Thanks a lot mate…
A lot of aspirants like me are highly obliged to your efforts…
Discrete Data-Find Quartile Deviation:
for Q1=6.75 should we not take Q1=10+.75(20-10)=17.5
because these case is same if we write the data as 10, 10, …(6 times), 20, 20, 20, 30, 30, 40, 40, …(these 40 should be 15 times). and then the problem becomes as ungrouped data case.
