Sports Statistics Application Of Some Important Statistics

From the application perspective, this article together with the intuitive language this sample, variation, overall, inferred, risk five aspects such important statistical thinking, and points out that these commonly used statistical methods in understanding the thought and method problems that should be paid attention to in the application, which contain his statistics reflect the basic principle, also used statistical methods of practical value. Overall thought was clear research object, by research purpose of the operationalization processing, research object more specific, actual problem modeling and general characteristics of quantization, make clear goal, building, users with statistical method actual problems between the bridge; Sample thought is partly reflect the overall, sampling is about general information collection, and statistics of the sample information is extracted, and put forward a random sample theoretical prerequisite is statistical inference method, but also the essential characteristics of statistical inference; Data variation thought is use data to measure of factors variation, data variation was used to measure the size of the size of the factors measure, decomposition of variation is an important means to analyze the factors of variable control that cannot be neglected in the experimental design; Infer that thought refers to the overall, by sample inference small probability principle is the theoretical basis of the statistical inference, statistical distance, maximum likelihood and projection is statistical inference method; the important thought tools Face the risk of statistical results, statistical processing results is always accompanied by risk, reliability test, protect the null hypothesis, even was forced to accept the null hypothesis, is to reduce the risk of statistical inference method.
