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 ?

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.
