What effect does varying the sample size and the size of the sample SD have on the shape of a sampling distribution?

Homework Answers

Answer #1

It seems that the sampling distribution has an almost perfect normal shape, even though the original data is skewed or slight skewed. The standard deviation of sampling distribution of mean = Population SD/Sqrt(n)

As sample sample size increases the standard deviation of sampling distribution of mean decreases while if increase the population SD, then standard deviation of sampling distribution of mean is also increased

As per central limit theorem, if the sample size increases, the sampling distribution of sample mean tends toward a normal distribution with mean is population mean and SD is Population SD/Sqrt(n)

1. what effect does increasing the sample size have on the population standard deviation? If the sample size increases then the sample standard deviation will be decreases. But in this sentence, it is not a sample standard deviation. Every answer in CheggStudy is decrease. I think sample size doesn't affect to the population standard deviation. 2.

explain the difference between creating a sampling distribution (i.e. plotting sample means or sample proportions in a probability distribution) vs. plotting individual data points. explain why it makes sense that increasing the sample size should decrease the standard deviation in a normal distribution. Explain what this does to the overall shape of the normal curve
