True or False A sampling distribution is a probability distribution for a statistic?
The statement is true that a sampling distribution is a probability distribution for a statistic.
What is sampling examine well known methods of probability and nonprobability sampling in statistic?
Non probability sampling and probability sampling are different because probability sampling uses random samples. Non probability sampling aren't random, but can still be representative of the population as a whole if done correctly.
When the population standard deviation is known the sampling distribution is known as what?
normal distribution
When the population standard deviation is known the sampling distribution is a?
normal distribution
How to reduce sampling error?
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.
The true sampling error is usually not known because?
the sample mean cannot be computed

What is probability sampling and non probability sampling?
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.
A test for genetic abnormalities that is performed between the 8th and 10th week of pregnancy is known as villus sampling CVS?
Chorionic villus sampling
Which of the following types of sampling is usually the most accurate?
Simple random
When the population standard deviation is known the sampling distribution is a?
normal distribution
What is the examination of cells retrieved from the edge of the placenta between the eighth and tenth weeks of pregnancy is known as?
chorionic villus sampling
What are advantages and disadvantages in cluster sample?
Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.

What is the difference between the sample mean and the population mean known as?
Sampling bias.
