Answer:
median=2
Step-by-step explanation:
first, arranging the data is ascending order,
0,0,2,2,4,4,4
n(no. of observations)=7
then, applying the formula for odd no. of observations,
(n+1/2)th term
(7+1/2)th
(8/2)th
4th term is the median, which is 2.
samritisimmi:
yes its ryt ....but this is not the way.... hme median nikalna hai formula lga k i.e. l +{(n/2-cumulative frequency/frequency)}×i
i jst confuse that which cummulative frequncy should be taken? ....coz we have 2 same CFs
what's cumulative frequency? i solved the question this way because we were taught this way...maybe we'll do cumulative frequency in the coming classes...
