INTMAN

Interval Manager for Windows and PocketPC

INTMAN is a software system for collection and analysis of fixed time interval observation data. The program collects data by presenting a screen with selections from up to 22 categories. The user observes the setting of interest for an “observe” period and then select applicable items from the available list for each category during a “record” period. The observe period, the record period and the codes to select from are customizable by the user. Observations can be done using a PocketPC or with ProcoderDV using digital media files. Data is analyzed using the INTMAN for Windows analysis program. Analyses can be done on single files or lists of files. Output is formatted into either a printable report or a comma separated text file for use with statistical or spreadsheet programs.

Available Analyses

Code frequencies - Frequencies and percentages of intervals re calculated from the observation files. The resulting output can be sent directly to spreadsheet or statistical programs for further analysis. Results can also be pooled across sessions.

Inter-observer agreement – The observation data can be compared within categories to determine the extent to which two observers agree on the observation session. A Kappa agreement table and Cohen’s Kappa statistics are provided as the results of the analysis for each code category.

Conditional Probabilities – The influence of code categories on each other can be assessed using condition probabilities.
