Art of Stat: Concepts vs Izzy Statistics Usage & Stats
Explore the Central Limit Theorem, learn about the correlation coefficient and linear regression, and visualize the coverage probability of confidence intervals or Type I & II Errors in hypothesis testing.
Build understanding by experiencing these important concepts step-by-step. For students and teachers of statistics.
The Art of Stat: Concepts app provides access to the following modules:
- Central Limit Theorem for Means
- Central Limit Theorem for Proportions
- Explore Correlation
- Explore Linear Regression
- Explore Coverage
- Errors & Power
CLT: Select from several real population distributions (left and right-skewed or fairly symmetric) and simulate taking a sample from the population.
Visualize how the sampling distribution builds, step-by-step. Explore the effect on the sampling distribution as you increase the sample size. Overlay the normal distribution.
Compare the sampling distribution of the mean to the population distribution, both visually and in terms of key statistics.
Explore Correlation/Linear Regression: Create (and delete) points in a scatterplot by tabbing on the screen. Show the regression line or residuals. Simulate scatterplots and guess the correlation coefficient.
Coverage and Errors: Explore what 95% coverage for a confidence interval for a population mean or proportion implies.
See the Type I and Type II error and explore how they depend on the sample size and the true parameter value. Find and visualize the power of a hypothesis test.

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
