What is the convenient scale and interval to use for graphing each set of data set?
It can be data over any single interval in the set of real numbers.
You find the the smallest and largest values. The interval is the largest minus the smallest.
In principle, yes. It may require interpolation within the central interval.

What is the convenient scale and interval to use for graphing each set of data set?
The answer will depend on the data values: there is no rule that fits all situations.
It can be data over any single interval in the set of real numbers.
You find the the smallest and largest values. The interval is the largest minus the smallest.
In principle, yes. It may require interpolation within the central interval.

to find an interval you have to subtract the first two number from each other for example 5 10 15 20 the interval for this set of data is 5
Range tells you the interval in which the f(x) values are found.
Interval notation is a method of writing down a set of numbers. An example of this is all numbers that are greater than five.Ê
A good way to assess what is a reasonable interval when graphing data is to see if there are any common factors in the data set. In this case 5, 10, 30, 40 and 20 are all clearly divisible by 5. Therefore, 5 would be a reasonable interval to use when graphing the data.
If none of the numbers in a set of data are repeated you have two options: Options 1: leave the data set as it is and call every value a mode. One instance when the mode is hardly a useful measure. Option 2: Group the data and find the class interval with the highest frequency density. This would be the modal interval. Note, though, that the class intervals that you choose will influence the result.
