About

Size test

Read full description

This app is designed to assess how quickly the user reacts to changes in the size of an object. Users can select one of the test modes: 'Increasing the object', 'Decreasing the object', 'Decreasing or increasing the object'. When the user observes a change in the size of an object, the user must break contact with the device screen. The recorded test time reflects the user's ability to perceive the change in object size. Once the test is completed, the results are tested for normality of distribution (Shapiro-Wilk test). If the values deviate from the law of normal distribution, the program analyzes the data sets, removes the worst value and adds an additional attempt. In the program settings you can select the number of attempts - from 10 to 30. The choice of the number of attempts depends on the performer's age and professional activity. In addition, in the program settings the user can save a backup copy of his measurements in JSON format anywhere (Save backup), add measurements from another device (Add backup), replace already saved measurements with new ones (Replace backup) or delete all data (Delete all data). This application is intended to be used by athletes and teachers in specialized educational institutions for scientific research.

About

Galileo Data Entry

Features
Read full description

This great App allows the social scientist to conduct surveys that all users of the app will see. The users fill out these surveys by reporting the differences (or distances) between a list of concepts. The user reports the distance of each concept to each other concept. This data creates a matrix of responses that can be reconstructed into a 3D map showing a 'conceptual space' using 'R' software, available for free download. This App can be also be used to collect any multidimensional scaling data such as that collected and mapped by SPSS, Statistics Package for the Social Sciences, an IBM product and a variety of other applications that are available for purchase. When the user is done filling out the survey, the user selects 'Exit and Send' and the data that was collected by the App is delivered to the social scientist as a list of pairs of concepts and the differences (or distances) between them. Any questions, contact the author on the support site! Need a custom version for your organization? Contact the author? This software can also be used to collect data for the Galileo System created by Rick Holmes and a variety of students over the years from Michigan State University, SUNY Albany and SUNY Buffalo including the author for Dr. Joseph Woelfel.
