Now that you've started to build an advanced assessment, you may want to add a histogram question.

In a Histogram question, students can create or modify histograms. The histogram 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 Histogram

## 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.

## ➡️ Y-Axis Information:

• The number in the Max Y Value field will be divided by 10; those become the increments for the y-axis.

• There will always be 10 units on the y-axis (you are not able to add or remove units).

• Snap to Grid: If you need students to graph a number in between two units, use the Snap to Grid option. See the example below.

## ➡️ X-Axis Information

• 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 "January".

• Value: The starting height of the bar for that point. In the example below, the value on Point 1 is 0.

• Interactive: If you want the student to be able to manipulate the height of the bar for that point, 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.

# 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 height of each bar.

❗ Only Exact Match (all-or-nothing) scoring is available with histograms.

# 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 bars 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.

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

# 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

• 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 Bar Chart to other chart types.

• Snap to Grid: defines how the bar is placed on the nearest grid line when the student is moving the data point.

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

• Grid Lines: You can choose which gridlines the students will see (horizontal, vertical, neither, both).

• 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.
