相关性是另一种方法，用来对15种不同型号的打印机的价格和其他变量进行统计分析。相关性也是衡量变量之间关系的有用指标。这种方法对于确定变量之间是强相关还是弱相关，是正相关还是负相关都是非常有用的，这对于得出一个合适的结论是非常重要的(Anderson, Sweeney and Williams, 2010)。因此，本分析研究拟采用相关法确定所选因素对打印机价格的影响。利用SPSS软件对15台打印机采集的数据进行分析和显示。在本分析中，使用SPSS进行相关分析和多元回归分析是合适的。与其他数据分析方法相比，SPSS能够更快地获得有效的输出结果。

除此之外，使用SPSS进行数据分析的好处还包括选择范围广、输出表示更好和数据管理更有效(Longnecker and Ott, 2008)。利用SPSS，将自变量和因变量同时考虑得到皮尔逊相关矩阵。由上述相关矩阵可知，当价格与文本速度(-0.383)、文本成本(-0.501)、彩色照片时间(-0.518)、彩色照片成本(-0.263)变量相关时，皮尔逊系数为负。另一方面，当文本成本与文本速度相关时，Pearson系数的值为正(0.030);彩色照片时间及文字速度(0.035);彩色照片成本及文字速度(0.224);彩色照片时间及文字成本(0.408);彩色照片成本和文字成本(0.606)，彩色照片时间和彩色照片成本(0.081)。

Correlation is another method that selected to perform a statistical analysis on price and other variables related to 15 different models of printers. Correlation is also a useful measure of relationship between variables. This method is quite useful to determine that variables are correlated strongly or weakly as well as in positive or negative manner, which is significant to draw an appropriate conclusion (Anderson, Sweeney and Williams, 2010). Due to this reason, correlation method is planned to use in this analytical study to determine the impact of selected factors on the price of printers.SPSS is used to analyse and present collected data on 15 printers. In this analysis, the use of SPSS is appropriate to perform correlation analysis and multiple regression analysis. As compared to other data analysis methods, SPSS is relatively more effective to obtain valid output quickly.

Along with this, wide range of option, better output presentation and effective data management are also some benefits of using SPSS for data analysis (Longnecker and Ott, 2008). By using the SPSS, the Pearson correlation matrix is produced by including both independent and dependent variables.The above correlation matrix shows that the values of Pearson coefficient in case of correlation of price with text speed (-0.383), text cost (-0.501), colour photo time (-0.518) and colour photo cost (-0.263) variables are negative. On the other hand, the value of Pearson coefficient is positive in case of correlation between text cost and text speed (0.030); colour photo time and text speed (0.035); colour photo cost and text speed (0.224); colour photo time and text cost (0.408); colour photo cost and text cost (0.606), and colour photo time and colour photo cost (0.081).
