The figure below may help you understand the difference between discrete and continuous data? Heck, Yeah! Tell whether the relation is a function. I think the point being made is that the exact time it takes to do something is a continuous, while any sort of measurement and recording of the time, no matter how precise it may seem, is discrete since we have to cut off that precision at some point when measuring. Neither piece of data is continuous nor discrete. If a continuous function has a graph with a straight line, then it is referred to as a linear function. the case, instead of saying the Continuous functions, on the other hand, connect all the dots, and the function can be any value within a certain interval.
