The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.

sample size refers to the collection of data by only a selected size of te population through the process of sample surveys and sampling methods used in collecting data.

The sample is a subset of the population. For example, the population may be all the people at your school. A sample might be 5 people from each class. There are different types of sampling methods. The most commonly used is a simple random sample. When your obtain data from the entire population this is called a census.

Inferential statistics.

A group of data is a sample.

There are Goodness-of-Fit tests that can be used. The choice of test will depend on what is known about the population and sample data.

Inferential statistical methods are used when data is collected from a sample in the population. Inferential statistics are used to generalize the results of the sample to the population. In a census you have data from each and every member of the population, so you just use descriptive statistics.

Inferential statistics.

statistical goodness of fit test used for categorical data to test if a sample of data came from a population with a specific distribution. It can be applied for discrete distributions.

When the sample - whether it is random or systematic - is somehow representative of the population.

This is called a sample statistic. These statistics are often used to give a general picture of a more specific whole.
