@EnjoyMath

Here n=7 Therefore, q3= 3(n+1)/4 th position q3= 3*8/4=3*2=6 th position Now we have to arrange the observations in ascending order..then we see that the observation at the 6th position is 62. Pls let me know if you have any questions...

For example if the term number is 2.5, then you take the mean of 2nd and 3rd terms ..that will be the q1 value.... Pls let me know if you have any questions...

Hello, it's a really interesting question!! I verified with couple of different data sets, 2 times of range is approximately 2.6 times of IQR....so probably it should be 3 times,pls let me know if you have any questions

@EnjoyMath

Do verify it with a couple of examples .....I got 2.6 that way.... You may be right...but if 2 x range = 2x IQR Then the 2 on both sides of equal sign will get cancelled and we get, Range= IQR, which is usually not the case....

Suppose we have marks of 100 students and n/4 th data is 20 ,then it means the first 25 percentile of students have got marks lesser than or equal to 20. It tells us how well the students of that grade have performed in comparison to another class. Suppose in another class, n/4 th data is 14, it means the first 25 percentile of students have got marks lesser than or equal to 14...so it gives us a measure of comparison...pls let me know if you have any questions...
