Question

what is mean of discrete observation of y1 y2..... yn?

Answer 1

Mean $=\frac{y_1+y_2+........+y_n}{n}$

Step-by-step explanation:

Given observation $y_1,y_2,.......,y_n$

Number of observation = n

$mean = \frac{\textrm{sum of observation }}{\textrm { number of bservation} }$

           $=\frac{y_1+y_2+........+y_n}{n}$

Answer 2

mean = $\frac{\sum_{i=1}^{n}y_i}{n}$

Step-by-step explanation:

discrete observation of y1 y2..... yn

the mean of the observation is calculate by the formula

i.e

$\frac{y_1+y_2+y_3....y_n}{n}$

where y1+y2+...yn  is the sum  of all the observations

and

n is the number of observations

then ,

the formula becomes

mean = $\frac{\sum_{i=1}^{n}y_i}{n}$
