The standard error of the mean decreases as the sample size ( n ) increases because it is calculated as the standard deviation of the population divided by the square root of the sample size (( SE = \frac{\sigma}{\sqrt{n}} )). As ( n ) increases, the denominator grows larger, leading to a smaller standard error. This reflects the idea that larger samples provide more accurate estimates of the population mean, reducing variability in the sample means. Consequently, with larger samples, we can expect more precise estimates of the true population mean.
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.
As the sample size increases, the standard deviation of the sample mean, also known as the standard error, tends to decrease. This is because larger samples provide more accurate estimates of the population mean, leading to less variability in sample means. However, the standard deviation of the population itself remains unchanged regardless of sample size. Ultimately, a larger sample size results in more reliable statistical inferences.
The margin of error decreases as the sample size ( n ) increases because a larger sample provides more information about the population, leading to more accurate estimates of population parameters. This increased accuracy reduces the variability of the results, thereby narrowing the confidence interval. Mathematically, the margin of error is inversely proportional to the square root of the sample size, meaning that as ( n ) increases, the margin of error decreases. In essence, larger samples yield more reliable data, resulting in a smaller margin of error.
The standard deviation of the sample means is called the standard error of the mean (SEM). It quantifies the variability of sample means around the population mean and is calculated by dividing the population standard deviation by the square root of the sample size. The SEM decreases as the sample size increases, reflecting improved estimates of the population mean with larger samples.
When we increase sample size the standard deviation( error) will be decrease and the nagetive skewness is converting to normality. shabirahmad666@rocketmail.com

it should decrease
The standard error increases.
Decrease

true
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.
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.
The width of the confidence interval willdecrease if you decrease the confidence level,increase if you decrease the sample sizeincrease if you decrease the margin of error.
The standard error of the underlying distribution, the method of selecting the sample from which the mean is derived, the size of the sample.
