    total number of observation 

    add up all the numbers 

    5 + 3  + 7 + 3 + 3 + 5 =    26  

    Width of each class   = (29-21) = 8  

    but note:   the width of 8 includes 9 values 

    Midpoint 

    (21 + 29)/2  = 25 

    Modal Class is 30-38    

    (because 7 is the highest count)  

    Next Class 66-74
