Statistical methods for analyzing agroecological data might not be able to help agroecologists to solve all of the current problems concerning crop and animal husbandry, but such methods could well help them assess, tackle, and resolve several agroecological issues in a more reliable and accurate manner. Therefore, our goal in this article is to discuss the importance of statistical tools for alternative agronomic approaches, because alternative approaches, such as organic farming, should not only be promoted by encouraging farmers to deploy agroecological techniques, but also by providing agroecologists with robust analyses based on rigorous statistical procedures.

This graduate work approaches the study of Statistical Process Control - SPC, in a stage production of an industrial frame, aiming to use the tool of statistical process control (SPC) to assess the process capability. Where the process needs improvement as well not meet the specifications. Assessing the needs that the company needs to improve quality management, and the difficulties they present during the implementation of the CEP. The present study is to use the method of case study. The results are presented through study of the level of defects using Pareto diagrams and control chart by - (p) fraction defective, and checking the capacity and stability of the process using control charts and histograms XbarraR.
