Hi!

The fifth option is correct!

As taught in the video lecture 3.5, one can clearly see about how ranks are calculated.

The simple formula :

Rank = percentile ( n-1 )+1

The evaluated answer is 12.9. Therefore the rank is 12. Henceforth, the data of people moves in ascending order, and it clearly shows that the person is the 7th tallest in the group.

Please review it.

If the rank is not a whole number, isn't it rounded to the next number. So, isn't rank 13?

In any case, the team has replied to a few other threads everyone will be provided with marks for this question since there is another issue.

I am not sure.

If you may refer to the Lecture -3.5, you'll observe that ma'am has clearly told about this ranking procedure. She mentions about separating the integer from the decimal part and then the integer part is referred as rank.

Hi,

Rank method is used by google sheets. You are not supposed to use that method.

Thanks,
