that value into the formula along with the specific proportion to find the standard error.
What happens to the standard error of the mean if the sample size is increased?
Decrease
What happens to the standard error of the mean if the sample size is decreased?
The standard error increases.
What happens to the sampling error when the sample size is increased?
It is reduced.
If the size of the sample is increased the standard error?
If I have understood this very poorly worded question correctly, the answer is that the standard error may decrease. It cannot increase but it is possible that it does not decrease.
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. 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.

How does one calculate the standard error of the sample mean?
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
What affects the standard error of the mean?
The standard error of the underlying distribution, the method of selecting the sample from which the mean is derived, the size of the sample.
Why is standard deviation of a statistic called standard error?
The standard error is the standard deviation divided by the square root of the sample size.
Is the standard error of the sample mean assesses the uncertainty or error of estimation?
yes
Describe how the sample size affects the standard error?
Standard error (which is the standard deviation of the distribution of sample means), defined as σ/√n, n being the sample size, decreases as the sample size n increases. And vice-versa, as the sample size gets smaller, standard error goes up. The law of large numbers applies here, the larger the sample is, the better it will reflect that particular population.
What is the value of the standard error of the sample mean?
The sample standard deviation (s) divided by the square root of the number of observations in the sample (n).
What is the sample size for standard deviation?
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.
