Sci vs Hypothesis Test

一、Basic Description 1、This software is mainly used in the digital experiment of primary and middle schools, including physical, chemical and biological experiments. 2、To work properly, the software needs to be used with sensors and bluetooth transmitter modules (sensors are connected to bluetooth launch modules). The sensor data is sent to the receiving end of the iPad or iPhone via a connected bluetooth module. 3、The software operates on portable mobile devices such as iphone or ipad, which has bluetooth low power consumption of BLE 4.0. 4、The overall design of this software adopts the Qt5.12.0 technical framework and Objective-C mixing method. 二、Use Instructions 1、Start the App software,scan the QR code on the back of the wireless transmitter module, and establish the connection between the mobile terminal and the module. 2、There are three kinds of software in App: general, special, and data upload software. • General software The general software has a "one-to-several" function, which supports four-channel parallel data logging and data recording, calculating, and graph analysis, without shifting the software interface. • The special software The special software is a software package composed of multiple independent software interfaces. Each independent software interface corresponds to a scientific experiment or inquiry project. According to project requirements, special software presets the corresponding operation steps and sequence. The current list of specific items for specific software is as follows: • Data Upload The data stored in the module can be uploaded to the mobile terminal by the data upload software. For easy control, it is recommended that the software be installed on the device with a screen of 4.7 inches and above. Please ensure that the operating system version is iOS 11.0 or above.

This app provides the ability to perform Type I Error hypothesis testing. The null hypothesis and sample size can be specified. Depending on the selected mode, the alpha error or the acceptance or rejection range can be calculated. The different modes offer the possibility of performing right-sided, left-sided or bilateral tests. For this purpose, k1 and/or k2 can be specified for mode I or II. Various modifications can be made to calculate the acceptance and rejection ranges. It is important to note whether X should be greater than/equal to or less than/equal to k. P(X)≤ α is always assumed. The solution is shown step by step. All calculations are saved in history. The final solution can be shared. [ Contents ] - 2 modes to calculate alpha error with right, left or bilateral tests - 4 modes for calculating acceptance and rejection range depending on α - Results are calculated and displayed in detail - History to save input - detailed solution - Natural numbers and decimal numbers are supported depending on the variable - no ads! [ Use ] - There are fields for entering values using a special keyboard - Click on the checkmark button at the bottom right to start the calculation - If values are missing, the corresponding field is highlighted in yellow - If the values are incorrect, the affected field is highlighted in red - a short message explains why a value is incorrect - The entries in the history can be deleted or sorted - When you select an entry in the history, it is automatically loaded for calculation - All history can be deleted at the touch of a button - Solutions can be shared
