Now that you've started to build an advanced assessment, you may want to add a dot plot or line plot question.

In a Dot Plot or Line Plot question, students can create or modify dot plots or line plots. The dot/line plot can be pre-populated with data if needed.

Build the Question

If you are creating a new item, select the + Create button on the assessment builder, title the item, then select the Add New plus sign to add a question.

If you are adding to an existing item, simply select the Add New plus sign (as shown above) to add a question to the item.

Next, select the Charts category from the options on the left, then select Dot Plot or Line Plot

The only difference between the two is that the Dot Plot uses dots by default, while the Line Plot uses x's by default. The building methods are identical.

Step 1: Compose Question

  • Compose question: Type question prompt into this field.

You have many formatting options from the Rich Text toolbar, including changing the font size, adding tables, using math symbols, adding multimedia, and more! Click here for more information on the different functions of the Rich Text toolbar.

Step 2: Chart Settings

  • Add a Chart name, x and y-axis labels, and the maximum value for the y-axis

  • Add "points": the "points" are what will be on the x-axis. These are NOT the answers; this is the data that will be on the chart when the student arrives at the question.

    • Label: the "name" of the point. In the example below, the label on Point 1 is "1".

    • Value: The number of dots/lines that will be place on that point (the students will see these dots when they get to the question). In the example below, the value on Point 1 is 5, which means there are 5 dots with Point 1. If you don't want there to be any dots/lines with that point, make sure to have a value of 0.

    • Interactive: If you want the student to be able to manipulate the number of dots/lines for that point as part of the question, make sure to keep the Interactive checkbox activated.

  • If you need to remove a point, select the trash can icon.

  • If you need to add a point, select the blue +ADD button at the bottom of the list of points.

❗ To Change from a Dot Plot to a Line Plot (or Vice Versa)

  • In the More Options menu, navigate to the Layout section and change the Chart Type.

Dot Plot

Line Plot

➡️ Do you want students to build the dot plot from scratch?

  • Use the settings shown below in the Layout section. Try different options by checking/unchecking the box and going to Preview mode (upper-right corner) to see how the graph changes. For example, if you enable "Add point" that will let students add an additional component to the x-axis.

Set Correct Answers and Scoring

  • Step 1: Enter a point value in the Point(s) box. The default is 1.

  • Step 2: Plot correct response(s) on the chart. Select the bottom of the chart and drag the pointer up and down to establish the number of dots/lines.

❗ Only Exact Match (all-or-nothing) scoring is available with dot plots and line plots.

Student Preview

It's highly recommended to Preview the question as you are building it. This displays the question as the students will see it and you can plot the dots/lines to verify that the answers and scoring work as expected.

  • Step 1: Select the Preview button to go into Preview mode.

  • Step 2: Answer the question with the correct answers, including alternates.

    • Selecting Show Answers will present the correct answers.

  • Step 3: Verify that the auto-score correctly calculates the point value.

Here is a short clip of this question type from the student's perspective.

Optional Settings

Under the More options section you can set scoring type, formatting settings, and a number of other parameters for your question.

➡️ Scoring

  • Unscored/Practice usage: Removes all scoring from the question

  • Check answer button & Check answer attempts: Find more information here!

  • Scoring type: Only Exact Match is allowed for Bar Charts.

  • Enable auto scoring - You can choose to disable auto-scoring and score the question manually.

  • Penalty point(s): Students will lose points for incorrect answers (default is 0)

  • Minimum score if attempted: Students will receive points as long as the question has been attempted (if the question is left blank or is unanswered, the student will not earn those points)

➡️ Layout

  • Chart Type: you can change your chart from a Dot Plot to a Line Plot here.

  • Snap to Grid: defines how the data point is placed on the nearest grid line when the student is moving the data point (not used often).

  • Threshold: you can set a threshold: distance a point can be from the valid score and still be marked as correct.

  • Font Size: Choose from small, normal, large, extra large, or huge

  • The other settings, such as "Add Point" and "Delete Point" can be used if you want the students to add points to the chart and interact with them. When Add Point is enabled, students will see an Add Data button in the upper-right corner of the graph, indicating that they can add their own components.
