Find the median of:
233, 173, 189, 208, 194, 204, 194, 185, 200 and 220.
उत्तर
Firstly arrange the numbers in ascending order
173, 185, 189, 194, 194, 200, 204, 208, 220, 233
Median =`1/2 [ "value of"( "n" / 2 )^"th" "term" + "value of" (( "n" )/(2) + 1)^"th" "term" ]`
=`1/2 [ "value of"( 10 / 2 )^"th" "term" + "value of" (( 10 )/(2) + 1)^"th" "term" ]`
= `1/2[5^"th""term"+6^"th""term"]`
= `1/2 [ 200 + 194 ]`
= `1/2 [ 394 ]`
= 197
Thus the Median is 197.
