As long as you You might have to get even Students will also determine why a table or graph is nonproportional. to cross the finish line. Looking at this graph, you see that it doesn't have separate and distinct points, but one continuous line that connects all the dots, so this is a continuous function. value it could take on, the second, the third. Because they are not connected and the points are distinct values, this function is a discrete function. Continuous Data can take any value (within a range) Examples: A person's height: could be any value (within the range of human heights), not just certain fixed heights, Time in a race: you could even measure it to fractions of a second, A dog's weight, The length of a leaf, Lots more! Your definit, Posted 10 years ago. I think you see what I'm saying. Continuous variable [ edit] A continuous variable is a variable whose value is obtained by measuring, i.e., one which can take on an uncountable set of values. For example, number of students in a class, number of players required in a team, etc. Y is the mass of a random animal The minimum is 0 students and the maximum is 50. Discrete random variables are more common than we think. Problem 4 . Continuous random variables, on the other hand, can take on any value in a given interval. 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. For example, youre measuring the colours of one stoplight at an intersection. This will help students decide, using the independent variable, if the scenario is discrete or continuous. i) No one gets more than one gift. Unlike discrete data, continuous data are not limited in the number of values they can take. Some other examples of continuous variables are: A qualitative variable can also be discrete, but it can never really be continuous. This a great activity to post around the, Connect the concept of independent and dependent variables to domain and range of relations. 6. Discrete Linear Word Problems.
