For different analysts or different laboratories using the same analytic methods, or a analyst from same laboratory using a variety of different principles of analytic methods, the method of hypothesis testing can be applied to quantitative analysis, to assess whether there are essentially differences in their experimental process. Research methods adopt normal P-P diagram, Kolmogorov-Smirnov one-sample test method, two independent samples Mann-Whitney test method, Runs test method. The initial tensile strength data from longitude direction and latitude direction of Alkali-resistant glass fiber mesh will be collected by experiment. The research results show that the quantitative analysis of experimental data through multi-angle can be used to evaluate whether the experimental operation have a significant difference on the experimental results. Thus laboratory management can be promoted through quantitative analysis of experimental data.
