Answer 2

Hi.

Here is your answer---

_________________________

1--- For Direct Methods is---

      Mean = ∑fx ÷ ∑f
 Where,
 
   ∑f  =  Sum of all Frequencies.
  ∑fx = Sum of the Products of the Frequencies and Variate.


2---For Step -Deviation Method---

   Mean =  A + (∑ft ÷∑f) × i
   Where,
      A = Assumed Mean
      i = Largest number


3--For Short Cut Method---

  Mean = A + (∑fd ÷ ∑f)

Where,
  d = Deviation
     = x - A
  A = Assumed Mean
