是有一定规律的,比如经典例子:掷硬币.再比如分子热运动.以此研究者定义了"随机现象". 随机现象:个别实验结果呈现不确定性,大量重复实验又具有统计规律性的现象.而数学上研究此规律的学科叫做概率论(Theory of Probability 美 / ˌprɑːbəˈbɪləti),来解释随机现象统计规律性....
First Edition users testify that the book is well written and expertly documented. The reader is introduced to provocative "pointers" such as the relevance of graphs, the meaning of interpretation, Henry Ford's Code of Practice, and Deming's 14 points, among others....

4. (Statistics) statistics a statistic obtained by multiplying each possible value of a variable by its probability and then taking the sum or integral over the range of the variable adj 5. intermediate or medium in size, quantity, etc 6. occurring halfway between extremes or limits; average...
It starts with the original meaning of "probability" in statistics in the Ars Conjectandi by Jakob (James) Bernoulli, and the ensuing misunderstanding which gave the term its present meaning. One chapter is about robustness theory, its use of (nonadditive) Choquet-capacities, and an attempt to ...
Probability of not seeing any supercar in the period of 60 minutes is: = (0.7) ^ 3 = 0.343 Hence, the probability of seeing at least one supercar in 60 minutes is: = 1 − P(Not seeing any supercar) = 1 − 0.343 = 0.657 59. What is the meaning of sensitivity in statistics...

Yet research documents poor understanding of probability in the general public and suggest that people do not update their estimates about future events when given additional information. This may point to the difficult nature of Bayesian thinking, the framework that would allow rational decision makers...
However, the teaching of statistics and probability in mathematics classes has been criticised as not really ‘fitting in’, for several reasons, but chiefly the fact that statistical thinking presents notable differences from purely mathematical considerations. Thus, observing statistics under a mathematic...
