How to use Comparison

The Comparison tool displays the frequencies of the base and sub-themes Thematic has identified in your data set using bar graphs.

Feature walkthrough

The base themes are shown in the left bar graph and organized by the greatest frequency. The right bar graph shows the sub-themes of the selected base theme, which will be pointed to by the grey arrow. You can select a base or sub-theme by clicking on it. 

Any applied filters and the total number of comments are displayed at the bottom of both graphs and will update as you filter your data. You can hover your mouse over a base or sub-theme to see it's percentage, number of comments and data filters. 

Use the options menu to sort the base themes by highest or lowest frequency first. This always sorts with the blue filter theme frequency. Applying an orange filter enables you to sort by comparison difference.

The selected theme will be named in the right section and have its related comments displayed. 25 comments are shown by default, which you can scroll up and down to view. The More button at the bottom loads another 25 comments at the bottom.

If you have an  Admin or Analyst account you can download all comments related to the selected theme as a .csv file by clicking the download button. You will be prompted to choose the file's save destination on your computer. This .csv file will contain additional information, like the themes Thematic has identified in each comment and sentiment score.

Filters

Comparison is compatible with any filters you can apply. Applying an orange filter will add an adjacent set of orange bars to the graph to represent the second filtered set of data.

Adding an orange filter allows you to select comparison difference in the options, which sorts the base themes by the greatest difference in frequency in the two filtered sets of data. Difference is selected by default once you apply an orange filter.

Mouse over each theme to see additional information if the difference in theme frequency is  statistically significant. Filtering your data will load two sets of related comments, select which one to view by clicking on it above the displayed data

if you have an  Admin or Analyst account the download related comments drop down will add an option to download either set of filtered data individually.
