Izzy Statistics vs Art of Stat: Resampling Usage & Stats
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

Modern statistical calculator for teachers and students of statistics.
The Art of Stat: Resampling app lets you find bootstrap confidence intervals and permutation P-values. The app illustrates the procedures interactively so you can understand how they work. Several example datasets are preloaded for you to explore, but you can also enter your own data or import a CSV file.
The following resampling methods are implemented:
- Bootstrap Confidence Interval for a population mean, median, or standard deviation.
- Bootstrap Confidence Interval for a population proportion or the population odds.
- Bootstrap Confidence Interval for a population correlation (Pearson and Spearman) or the population slope of a regression model.
- Bootstrap Confidence Interval for the difference of two population means or medians.
- Permutation Test for a population mean or median.
- Permutation Test for the difference of two population means or medians.
And coming soon:
- Permutation Test for the independence of two categorical variables (Permutation Chi-Squared Test)
Easily find the bootstrap confidence interval based on the percentile and other methods. For inference about the population mean, compare results to traditional methods based on the Student-t distribution.
Each procedure has three screens:
1) Enter Data, where you provide the data and obtain descriptive statistics and corresponding graphs (Histogram, Boxplot, Bar Chart).
2) Simulate Distribution, where you generate the sampling distribution (or the null distribution for permutation tests) of a chosen statistic.
3) Confidence Interval/Permutation P-value, where you use the generated distribution to obtain the confidence interval or the permutation P-value, along with lots of supporting information and comparison to classical, central-limit-based inference.
The app also has a Data Editor spreadsheet for you to enter or edit (and save) your own data.
