The article that I chose is “The Ultimate Halloween Candy Power Ranking” by fivethirtyeight.com, which can be found at this link: https://fivethirtyeight.com/features/the-ultimate-halloween-candy-power-ranking/
This article is about the results of a survey conducted by fivethirtyeight.com, in which over 200,000 participants were asked to rank their favorite Halloween candies. The survey aimed to determine the most popular Halloween candies in the United States, as well as any regional differences in candy preferences. The article also includes data visualizations and analysis of the survey results, including the distribution of candy popularity by chocolate or non-chocolate, hard or soft and by region. I have chosen the “The Ultimate Halloween Candy Power Ranking” dataset from fivethirtyeight.com. This dataset contains information on different Halloween candies and their popularity, based on a survey conducted by fivethirtyeight.com. I find this dataset interesting because it allows me to explore the preferences and opinions of people when it comes to Halloween candies.
i will do the following.
1-Read the data into R using the read.csv() function 2-Remove unnecessary columns that will not be used in the analysis 3-Rename columns to meaningful names 4-Replace any non-intuitive abbreviations used in the data 5-Check for missing values and handle them accordingly ——- I have studied the data and read the associated fivethirtyeight.com article. The dataset contains information on 85 different candies, including the candy’s name, its chocolate or non-chocolate category, whether it’s a hard or soft candy, and its overall ranking in the survey. The survey was conducted by fivethirtyeight.com in 2016, with over 200,000 participants. The data is provided in a CSV file on the GitHub site, and it is ready for analysis.
