Correlation and regression as applied in green concrete research

• Broschiertes Buch

Produktbeschreibung

Correlation and regression were employed as analytical tools to study the degree of relationship as well as the nature and strength of the relationship between green concrete properties and percentage replacement of cement with civil engineering materials. The results of the correlation analysis showed that Pearson product-moment is a better method for analysing green concrete properties when compared with Spearman's correlation coefficient since Pearson's method takes cognisance of the actual data values unlike Spearman's use of data positions. The results of regression analysis also revealed that, for data whose trendline is polynomial in shape with the highest power of its assumed equation higher than that of quadratic equation, it is better to analyse such data using least square regression line method for linear relationship than least square regression line method for non-linear relationship.
