I need to figure out if 57 people took a survey and 3 of them scored a (3), 31 of them scored a (4) and 23 of them scored a (5), what was the average score and how did you figure that out?

  • Math -

    total score = 3(3) + 31(4) + 23(5) = 248

    avg score = 248/57 = 4.35


    (visualize the following:
    3+3+3+4+4+....+4+5+5+...+5 )
