Pairwise Ranking Survey

Pairwise Ranking or Preference Ranking is a tool to set priorities between different options available. Pairwise Ranking is a tool that is used primarily to explore people’s perceptions, elicit criteria, and understand their choices and decision-making.

In Pairwise Ranking, each individual item is compared directly against the others so as to emerge with a ranking from highest (Most Prefered) to lowest (Least Prefered).The pairwise ranking survey process uses a machine optimized process to display two items at a time. The respondents have to pick one of the two items.

We are using a Machine learned ranking algorithm that computes the preferred order of respondents based on the input given by the respondents

Since the number of rankings is N!, In general, specifying a ranking requires N log N bits of information. This implies that at least this many pairwise comparisons are required.

It is a new feature provided under manage workforce tab.Here you can add a question with items for pairwise ranking of items. To add PathFinder go to:

• Login>> WorkForce>>Manage Workforce>>PathFinder
• Click on “Add New PathFinder”
• Here you can provide
• Name - This is to summarize what is contained in your question and options. Example: Adventure sports
• Question Example: What is your preferred Adventure Sports?
• Options - This will contain items/options to be given to users which will be then analyzed using pairwise ranking . Example: Paragliding, Scuba Diving, Bungee Jumping etc.

You can respond to the pairwise ranking survey on your WorkForce Pulse app. To respond to the survey go to:

• Login to Pulse app>> PathFinder
• Take the pairwise ranking survey
• View the rank you have given to the options

To view the dashboard of all the responses, go to:

• Login>> Manage Workforce>> PathFinder
• Take the pairwise ranking survey
• View the rank you have given to the options
• Click on “Analytics”

Average Rank : The answer choice with the largest average ranking is the most preferred choice.

The average ranking is calculated as follows, where:

w = weight of ranked position

x = response count for answer choice

x1w1 + x2w2 + x3w3 ... xnwn/Total

Weights are applied in reverse. In other words, the respondent's most preferred choice (which they rank as #1) has the largest weight, and their least preferred choice (which they rank in the last position) has a weight of 1. You can't change the default weights.

For example, if a Ranking question has 5 answer choices, weights are assigned as follows:

• The #1 choice has a weight of 5
• The #2 choice has a weight of 4
• The #3 choice has a weight of 3
• The #4 choice has a weight of 2
• The #4 choice has a weight of 1

Data Visualization is done using Word clouds (also known as text clouds or tag clouds) Option with higher weighted average implies it has better ranking hence that option will appear bigger and bolder in the word cloud.
