# Question Analytics

Below is a list of all available Learning Analytics-data for each question in a test. To filter on a test use the Test-filter at the top.

### Order

The position of the question in this test.

### Exposed

The number of students, among those who submitted this test, who opened the question. Equals the sum of "Attempted" and "Omitted".

### Attempted

The number of students who answered the question.

### Avg. time

The average number of seconds spent on the question among the students who have seen the question.

### Omitted

The number of students who opened the question without answering it.

### Not exposed

The number of students who did not open the question.

### Correct

The number of students who answered the question correctly.

### Average score

The average score on the question among the students who submitted this test.

### Max score

The maximum score on the question.

### P-value

The P-value is the normalized average score on a question. This means that the maximum value of the P-value is 1, which happens if all the candidates answer the question correclty. It is worth noticing that the P-value can differ from the average score, even if the question has a maximum score of 1, because the P-value only takes into account the number of candidates that were epxosed to the question.

**Note**: If you use advanced scoring rules with negative scores, it may be difficult to interpret this value.

### Correlation

A number between -1 and 1. The correlation is the extent to which the question score correlates to the total score. Negative or very low positive values may indicate that the question does not discriminate (differ) well between students of high and low ability. See here for additional documentation: http://https://en.wikipedia.org/wiki/Point-biserial_correlation_coefficient.

**Note**: If you use advanced scoring rules with negative scores, it may be difficult to interpret this value.
