I will not disclose here any answer as it is required!
But I was surprised to see my answer was wrong.
Why was I surprised? Because you know the number of all customers and you know how many have churned so to calculate the percentage of churned customers is easy. You can also work with filters in this case and come to the same result.
Are those customers with the status “Joined” not counting in the number of total customers?
Please help me to understand. Thank you!
Btw: I passed anyhow.
Hey @Zardoz!
Welcome to the forum 
I just checked the answer for this quiz, and your logic here is correct: What the grader expects is `[total clients who churned] / [ total clients in the dataset]`. This is indeed a simple calculation.
Maybe the issue here lies in the question: “Round to the nearest whole number."?
I revised the data, and you get a fraction. In this case, the nearest whole number is not the ‘integer’ part of the number, but the ‘next integer’.
Does that make sense?
The grader works well following the above. If you still have questions, please share them here, and I’ll do my best to help you.
Happy learning in 2026!

Hi @Donald7759, welcome to the forum
Let’s keep it in English, please, so everyone can understand
In this specific case, while it might be tempting to just use the integer part (truncating), this question specifically asks to round to the nearest whole number. That means standard rounding (e.g., 0.50 and above rounds up, below 0.50 rounds down). As a mentor/tester, I can confirm this approach will work with the grader here.
