MEASURES OF CENTRAL TENDACY THE TOTAL ADVERTISING. 

Scene 1

MEASURES OF CENTRAL TENDACY THE TOTAL ADVERTISING

Mean: x = Ʃfx n Where x = midpoint of a class f = frequency of class n = Ʃf (number of entries in sample) Mean: x = Ʃfx n = 1077.5/150 = 7.18 (the mean of the total advertising budget was approximately 7.18). 

Scene 2

Mean: x =   Ʃfx                          n Where x = midpoint of a class                 f = frequency of class                 n =  Ʃf  (number of entries in sample)             Mean: x =   Ʃfx                       n     =   1077.5/150      =  7.18 (the mean of the total advertising budget was approximately 7.18)

Median = Mm = ∫+ (n/2-cf/f)h = 0+ (150/2-0/83) 6 = 5.42. 

Scene 3

Median = Mm =  ∫+ (n/2-cf/f)h      =  0+ (150/2-0/83)  6     = 5.42

Mm =  ∫+ (n/2-cf/f)h    Where I = lower limit of median class                 n= number of observations          cf = cumulative frequency of class preceding the median class                     f  = frequency of median class                h = class size (assuming class size to be equal)

mod⁡e=L_m+[Δ_1/Δ_1+Δ_2 ]×c. = -0.5 + ⌊83/83-45⌋6 = 132.

Mm = ∫+ (n/2-cf/f)h Where I = lower limit of median class n= number of observations cf = cumulative frequency of class preceding the median class f = frequency of median class h = class size (assuming class size to be equal).
