I'm not sure what does the result mean? How come women/total ratio can be greater than 1?

Screen Link:

My Code:
select Major_category, sum(CAST(Women as Float)) / sum(CAST(Total as Float)) as SW
from recent_grads
group by Major_category
order by SW

What I expected to happen: SW column has decimal values ranging from 0 to 1

What actually happened: as you can see in the result table, some major category has a ratio greater than 1, and some has suspiciously low ratio such as 0.03

Other details: I was under the impression there’s no overlap the amount of people majoring in each major, thus, the sum of all women majoring in a Major_category divided by total amount of people majoring in a given Major_category should range between 0 to 1.

Please let me know what’s going on here? Thank you.

A couple weeks ago another student pointed this out as well: Error in Data Source? The Share of Women Is More than 100%

It did look sketchy so a ticket was created so the team could have a look at it. @dustindq do you know if there were any updates?

No updates just yet! It’s definitely on our list of things to fix, however, so thanks for your patience in the interim.

Hi @dustindq, the issue still exists.

Hey there! It’s going to take a bit of time to fix since we’re working on addressing other bugs as well — rest assured, it’s on our to-do list so thanks for hanging tight in the interim!
