What is Observed vs Expected? ✏️

The observed vs expected frequency is designed to help you identify patterns in your data by comparing the observed frequency of a segment across the overall data set with the expected frequency of a segment when looking at a specific part of the data.

Let's take a closer look...

Observed Frequency

The observed frequency shows the percentage of records that a particular segment matches when looking at a specific set of data (e.g. once you've applied a Dashboard Filter or have clicked into a specific query / theme to explore).

The particular segments you can filter by depends on what Fields your team has included in the overall data set during the initial setup stage.

Tip: Use the dropdown menu to choose a different field to segment by!

Expected Frequency

When drilling down into a saved query like "In Flight Entertainment" on the dashboard, the field segmentation chart will show an additional value, Expected Frequency.

The expected frequency, depicted by the small vertical line, shows you the percentage of records that a particular segment (like Cabin Flow) matches when looking at the overall data set (regardless of the query you've clicked into or what filters you have applied).

How is the expected frequency calculated? ✏️

To calculate the expected frequency, we look at the differences between the Expected Frequency and Observed Frequency to see if there are any discrepancies between the two.

In the example above, we can see that the Observed Frequency (the percent of Economy Class Passengers who are talking about In Flight Entertainment (the Query we're exploring) is 74.25% and the Expected Frequency (the total percent of Passengers who flew Economy across the entire data set) is 67.39%.

This means that more passengers who flew Economy Class are talking about the In Flight Entertainment than what we expected (meaning that this particular segment is over indexing when it comes to comparing the Segment with the Query).

Conversely we see the opposite with "Business Class" respondents!
