Question

Answer this question with a formula. ​

Answer 1

Answer:

Step-by-step explanation:

Media n+1/2 = 9+1/2=5

Mean sum of all observation/ total number of observation

=54/9=6

Answer 2

Step-by-step explanation:

Given: 5,3,12,0,7,11,4,3,9

ascending order:0,3,3,4,5,7,9,11,12

$mean = \frac{sum \: of \: observations}{no. \: of \: observations}$

$mean = \frac{0 + 3 + 3 + 4 + 5 + 7 + 9 + 11 + 12}{9}$

$mean = 6$

$no. \: of \: digits \: is \: odd(9)$

$therefore \: median = \frac{ no. \: of \: digits + 1}{2}$

$median = \frac{10}{2} = 5th \: term$

$= 5$
