The exact age is a continuous variable, but age is often rounded down to the closest integer.Why is age an example of a continuous variable?
Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places. What is this? If you know someone's birth date, you can calculate their exact age including years, months, weeks, days, hours, seconds, etc.Is age at last birthday a continuous variable?
Sometimes continuous data are given discrete values at certain thresholds, for example age a last birthday is a discrete value but age itself is a continuous quantity; in these situations it is reasonable to treat discrete values as continuous.- Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.
