What is the reason for the background music ? It is not assisting me to listen and learn the information that is presented about the correlation coefficient.

I had to create scatter diagram for age and anxiety % and I got a correlation coefficient of -0.0195676 but my scatter diagram the points are random and don’t show a negative correlation so how would I describe such data ?

Hi... With a correlation coefficient so close to zero (-0.0196), the correlation is very weak-- too weak to say that anxiety is affected by age.

Thanks but reduce the volume of music so the lesson can be free of distraction. You did awesomely
