So you want to know how to make a slider scale work for your survey? We’ve got you covered.

In the following article, you will learn about

What’s a sliding scale?

To answer this question, let’s first understand what goes into a slider scale.

As an example, press one of the volume buttons on your keyboard. You will get something that looks like this.

This is a typical example of a slider scale.

A slider scale lets you view, adjust and select a value from the range displayed on the bar. Both ends of the bar can have icons, numbers, or labels to represent the opposite ends of the scale.

Slider scales are a standard UI control in most apps, and they function equally well in the offline world. Some common examples where we can see a slider UI in action include the climate controls in a car, the volume button on your phone, or the brightness adjuster feature on touchscreens.

Slider scale question in online surveys

Slider scale questions let you choose an answer value on a scale by dragging the button. This single-swipe action is easier than typing; it’s why sliding scales are a frequently recurring feature.

A slider scale is also a viable alternative to the limitations of a multiple-choice question, or a Likert scale question type, because it can include a broader range of answers.

How do you make a slider scale?

Here’s how you make a slider scale for your online survey using SurveySparrow.

Slider scale question example:

#1. Start a survey.

PS: If you’re new to the platform, you can try all of our features absolutely free for fourteen days. Sign up below.

#2. Select Slider from the list of question types.

#3. Choose the type of Slider from the dropdown menu. For our example, we’ll go with the Line Slider.

#4. Select a range in which your respondent’s input can be placed. In our example, we’ll go with the values 0-5.

For languages displayed left-to-right, like English, the smallest value for the range appears on the left, and the largest value appears on the right. But for right-to-left languages like Arabic, it’s the opposite.

#5. Toggle the Show Value switch to display your values on the slider. You can also toggle the Set Start Positions button to provide an initial default setting for the slider button.

In this example, we set the start position closer to the largest value of 5 to nudge the reader towards a favorable rating.

#6. You can make your sliding scale more precise by adding segments. Click the Segments button to select the number of divisions shown on the scale. We will choose 5.

#7. You can restrict it to a pre-defined decimal for a deeper level of precision. In our example, we chose 1, so the value will be increased in steps of 0.1.

Ta-da!

Types of slider scales

Single slider scales

Single slider scales allow you to select a single value.

Dual slider scales

A dual slider scale helps you select a range of values from the scale.

Continuous slider scales

A continuous slider scale lets you select a single value from a range of estimated values. Unlike other types, this slider scale is more exploratory because its purpose is to help the user compare different values quickly.

Continuous slider scales are frequently used to help a user filter by price range, like in Airbnb.

Discrete slider scales

Discrete sliding scales allow you to choose pre-defined values marked along the scale.

Example of a discrete slider UI in an alarm app. Sliding the button across hours and minutes helps set the alarm.

Graphic slider scales

Graphic slider scales frame the slider within a graphic that changes as you adjust the scale. This type provides a more appealing way for respondents to answer the survey.

SurveySparrow has four different graphic sliding scales for you to choose from:

#1. Thermometer: This sliding scale is a graphical slider in the form of a thermometer.

#2. Gauge Meter: This slider controls a rating scale displayed as a fuel gauge.

#3. Traffic Light: This is a 3-point sliding scale represented as a traffic light.

#4. Smiley: This is a 5-point slider scale with the points represented as smileys.

What are the benefits of a slider scale?

A broader range of answers

If someone asked me to rate chocolate ice cream on a scale of 1 to 10, I would answer an eight or a nine, depending on my mood. But what if my answer was closer to a 9 than an 8? Like, an 8.5 out of 10?

This is one of a slider scale’s most powerful advantages. Depending on how you set it up, it allows you to capture a broader range of answers compared to a standard rating scale or a Likert scale.

More precise answers

Slider scale questions enable respondents to indicate their choices with more accuracy.

A person’s actual response can often fall between the pre-set choices. It’s possible to capture this in text or multi-choice questions with the ‘Other’ option. But in rating scale questions, the format doesn’t allow for an ‘Other.’ A slider scale question is a good workaround for this.

Interactive format

In real life, buttons respond to our touch and provide instant visual confirmation of our choice. In surveys, a few question types check these boxes. One of them is the slider scale.

Visual feedback works because it appeals to the user’s natural desire for acknowledgement.

By allowing respondents to manipulate them like a physical switch, sliding scale questions increase their involvement, and make the survey a more pleasing experience.

What are the disadvantages of using a slider scale?

Limited application in surveys

Due to their interactive format, you can only use slider scale questions in mobile or online surveys.

However, the SurveySparrow Offline Survey App offers a “Record Audio” question type. This is an excellent workaround for the slider scale if you plan to do an offline survey. Using this question type, you can enable respondents to give their rating and record additional audio for up to a couple of minutes.

Tricky with touchscreens

How obsessed are we with our phones? Well, according to a report by Reviews.org:

  • 64% of Americans use their phone on the toilet.
  • 43% use or look at their phone while on a date
  • 35% use their phone while driving

These don’t cover the times we look at our phone on a commute, while waiting, during meetings, while we’re cooking or when we’re bored.

This data made us realize that people often check their phone with one hand while doing activities with the other. This means that, in practice, sliders can be tricky to manipulate on a touchscreen, because you need to tap and drag the button to the exact spot.

Accessibility issues

A slider scale is an even tougher task for respondents who have issues with their motor skills, or are physically/ visually challenged.

As a workaround, SurveySparrow’s Voice Transcription feature lets respondents record their answers to open-ended questions. You can use this feature to let them include a rating as well!

Wrapping Up

Now you know how to make the best use of your slider scale, including some workarounds for when a sliding scale question might not be the best choice. Time to put these tips into action!
