Learn the four ways that regres­sion con­tributes to the DMA­IC approach, the three caveats for using the pre­dic­tive capa­bil­i­ty of regres­sion, the three main types of regres­sion analy­sis, and con­sid­er­a­tions for select­ing the right approach for a spe­cif­ic project.

Next Video How to Perform a Correlation Study 

A cor­re­la­tion study aims to mea­sure the strength and direc­tion of the lin­ear rela­tion­ship between two vari­ables. It’s often used in explorato­ry research to find poten­tial rela­tion­ships between vari­ables. Learn the dif­fer­ence between cor­re­la­tion and cau­sa­tion, how to use Pearson’s r to deter­mine the cor­re­la­tion coef­fi­cient, and the steps to con­duct­ing this study.
