Application of the fast SAS Macros for balancing

... Example 1. We first select a sample with equal probabilities 1/5, balanced on the socio-demographic variables quoted in Table 1 (18 variables) and on a constant for the condition of fixed sample size. We use the first landing option. A sample of 5,294 units is drawn in a few seconds. Results are pre ...

... When expressing the value of a probability, either give the exact fraction or decimal or round off final decimal results to three significant digits. (Suggestion: When a probability is not a simple fraction such as 2/3 or 5/9, express it as a decimal so that the number can be better understood.) All ...

Step #2: (Mean) Add all the values in the data set and then divide by the number of items. Step #3: (Median) Identify the middle number. ( ...

... Take care when reporting results. It is not a good idea to regard a 5% level of significance, i.e. a p-value of 0.05, as an absolute cut off value. Report results according to size of pvalue. For example, evidence of an effect is : • almost conclusive if p-value < 0.001 and could be said to be stron ...

History of statistics

The History of statistics can be said to start around 1749 although, over time, there have been changes to the interpretation of the word statistics. In early times, the meaning was restricted to information about states. This was later extended to include all collections of information of all types, and later still it was extended to include the analysis and interpretation of such data. In modern terms, ""statistics"" means both sets of collected information, as in national accounts and temperature records, and analytical work which requires statistical inference.Statistical activities are often associated with models expressed using probabilities, and require probability theory for them to be put on a firm theoretical basis: see History of probability.A number of statistical concepts have had an important impact on a wide range of sciences. These include the design of experiments and approaches to statistical inference such as Bayesian inference, each of which can be considered to have their own sequence in the development of the ideas underlying modern statistics.
