Given that fx 340 and N 20 find the arithmetic ... - JAMB Economics 2017 Question

Arithmetic mean, x̄= ∑fx

                                        n<br />

where:

x̄= Arithmetic mean

∑ = sum of

X = series of figures in a given data

f = nunmber of times a particular number occurs (frequency)

n = number of figures or element

From the question:

Since, x̄= ∑fx

                  N<br />

Then, x̄= ∑fx

                 N<br />

=(\frac{340}{20})

= 17
