Question

What is the mean of the data set? 17, 24, 26, 13

Answer 1

$Given \: data : 17, 24, 26 , 13$

$We \: know \:that ,$

$\boxed {\pink { Mean = \frac{ Sum \: of \: the \: terms }{ Number \: of \: terms } }}$

$\implies Mean = \frac{ 17 + 24 + 26 + 13 }{4} \\= \frac{ 80}{4} \\=20$

Therefore.,

$\red { Mean \: of \: the \: data } \green { = 20}$

Answer 2

Given ,

The data set is 17 , 24 , 26 , 13

We know that ,

The mean or average value of data is given by

$\large \rm \fbox{Mean = \frac{Sum \: of \: observation}{Number \: of \: observation} }$

Thus ,

Mean = 80/4

Mean = 20

$\therefore \underline{ \rm{The \: mean \: of \: the \: given \: data \: set \: is \: 20}}$
