Weak Points: Somewhat expensive
With the Data Explorer app, users can quickly perform an impressive array of statistical analyses from their mobile devices. Within the app, users organize their data into workspaces, which can be populated manually from within the app or with data imported from CSV, .txt, or Excel files. An example workspace is included for users to familiarize themselves with the app’s functionalities. Within a workspace, users can view summary statistics (such as mean and median values) for their data on the variables page, and they can access the statistical tests from the analysis page. Seven types of analyses are available: two-way table of frequencies, bivariate analysis, hypothesis testing of means, hypothesis test of proportions, linear regression, logistic regression, and one-way ANOVA. The statistical tests are accompanied by a very nice user interface and text descriptions that help to interpret the results.
