Code Frequencies

The Code Frequencies tool allows you to see how much of each document is covered by each code. Codes make up the rows of the table, and documents make up the columns. Each cell shows the percentage of that document that is coded with that code.

Where Codes in Documents counts how many times a code is applied, Code Frequencies measures how much of a document it covers. A single long passage and ten short ones can count very differently, but cover the same amount.

To open Code Frequencies:

1. Click the Analyse button in the toolbar.

2. Choose Code Frequencies.

The tool contains:

• The Document Selector
• The Group By function

Adding codes

To add codes to the table:

1. Drag the codes from the Code Browser into the Frequency Grid box.

2. Each code appears as a row in the table, and a chart appears beneath it.

3. To remove a code, click the x beside its name.

Reading the results

The frequency table, grouped by the Student type tag category.

Each cell shows the percentage of that document covered by that code. Where selections coded with the same code overlap, the overlapping part is only counted once.

How the percentage is calculated depends on the type of document:

Document type	Percentage of
Text	The characters in the document
Audio and video	The length of the recording
PDF (text selections)	The text in the PDF
PDF (box selections)	The box selections in the PDF
Image	The box selections in the image
Survey	The text of the open-ended answers

INFO

Images do not have a "length" in the way that text or recordings do, so Magnolia measures them by their selections instead. If an image has four box selections and one of them is coded with a code, that code covers 25% of the image. You can see these rules at any time by clicking the ⓘ button above the table.

Clicking the ⓘ button explains how the percentages are calculated.

The chart beneath the table shows the same results as a bar chart. Each code has a group of bars, with one bar for each document or group.
