    Calculating the Mean from a Frequency

    Distribution

     

    Number of alcoholic beverages consumed by a sample of college students last weekend. (This data is fictitious.)

     

    x
    value

    f
    (frequency)   

    f(x)
    multiply
    0 5 0
    1 10 10
    2 5 10
    3 10 30
    4 5 20
    10 2 20
    Sum: 37 90

     

     

    Step 1.  Multiply f(x)

    Step 2.  Sum f, Sum f(x)

    Step 3: f(x)/n:   90/37=2.43
