I think there is something wrong with the analysis

Hi! I did not expect to write 2 posts a day, but I am a curious potato so I had to ask.

I noticed that some analysis of questions show the bar to fill all 5 squares, but the average people who get the score is really low, or the percentage of people who get this right is high.

Is this normal? Or are they in the middle of collecting data for more accuracy?

I got a question right that I thought to be hard, but when I saw the analytics I was very confused.

Below is what I mean 😊 Thanks in advance!
