Question
Use R studio and the data provided to CREATE VISUALS to evaluate the variables/factors that may affect the quality of life (such as fitness level, happiness, stress, productivity).
1.Come up with 5 hypotheses about factors that affect the daily quality of life.
2. Clean the data. Data can be found: https://drive.google.com/file/d/0B1D66qK8jxd0bUhMRHItLS1QQzA/view?usp=sharing
3. Design and create a set of visualizations within a dashboard/storyboard that provides insight into validating the hypotheses.
Requirements:
- must outline 5 questions that can be evaluated using a data-driven approach
- with at minimum 1 interactive graphical element
Explanation / Answer
Factors in R are stored as a vector of integer values with a corresponding set of character values to use when the factor is displayed. The factor function is used to create a factor. The only required argument to factor is a vector of values which will be returned as a vector of factor values. Both numeric and character variables can be made into factors, but a factor's levels will always be character values. You can see the possible levels for a factor through the levels command.To change the order in which the levels will be displayed from their default sorted order, the levels= argument can be given a vector of all the possible values of the variable in the order you desire. If the ordering should also be used when performing comparisons, use the optional ordered=TRUE argument. In this case, the factor is known as an ordered factor.The levels of a factor are used when displaying the factor's values. You can change these levels at the time you create a factor by passing a vector with the new values through the labels= argument. Note that this actually changes the internal levels of the factor, and to change the labels of a factor after it has been created, the assignment form of the levels function is used. To illustrate this point, consider a factor taking on integer values which we want to display as roman numerals.
