Question

what Is the formula for arithmetic mean median mode

Answer 1

here's the formula in explanation :-

first add up (sum) all of the data values (x) and then divide the result by the number of values (n). obtain the following formula for the mean (¯x). The median value of a set of data is the middle value of the ordered data.

Answer 2

heya

here is your answer

MEAN:

DIRECT METHOD:
          mean(x)= ∑dx/∑f
        assumed mean method (x)=a + (∑fd/∑f) , where d = x-a
        step deviation method (x) = a+h(∑fu/∑f) , where u = x-a/h

MEDIAN: 
             = l +(n/2-cf/f)h

MODE:
         =l+(f1-f0/2f1-f0-f2)h

hope it helps
