[Intro to R](http://openintrostat.github.io/oilabs-tidy/01_intro_to_r/intro_to_r.html)\n2. [Intro to data](http://openintrostat.github.io/oilabs-tidy/02_intro_to_data/intro_to_data.html)\n4. [Probability](http://openintrostat.github.io/oilabs-tidy/03_probability/probability.html)\n3. [Normal distribution](http://openintrostat.github.io/oilabs-tidy/04_normal_distribution/normal_distribution.html)\n5. Foundations of inference  \n  a. [Sampling distributions](https://openintro.shinyapps.io/sampling_distributions/)  \n  b. [Confidence intervals](https://openintro.shinyapps.io/confidence_intervals/)\n6. [Inference for categorical data](https://openintro.shinyapps.io/inf_for_categorical_data/)\n7. [Inference for numerical data](http://openintrostat.github.io/oilabs-tidy/07_inf_for_numerical_data/inf_for_numerical_data.html)\n8. [Simple linear regression](http://openintrostat.github.io/oilabs-tidy/08_simple_regression/simple_regression.html)\n9. [Multiple linear regression](http://openintrostat.github.io/oilabs-tidy/09_multiple_regression/multiple_regression.html)\n\n## Source code for labs\n\nWe currently support our source files in the RMarkdown (.Rmd) format, which can be output into html format (though output to pdf is also possible).\nThe source files are processed using the [knitr](http://yihui.name/knitr/) package in R, and are easiest to use in [RStudio](https://www.rstudio.com/products/rstudio/download/).\n\n## Feedback / collaboration\n\nYour feedback is most welcomed! If you have suggestions for minor updates (fixing typos, etc.) please do not hesitate to issue a pull request.\nIf you have ideas for major revamp of a lab (replacing outdated code with modern version, overhaul in  pedagogy, etc.) please create an issue so to start the conversation.\n\nIt is our hope that these materials are useful for instructors and students of  statistics.\nIf you end up developing some interesting variants of these labs or  creating new ones, please let us know!\n\n## Code of Conduct\n\nPlease note that the oilabs-tidy project is released with a Contributor Code of Conduct.\nBy contributing to this project, you agree to abide by its terms.\n\n* * *\n\n\u003ca rel=\"license\" href=\"http://creativecommons.org/licenses/by-sa/4.0/\"\u003e\u003cimg alt=\"Creative Commons License\" style=\"border-width:0\" src=\"https://i.creativecommons.org/l/by-sa/4.0/88x31.png\" /\u003e\u003c/a\u003e\u003cbr /\u003eThis work is licensed under a \u003ca rel=\"license\" href=\"http://creativecommons.org/licenses/by-sa/4.0/\"\u003eCreative Commons Attribution-ShareAlike 4.0 International License\u003c/a\u003e.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopenintrostat%2Foilabs-tidy","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fopenintrostat%2Foilabs-tidy","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fopenintrostat%2Foilabs-tidy/lists"}
