Accepted Answer

All right, hello, everyone. So, this question is asking us to determine whether the data given in the following analysis are from a discrete or continuous data set. While analyzing patient health data, a researcher records the number of time in seconds between consecutive heartbeats to study irregularities in heart rhythms. Option A, the multiple choice says continuous. Option B says discreet. Option C says neither and option D says both. So first, what is the difference between these two types of data? Well, Recall that continuous data can take any value within a given range and is often measured. Examples of this are height, time, and temperature. Discrete values on the other hand, are countable. And so discrete data must be reported as a whole number, as an integer. An example of this would be the number of students in a classroom. And so notice what I made a point of mentioning earlier, right? Discrete values can only be integers, whereas continuous data can take on the form of a decimal, because it can be any value within a given range. So going back to the example given, here our data is time in seconds, and time can take on. Any value within a given range including decimals. So therefore, time, because it's not limited to whole numbers, is considered continuous, meaning option A is correct here. And there you have it. So with that being said, thank you very much for watching and I hope you found this helpful.
