Hi,
Median is a measure of central tendency
which gives the value of the middle-most
observation in the data.
Finding the median of ungrouped data:
______________________________
Wr first arrange the data values or
observations in ascending order.
Then,
i ) if n is odd ,
Median = [( n + 1 ) /2 ]th observation.
ii ) if n is even ,
Median = average of the ( n/ 2 ) th and
[ ( n /2 ) + 1 ]
••••••••••••••••••••••••••••••••••••••••••••••••••••••
According to the problem given,
1,2,3 ,4, 5 , 6 , 7 are first seven natural numbers
Number of observations = n = 7 ( odd )
Therefore,
Median = [ ( n + 1 ) / 2 ] th observation
= [( 7 + 1 ) / 2 ] th observation
= 4th observation
= 4
Required median = 4
I hope this helps you.
