hat is a factor variable? When would you want to use a factor variable? Factor variable is the main way to represent a nominal scale variable. We use factor variables when t here's no relationship between the value stored in the nominal variable and the different possibilities (categories). The factors are the variable in R, which takes the categorical variable and stores data in levels. The primary use of this function can be seen in data analysis and specifically in statistical analysis. Also, it helps to reduce data redundancy and to save a lot of space in the memory. . Factors are the main way to represent a nominal scale variable. Nominal variables store values that have no relationship between the different possibilities (categories). Levels refer to the range of categories represented in the groups Factor variables in R represent categorical data by assigning each category a numerical value known as a level. Converting a variable to a factor variable in R ensures it is treated as categorical rather than numeric, preventing accidental mathematical operations on the data. answer in 2 parts , what is a factor variable?
