:ref:`Grades` and :ref:`Review_Answers`.
* Moved information about the student **Progress** page from the
*Checking Student Progress and Issuing Certificates* section to
:ref:`Grades`.
* Renamed the *Checking Student Progress and Issuing Certificates*
section to :ref:`Checking Student Progress and Issuing Certificates`.
* - 05/21/14

This setting specifies the number of times a student can try to answer
the problem. By default, a student has an unlimited number of attempts.
.. note:: Only questions that have a **Maximum Attempts** setting of 1 or higher are included on the Student Answer Distribution report that you can download during your course.
You can use the Student Answer Distribution report to review student responses
to assignments, which can then help you evaluate the structure and completeness
of your courseware and problem components.
As an example, you define a text input question in Studio to have a single
correct answer, "Warfarin". When you produce the Student Answer Distribution
report, you verify that this answer was in fact marked correct: there is a 1 in
the **Correct Answer** column for this **AnswerValue**.
.. image:: ../Images/SAD_Answer_Review.png
:alt: In Excel, 5 rows show 5 answer values, 4 of which show comprehension of the question, but only 1 answer is marked as correct
However, as you view the report you notice other student answers that you did
not set up to be marked as correct in Studio, but that you might (or might not)
also consider to be correct, such as "Warfarin or Coumadin". The **Correct
Answer** column shows that the other answers were marked incorrect (0), but for
future iterations of your course you may want to revise the question or update
the problem to evaluate additional variations of the answer as correct.
Many spreadsheet applications offer data visualization options, such as charts
or graphs. Charts can help make your students' common misconceptions easier to
identify.
.. image:: ../Images/SAD_Column_Chart.png
:alt: In Excel, AnswerValue and Count columns next to each other, values for 4 rows selected, and a column chart of the count for the 4 answers
In this example, the Student Answer Distribution report is open in Microsoft
Excel. To create a chart that shows how many of your students chose various
answers to a multiple choice question, you move the **AnswerValue** and
**Count** columns next to each other. After you click and drag to select the
report cells that contain the data you want to chart, you click the Charts
toolbar and then click the type of chart you want.
.. note:: Refer to the help for the spreadsheet application that you use for information on using these options. You may have to make changes to your spreadsheet, such as reordering columns. Save a copy of the file you originally downloaded as a backup before you begin.
You can adjust your course content based on common student mistakes. While most
students in this example selected the correct answer, the number of incorrect
answer(s) can guide future changes to the courseware.
You can view a chart of the score distribution for a specified problem.
.. note:: To view the score distribution for a problem, you need its unique identifier. You can display a histogram for problems that have the ``/problem/`` prefix in the unique identifier. See :ref:`find_URL`.

Students can check their progress by clicking **Progress** in the course
navigation bar. The student's progress through the graded part of the course
displays at the top of this page, above the subsection scores. Progress is
visualized as a chart with entries for all the assignments, total percentage
earned in the course so far, and percent needed for each grade cutoff. Here is
an example of a student's progress through edX101.

The student can see from this page that edX101 was graded as a Pass/Fail course
with a cutoff of 34% and that the grading rubric contained one assignment type,
called Learning Sequence, consisting of 11 assignments total. Furthermore, this
particular student has only submitted correct responses to two assignments, and
that her current total percent grade in the course is 6%. By hovering over each
progress bar, the student can get further statistics of how much each assignment
was counted as.

Student Answer Distribution
****************************************
For certain types of problems in your course, you can download a CSV file with data about the distribution of student answers. Student answer distribution data is included in the file for problems of these types:
* Checkboxes (``<choiceresponse>``)
* Dropdown (``<optionresponse>``)
* Multiple choice (``<multiplechoiceresponse>``)
* Numerical input (``<numericalresponse>``)
* Text input (``<stringresponse>``)
* Math expression input (``<formularesponse>``)
The file includes a row for each problem-answer combination selected by your students. For example, for a problem that has a total of five possible answers the file includes up to five rows, one for each answer selected by at least one student. For problems that use rerandomization (the **Randomization** setting in Studio), there is one row for each problem-variant-answer combination selected by your students.
The CSV file contains the following columns:
.. list-table::
:widths: 20 60
:header-rows: 1
* - Column
- Description
* - ModuleID
- The internal identifier for the Problem component.
* - PartID
- For a Problem component that contains multiple problems, the internal identifier for each individual problem. For a Problem component that contains a single problem, the internal identifier of that problem.
* - Correct Answer
- 0 if this **AnswerValue** is incorrect, or 1 if this **AnswerValue** is correct.
* - Count
- The number of times that students entered or selected this answer as their most recent submission for the problem or problem variant. For problems with the number of **Attempts** set to a value greater than 1, this means that each student contributes a maximum of 1 to this count, even if the same answer is provided in multiple attempts.
* - ValueID
- The internal identifier of the answer choice for checkboxes and multiple choice problems. Blank for dropdown, numerical input, text input, and math expression input problems.
* - AnswerValue
- The text label of the answer choice for checkboxes, dropdown, and multiple choice problems. The value entered by the student for numerical input, text input, and math expression input problems.
* - Variant
- For problems that use the **Randomization** setting in Studio, contains the unique identifier for a variant of the problem. Blank for problems that do not use the **Randomization** setting, or that use the **Never** option for this setting.
* - Problem Display Name
- The **Display Name** defined for the problem.
* - Question
- The label for accessibility that appears above the answer choices or the text entry field for the problem. In Studio's Simple Editor, this text is surrounded by two pairs of angle brackets (>>Question<<). Blank for questions that do not have an accessibility label defined.
Entries are sorted by the value in each column, starting with the ModuleID on the left and continuing through the columns to the right.
An automated process runs periodically on the edX servers to update the CSV file of student answer data. A link to the most recently updated version of the CSV file is available on the Instructor Dashboard.
To download the most recent file of student answer data:
#. View the live version of your course.
#. Click **Instructor**, then click **Data Download**.
#. At the bottom of the page, click the ``{course_id}_answer_distribution.csv`` file name. You may have to scroll down to find this file.
Answers to questions about the student answer distribution report follow.
**My course doesn't have a student answer distribution report. How can I generate it?**
Student answer distribution reports are generated automatically, and refreshed several times each day. The ``{course_id}_answer_distribution.csv`` file displays after all of the ``{course_id}_grade_report_{date}.csv`` files. Be sure to scroll to the end of the list of available reports.
**Why are some problems missing from this report? The ones that are missing do have the problem types listed under** :ref:`Review_Answers`.
This report includes only problems that at least one student has answered since early March 2014. For those problems, this report only includes activity that occurred after October 2013.
**Why don't I see an AnswerValue for some of my problems?**
For checkboxes and multiple choice problems, the answer choices actually selected by a student after early March 2014 display as described in the previous answer. Answer choices selected by at least one student after October 2013, but not selected since early March 2014, are included on the report but do not include an **AnswerValue**. The **ValueID** does display the internal identifiers, such as choice_1 and choice_2, for those answers.
**Why don't I see a Question for some of my problems?**
The value in the **Question** column is the accessibility label for the problem. For more information about how to set up labels for problems, see :ref:`Create Exercises`.
Also, for problems that use the **Randomization** setting in Studio, if a particular answer has not been selected since early March 2014, the **Question** is blank for that answer.
**My students are saying that they answered a question, but it isn't showing up in the report. How can that be?**
Only questions that have a **Maximum Attempts** setting of 1 or higher are included on the report.
**I made a correction to a problem after it was released. How can I tell which students tried to answer it before I made the change?**
Problem **Count** values reflect the entire problem history. If you change a problem after it is released, it may not be possible for you to determine which answers were given before and after you made the change.
**Why is the same answer showing up in two different rows when I view the report in a spreadsheet?**
Some spreadsheet applications can alter the data in the CSV report for display purposes. For example, for different student answers of "0.5" and ".5" Excel correctly includes the two different lines from the CSV, but displays the **AnswerValue** on both of them as "0.5". If you notice answers that appear to be the same on separate lines with separate counts, you can review the actual, unaltered data by opening the CSV file in a text editor.
**Why are there strange characters in the report when I view it in a spreadsheet?**
The CSV file is UTF-8 encoded, but not all spreadsheet applications interpret and render UTF-8 encoded characters correctly. For example, a student answer distribution report with answer values in French displays differently in Microsoft Excel for Mac than in OpenOffice Calc.
Answer Values in Microsoft Excel for Mac:
.. image:: ../Images/student_answer_excel.png
:alt: A spreadsheet that replaces accented French characters with underscores
Answer Values in OpenOffice Calc:
.. image:: ../Images/student_answer_calc.png
:alt: A spreadsheet that displays accented French characters correctly
If you notice characters that do not display as expected in a spreadsheet, try a different spreadsheet application such as LibreOffice or Apache OpenOffice to open the CSV file.
You can use the Student Answer Distribution report to review student responses to assignments, which can then help you evaluate the structure and completeness of your courseware and problem components.
As an example, you define a text input question in Studio to have a single correct answer, "Warfarin". When you produce the Student Answer Distribution report, you verify that this answer was in fact marked correct: there is a 1 in the **Correct Answer** column for this **AnswerValue**.
.. image:: ../Images/SAD_Answer_Review.png
:alt: In Excel, 5 rows show 5 answer values, 4 of which show comprehension of the question, but only 1 answer is marked as correct
However, as you view the report you notice other student answers that you did not set up to be marked as correct in Studio, but that you might (or might not) also consider to be correct, such as "Warfarin or Coumadin". The **Correct Answer** column shows that the other answers were marked incorrect (0), but for future iterations of your course you may want to revise the question or update the problem to evaluate additional variations of the answer as correct.
