About Art of Stat: Explore Data

This app includes statistical methods for:

- Analyzing One Categorical Variable

- Comparing Groups on a Categorical Variable

- Analyzing the Relationship Between Two Categorical Variables

- Analyzing One Quantitative Variable

- Comparing Groups on a Quantitative Variable

- Analyzing the Relationship Between Two Quantitative Variables (Linear Regression)

You can type in your own data or copy & paste data from the Excel spreadsheet app. Alternatively, upload your own CSV file (which any spreadsheet program can create) of your own data into the app and select the variables to analyze from its columns.

The app provides:

- Frequency tables and bar and pie charts for exploring one categorical variable.

- Contingency tables, conditional proportions and side-by-side or stacked bar charts for exploring a categorical variable across several groups or the association between two categorical variables.

- Mean, standard deviation and the 5-number summary together with histograms and boxplots to explore a quantitative variable.

- Side-by-side boxplots, stacked histograms or density plots for comparing a quantitative variable across several groups.

- Interactive scatterplots with regression lines to analyze the relationship between two quantitative variables. Correlation statistics and linear regression parameters and predictions. Plots of raw and studentized residuals.

The app comes with several example datasets preloaded, which you can directly open in the app to explore the app's various feature with a real dataset. You can also upload your own datasets to the phone by simply sending a csv file as an email attachment (or placing it in iCloud).
