Abstract

The present data collection and analysis aid is for collecting quantitative data in different categories and tabulating the results. It features counting, time sampling, and item sampling data collection techniques. It is comprised of a dedicated hardware device or software running on a programmable computer. In either embodiment, category name displays are provided for identifying the categories. Count buttons are provided for entering counts in the categories. Count displays are provided for displaying the cumulative category counts. In response to each press of a count button, the aid is arranged to increase a corresponding category count by one, and to increase a total count for all categories by one. The percentage of each category count relative to the total count is also displayed. The counts and percentages are updated on the displays with each press of the count buttons. A correction button is provided for reversing the count inputs in case of error. For time and item sampling studies, the aid is arranged to indicate the required sample size based on parameters entered by the user to give the desired accuracy of the results. For time sampling, it is also arranged to periodically alert the user with a signal as to when to make an observation and enter a count. The entered data and analysis results are saved in a non-volatile storage device during shutdown and restored at startup. A plurality of studies may be stored and conducted simultaneously.
