A variable is a number that can change in a given problem. There are different types of variables used in scientific or mathematical methods, such as the dependent and independent variable. The independent variable can take values or numbers freely; whereas the dependent variables are the variables that change due to a change in another variable in the system.
The mode is a number or value that happens most frequently in a set of data.
