一、2015年6月-2016年6月产量比较根据相关的统计分析软件知,2015年6月至2016年6月重点民营企业粗钢月产量和钢材月产量线性相关系数为0.921,有着显著的正相关性,即增减变化为同向的。关联性的结论:如果粗钢月产量每增加或减少1万吨,则钢材月产量增加或减少1.159万吨。2015年6月至2016年6月,粗钢和钢材月日均产量的线性相关系数为0.880,有着显著的正相关性,即增减变化为同向的。关联性的结论:如果粗钢月日均
I. Comparison of output from June 2015 to June 2016 According to the relevant statistical analysis software, the linear correlation coefficient between monthly crude steel output and monthly steel output of key private enterprises from June 2015 to June 2016 was 0.921, showing significant Positive correlation, that is, changes in the same direction. Conclusions of relevance: If the monthly crude steel output is increased or decreased by 10,000 tons, the monthly steel output is increased or decreased by 11,500 tons. From June 2015 to June 2016, the linear correlation coefficient of monthly output of crude steel and steel was 0.880, which showed a significant positive correlation, that is, the change of the increase and decrease was the same direction. Relevance conclusion: If crude steel is on average daily
