Codes and Cases in Selected Dynamic Sets: all the codes and cases included in selected dynamic sets.Cases Assigned to Selected Classifications: all the cases with selected case classifications.Codes and Cases in Selected Static Sets: all the codes and cases included in selected static sets.Selected Codes: coding to selected codes and/or cases in the selected files.All Codes: coding to all codes and cases in the selected files.Use the At field to select the codes and/or cases you want to compare coding for:.If you include more than 1 user in a group, any coding carried out by any of the users in the group counts towards the comparison. For User Group A and User Group B, select the users whose coding you want to compare (recommended to compare individual coders).The Coding Comparison Query dialog box opens. On the Explore tab, in the Queries menu select Coding Comparison.Export query results Run a coding comparison You cannot save query results in NVivo, however you can export them to other applications (e.g. Queries are saved under Queries / Query Criteria in the Navigation View. You can save query configuration settings to run the same query at a later time, when more coding has been done. Text coding uses text characters as the unit of comparison. PDFs can have both region (pixel range) and text coding.
#NVIVO CODING CODE#
If you code text in the description/notes of a picture file all the pixels in the picture are treated as having been coded.So, for example, two coders who code different sentences in a row will be reported as in agreement for the entire row timespan. If you code transcript text in an audio or video file, the timespan of the entire transcript row is treated as having been coded.All coding in picture, audio and video files is region coding, using pixel ranges (rectangles defined by their top-left and bottom-right corners) or timespans.All coding in documents, datasets, externals, memos, codes and cases is text coding.These are treated separately, producing separate results: Coders are identified by their NVivo user profiles User profiles.īoth text coding and region coding can be compared. If comparing groups, content is taken to be coded if at least one member of a group coded it. It is possible to compare coding between groups of users, however, standardly, comparisons are made between individual coders. You can also select groups of codes or files by identifying folders, static sets or classifications they belong to. You can select specific codes (or relationships or sentiments) or cases for comparison, in selected data files, datasets, externals and/or memos. Cohen's kappa coefficient: a statistical measure that takes into account the amount of agreement expected by chance-expressed as a decimal in the range –1 to 1 (where values ≤ 0 indicate no agreement, and 1 indicates perfect agreement).Percentage agreement: the number of content units on which coders agree (to code or not to code), divided by the total number of units-reported as a percentage.Agreement is measured by two statistical methods: The coding comparison query compares coding by two users to measure 'inter-rater reliability'-the degree of coding agreement between them.
