These different types of data are nominal, ordinal, interval and ratio data. These different variances of data vary in complexity of obtaining. Interval Level of Measurement. The interval level of measurement includes all the properties of the nominal and ordinal level of measurement but it has an additional property that the difference (interval) between the values is known and constant size. In this measurement 0 is used as an arbitrary point. Nakatulong ba sa'yo ang video na 'to? You can support the channel in producing better educational content for both students and teachers.
