摘要
对于三个率比较的x^2检验,其中间率的不同取值对x^2值的影响规律是:当中间率稍小于最小、最大两个率之和的1/2时,x^2值最小;偏离这两个率之和的1/2较大时,x^2值增大。应用这一规律有一定的实际意义。
On the χ~2-test of three sample rates,the smallest and the largest rates were given. The value of χ~2 is least when the middle rate is slightly less than the half of the sum of the smallest rate and the largest one, otherwise the value of χ~2 increases. The application of this principle can be helpful to data analysis.
