There are all sorts of , including random sampling. It is, therefore, important that the sample accurately represents the population.

Recently, many text summarisers are been freely delivered on the Internet, and you can you use them on-line. Each division develops one of the stages needed to make the whole main point. However, not all students will have scored 65 marks. Range, , absolute deviation, and variance are all examples of measures of variability.

A Chi-Sqaure or a T-Test tells you the probablility that the results you found in the group you studied are representative of the population that group was chosen to represent.
