19. We consider just two main types of variables in this course. Another example would be that the lifetime of a C battery can be anywhere from 0 hours to an infinite number of hours (if it lasts forever), technically, with all possible values in between. (representing the countably infinite case).\r\n \t
Continuous data represent measurements; their possible values cannot be counted and can only be described using intervals on the real number line. Data can be numbers that act as names rather than numbers (for example, phone numbers with dashes: 300-453-1111), resulting in qualitative data. Telephone numbers need to be stored as a text/string data type because they often begin with a 0 and if they were stored as an integer then the leading zero would be discounted. The list of possible values may be fixed (also called finite); or it may go from 0, 1, 2, on to infinity (making it countably infinite).For example, the number of heads in 100 coin flips takes on values from 0 through 100 (finite case), but the number of flips needed to get 100 heads takes on values from 100 (the fastest scenario) on up to infinity (if you never get to that 100th heads). For example, rating a restaurant on a scale from 0 (lowest) to 4 (highest) stars gives ordinal data.\r\n\r\nOrdinal data are often treated as categorical, where the groups are ordered when graphs and charts are made.
