I have a formula question in a quiz. The formula question gives the correct answer. When students take the quiz, it show whether they got the correct answer. The quiz appears to give them a point then they get the correct answer.
However, when I pull up quiz statistics, it shows all of the responses to formula questions as "ungraded." (Below is what it looks like.) Is there any way to get a frequency of correct vs incorrect?
Attempts: 15 out of 16
If the variance is 6.59, then the standard deviation is what?. (Enter your answer to two decimal places.)
