Upper bound 150 has nothing to do with the average as you can see in above mentioned formula. 0 votes 0 votes A_i_$_h commented Sep 13, 2017 reply Follow Share thanku :) 0 votes 0 votes Akash Verma 1 commented Sep 17, 2017 reply Follow Share Assume, marks of 7 students in a subject is given out of 100 68 , 72 , 75,62,75,80,68 then, avg = (sum of number/ total number ) * 100 = ((68+72+75+62+75+80+68) / 700) * 100 = 71.429 if given out of 150 then , avg = (sum of number/ total number ) * 150 = ((68+72+75+62+75+80+68) / 1050) * 150 = 71.429 A = average (or arithmetic mean) n = the number of terms (e.g., the number of items or numbers being averaged) x1 = the value of each individual item in the list of numbers being averaged 1 votes 1 votes Please log in or register to add a comment.
