These notes are free to use under Creative Commons license CC BY-NC 4.0.A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic.It might not be a very precise estimate, since the sample size is only 5. Example: Central limit theorem; mean of a small sample. mean = (68 + 73 + 70 + 62 + 63) / 5. mean = 67.2 years. Suppose that you repeat this procedure 10 times, taking samples of five retirees, and calculating the mean of each sample.

Market-leading author Marty Triola's approach is readable and visual, featuring flowcharts throughout that simplify and clarify more complex concepts and procedures.The relative frequency of a data class is the percentage of data elements in that class. The relative frequency can be calculated using the formula f i = f n f i = f n, where f f is the absolute frequency and n n is the sum of all frequencies. n n is the sum of all frequencies. In this case, n = 4+2+1+ 2 = 9 n = 4 + 2 + 1 + 2 = 9.

However, there’s a shortcut to finding 5 choose 3. The combinations formula is: nCr = n! / ( (n – r)! r!) n = the number of items. r = how many items are taken at a time. The ! symbol is a factorial, which is a number multiplied by all of the numbers before it. For example, 4! = 4 x 3 x 2 x 1 = 24 and 3! = 3 x 2 x 1 = 6. 1.1 The Five Basic Words of Statistics 1.2 The Branches of Statistics 1.3 Sources of Data 1.4 Sampling Concepts 1.5 Sample Selection Methods One-Minute Summary Test Yourself E very day, you encounter numerical information that describes or analyzes some aspect of the world you live in.
