【Abstract】 Reviewing the history of three large sampling distributions,it was important as a measurement tool,which is widely used in practice. The more intuitive,more specific structural expression distribution is used to built structural expressions of three large sample distributions,the relationship among the three integrates mutually through graphic analysis.更多还原
