Hi,

I keep getting 0 points for exercise 6, even though the vulnerability score distribution seems to exactly match the expected output. I don’t know how I can review this.

Here are the error messages:

Failed test case: vulnerability_score does not match the expected values. Make sure you used the correct formula to calculate the vulnerability score.

Failed test case: You seem to have the wrong values in the column "vulnerability_score"but they are likely due to errors in the vulnerability_score variable.

I had an error in earlier submissions. Maybe the grader is confused. :slightly_smiling_face:

Thank you!

Hi. Aside from the graph. Did you also get the same output in the next unit test? (top 5 counties by vulnerability score)

Hi Chris, yes. I got 10/10 in all other exercises including Ex.7 and the outputs match.

I just resubmitted the same notebook and I still get the same results plus an additional " Grader Error: Grader feedback not found" for exercise 1 (which I did not receive when submitting yesterday). Thank you!
