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
interval
char, short, long, float, double.
Inclusive methods of grouping data include the endpoints of each class interval, meaning that the upper boundary of one interval is included in that interval and the lower boundary of the next. For example, an interval of 10-20 would include both 10 and 20. In contrast, exclusive methods do not include the upper boundary of one interval in that interval; thus, the same interval would be represented as 10-20, where 20 is considered part of the next interval. This distinction affects how data is categorized and analyzed, particularly in statistical calculations.

Data flexibility is a quality characteristic.
Quantitative data deals with numbers. It is data that can be measured. An example of this is: 51% of the world's population is female.
An inclusive series in statistics refers to a method of grouping data where both the lower and upper boundaries of each class interval are included in that interval. For example, in an inclusive series, a class interval might be represented as 10-20, meaning that both 10 and 20 are part of that interval. This contrasts with an exclusive series, where the upper boundary is not included. Inclusive series are often used when summarizing data to ensure clarity in how data points are categorized.
Data comes in various sizes and shapes. Two of them are Interval and Ratio. Interval is a measurement where the difference between two values is meaningful and follows a linear scale. For example: in physics, temperature 0.0 on either F or C does not mean 'no temperature'; in biology, a pH of 0.0 does not mean 'no acidity'. Interval data is continuous data where differences are interpretable, ordered, and constant scale, but there is no 'natural' zero. Ratio is the relation in degree or number between two similar things or a relationship between two quantities, ordered, constant scale, with natural zero. Ratio data is interpretable. Ratio data has a natural zero. A good example is birth weight in kg. The distinctions between interval and ratio data are slight. Certain specialized statistics, such as a geometric mean and a coefficient of variation can only be applied to ratio data.
Interval data is data divided into rangers, where the distance between intervals is the important data being looked at. In experiments this is used to help show if data's closely collected around an expected area or not.
An example of data that can be transformed from one level of measurement to another is temperature. For instance, temperature measured in degrees Celsius (an interval scale) can be converted into Fahrenheit or Kelvin, maintaining the same relative differences. Additionally, if we categorize temperatures into qualitative groups (e.g., "cold," "warm," "hot"), the interval data can be transformed into an ordinal level of measurement.
