Question text For this question, you will need to analyse data found in the data file df.csv (UCI Machine Learning Repository 2014). Download the data set by clicking on df.csv and then save it in a relevant location on your PC. Please note: Each time you attempt the quiz, a new randomised data set is provided in this question. If you are re-attempting this quiz, please ensure you download the new data set provided in this question and answer the questions based on the new data set. You will then need to import your data into jamovi (Sci/Health students) or R (Data Science students). There are three columns (variables) in df.csv, however we are only interested in the variable called health. There are 9595 rows in the data set. The health variable contains the current health status for all 9595 people included in the data set. A person’s health status can be classified as either “Very Bad”, “Bad”, “Fair”, “Good”, or “Very good”. Carry out the necessary analysis using either jamovi (Sci/Health students) or R (Data Science students) and answer the following questions. Where relevant, round your answers to one decimal place.
