Examples of elementary statistics
Essentially, parameters are unknown and the main game of statistics is to try to estimate parameters on the basis of small samples collected from the population. Definition 3. A quantitative measure of a sample data is called a statistic. So, any constant that we compute from a sample is a statistic.Example 1.4 (Descriptive and Inferential Statistics). Consider event of toss-ing dice. The dice is rolled 100 times and the results are forming the sample data. Descriptive statistics is used to grouping the sample data to the fol-lowing table Outcome of the roll Frequencies in the sample data 1 10 2 20 3 18 4 16 5 11 6 25Five to seven items are usually used in the scale. The scale doesn’t have to state “agree” or “disagree”; dozens of variations are possible on themes like agreement, frequency, quality and importance. For example: Agreement: Strongly agree to strongly disagree. Frequency: Often to never. Quality: Very good to very bad.
