# Set Up a MaxDiff Question

> Add a Max diff question, set its items and items per screen, and add images to its items.

A Max diff question shows participants small sets of items. In every set, each participant picks the most and the least of an attribute you set, such as "important". Use it to find which items matter most.

## Add the question

1. In the study editor, click **Add Question**.
2. Click **Max diff**.
3. Type an attribute in the **Attribute** field, such as "important".
4. Type each item under **Options for Least \_\_\_ or Most \_\_\_**.
5. Click **Add option** to add more items.

* Each item needs unique, non-empty text.
* A Max diff question needs at least two items.
* It needs at least as many items as its items per screen value.

## Set items per screen

1. Open the **Items per screen** setting in the question menu.
2. Click **3 items per screen**, **4 items per screen**, or **5 items per screen**.

* The default is 4 items per screen.
* You cannot pick a size larger than the number of unique items.
* The editor shows **Display N sets**. Each item appears about three times across all sets.

> [!NOTE]
>
> After responses come in, you cannot change items per screen. The analysis needs every screen to show the same number of items.

## Add images to items

1. Open the image setting on the question. It reads **Add images to options** until you add an image.
2. Click **Text only**, **Image options with text**, or **Image options only**.
3. Upload an image to each item.

* **Image options only** hides the item text for participants. Each item still needs text in the editor.

## Settings that do not apply

* There is no **Order** setting. Participants see items in a random order.
* There is no **Follow-ups** setting. To ask why a participant chose an item, add a separate open-ended question after the Max diff question.
* Max diff questions cannot be in a screener block.

## What participants see

* Each set appears on its own screen.
* The left column reads **Least** and the right column reads **Most**, followed by your attribute.
* Participants pick one item in each column. Picking an item in one column removes it from the other.
* The **Next** button stays disabled until both columns have a pick.
