Inference for categorical data LAB 6
Inference for categorical data In August of 2012, news outlets ranging from the Washington Post to the Huffington Post ran a story about the rise of atheism in America. The source for the story was a poll that asked people, “Irrespective of whether you attend a place of worship or not, would you say you are a religious person, not a religious person or a convinced atheist?” This type of question, which asks people to classify themselves in one way or another, is common in polling and generates categorical data. In this lab we take a look at the atheism survey and explore what’s at play when making inference about population proportions using categorical data.

Project 3 Data Science Thought Leadership (Final )
In this project, we breakdown how we built a database of influential people who are leading the charge in what the Harvard Business Review suggested to be the sexiest job field of the 21st century, that is Data Science. Because their skills and knowledge lead them to a successful data science career, with our database, we conducted a few data analysis to further discuss the many different paths that can lead you too to a lucrative, rewarding career as a data scientist.

In this project, you’re given a text file with chess tournament results where the information has some structure. Your job is to create an R Markdown file that generates a .CSV file (that could for example be imported into a SQL database) with the following information for all of the players: Player’s Name, Player’s State, Total Number of Points, Player’s Pre-Rating, and Average Pre Chess Rating of Opponents. Example For the first player, the information would be: Gary Hua, ON, 6.0, 1794, 1605 Contributors: Santosh Cheruku Samantha Deokinanan Rajwant Mishra Priya Shaji

study the dataset and the associated description of the data (i.e. “data dictionary”). You may need to look around a bit, but it’s there! You should take the data, and create a data frame with a subset of the columns in the dataset. You should include the column that indicates edible or poisonous and three or four other columns. You should also add meaningful column names and replace the abbreviations used in the data—for example, in the appropriate column, “e” might become “edible.” Your deliverable is the R code to perform these transformation tasks.
