# Using Graphs

The graphing features in GradeQuick serve two major purposes: 1 they provide easily understood visual description of class performance; 2) they can help you decide where to set grade cutoff values for your grading scale to achieve the distribution you want.

The **Graph** menu offers you the choice of graphs for students, tests, subtotals or final averages. GradeQuick offers two basic graphing functions. One shows a student’s progress, and the other shows the distribution of student grades for a specific test or subtotal, or for the final average.

### Working with Graphs

To access the graph feature, select one of the graph types from the **Graph** menu. Once you are in the graph window, you can choose different graph types and styles. The graph window contains a toolbar to allow you to manipulate the current graph type if you prefer a different style. You can also print the current graph from the graph toolbar.

### Graph Toolbar

The toolbar icons are listed before as they appear from left to right.

## Student Progress Graphs

The student progress graphs give a clear visual picture of the trend in a student’s performance.

- Click
**Graph > Student**, and choose the student whose scores you want to graph from the scroll list at the left. - You can select whether to see the trend in
**Percent**or**Percentile**.- The
**Percent**option shows a graph of the student’s average score on each test through the marking period. - The
**Percentile**option would show the percentage of the class that placed below the student on each test.

- The
- You can choose to see a graph of all of the student’s work by selecting
**All Categories**from the sub-menu.- You may view a graph of the student’s work in only one category.

- You can also choose to plot the Class Mean as well by toggling the Graph Class Mean option.

Select the Type of Graph 3D Bar, 2D Bar, pie chart or Line Graph.

- To print the graph, click the
**Print**icon on the toolbar or click**File > Print.**

## Grade Distribution Graphs

Choose **Test or Subtotal** or **Final Averages** from the **Graph** menu.

- To see the distribution of grades based between students’ final semester and year averages, click
**Graph > Final Average**. - If semester subtotals are displayed on the spreadsheet instead of the year’s overall grade, the graph will show distribution for the displayed semester.
- If you want to see the distribution of a particular test or subtotal, select
**Tests or Subtotals.**In the dialog box a scroll box will display all of your tests so that you may select the test or subtotal to graph. - Subtotals must be displayed on the spreadsheet in order to be available for graphing.
- An arrow in the scroll box precedes the subtotal choices.
- After choosing which test, subtotal, or final average to graph, you must choose whether to group students by letter grades or raw scores.
- If you choose Group into
**Grades**, GradeQuick will graph the number of students that received each grade in the column being graphed. - If you choose
**Group into Equal Subdivisions**, GradeQuick will divide the range of possible grades into as many equal subdivisions as you choose, and graph the number of students whose score in the column being graphed fell into the range of scores for each subdivision.

To print the graph, click the **Print** icon on the toolbar or click **File > Print**.

## Choose Graph Type

There are five different types of graphs.

**3D bar**.**2D bar**. The 2D Bar chart displays the Y-axis value above each bar**Line graph**. A line graph plots the y-axis value of each item on the x-axis as a point, and connects each point with a line.**Pie chart.**A pie chart divides a circle up like a pie, drawing a slice for each grade or subdivision. The size of each slice represents the percentage of the class who scored within each grade or subdivision range. If no students fall into a category, that category will be missing from the chart. GradeQuick cannot draw a piece of no size. For example, if you group by grades and no students earned Fs, the chart will only show pie slices for grades A, B, C, and D. Likewise, if you ask for 10 subdivisions, but no students fall into the 0-10 range, or 10-20 range, only 8 pie slices will appear.**Distribution Function (cumulative)**. A cumulative distribution graph shows, for any grade or score, the number of students receiving that score or lower.
