Stats tester mini vs Izzy Statistics

### Features of this app ### 1. By using Stats tester mini, you can perform some statistics tests and obtain graphs by an easy operation. 2. Since one sample group (multiple data) is entered in one window, it is very easy to enter or edit the data. 3. Unlike other test apps, not only final conclusions such as p-values, but also intermediate results are shown. 4. Input data and test results can be recorded by sharing (mail, memo). There is no need to make notes on paper. 5. You can import data by copy/paste from apps such as Excel, Numbers, memo, etc. 6. Numerical input is very easy with the built-In ten-keyboard (phone and calculator layouts). 7. This app has been fully verified to work with the M1 Mac. The M1 Mac makes it easy to work with other apps (Numbers, Excel etc.). ## how to use ## Each test screen has [Help], [Example], [Graph], [Calc], [Clear] and [Share] Buttons. On the "How to use this app" screen, details such as its features and specifications are written. ### Statistic methods ### Below are the statistical methods in Stats tester mini. (The upgraded version "Stats tester plus" offers 18 more methods.) 1. Mean, SD, Skewness, Kurtosis, etc. 1) Arithmetic, Geometric and Harmonic means 2) Standard Deviation (2) 3) Standard Error of the mean (sem) 4) 95 and 99% Confidence interval (CI) 5) Sum 6) Sum of Square 7) Variance, Unbiased variance 8) Coefficient of variation (%CV) 9) Skewness (2) 10) Kurtosis (3) 11) Graph 2. Median, Range, Quartiles and Boxplot. 1) Median 2) Maximum 3) Minimum 4) 1st Quartile 5) 3rd Quartile 6) Quartile Deviation 7) Boxplot Graph 3. One-Sample t-Test (to Specified Mean) 1) Mean 2) Standard deviation (2) 3) Standard error of the mean (sem) 4) One-sample t-test --> p value 5) Confidence interval (CI) 6) Graph 4. Two-Sample t-Test (Student's and Welch's t-Tests) 1) Mean 2) Standard deviation (2) 3) Standard error of the mean (sem) 4) Student t-test --> p value 5) Welch's procedure --> p value 6) Graph 5.

The most complete statistical tool. With an intuitive and simple interface that will facilitate your statistical calculations wherever you are. It doesn't matter if you are a student or a professional, it is just as functional. Enter the numbers of a sample or a population separated by a space, select if the data belongs to a sample or a population, touch the calculate button and you will obtain the result of the following equations: - Ordered numbers - Total numbers - Arithmetic Mean - Median - Mode - Quartiles - Interquartile range - Range - Average deviation - Variance - Standard Deviation - Coefficient of Variation - Typical Values - Atypical Values - Extreme Atypical Values You can also create and get the histogram properties of the data: - Histogram - Lowest and highest data - Distribution Range - Total numbers - Classes Number - Classes Range - Classes Besides you can: - Save the data for future use and not have to enter it every time you need it - Update the data in case you need to add, modify or delete any - Delete the data when you think you no longer need it Do not forget to leave your comment and rating, as well as share the app with your friends.
