Usually the median is defined by the middle number, so without any doubts I can say that due to the fact that half of population has zero effect the overall index is zero. Hope it is clear that the last ( D.The median debt is zero because more than half of credit card debts are zero.) option is the only correct answer whereas the others ones are wrong.
Ok so first u would add 3+1 which gives u 4 and then add 1/4 which should give u 4 1/4
Double facts the even and odd numbers for example 2×2=4
