Am one of those who have struggled with Unit 7 but am grateful to the tutor for reiterating the importance of ethics and professionalism and encouraging us to utilise skills from previous modules. Had to listen to a few videos on youtube on how to do multiple regression analysis via excel and thereafter aced the assessment. I was simply not applying my mind to it and once l did the assessment after refreshing via the videos it was much more understandable. It is indeed a joy and fulfilling to have done it myself. All the best.
