For example, in a woman with a 21-day cycle, the follicular phase is likely seven days; in a woman with a 35-day cycle, the follicular phase is likely twenty-one days. (Note: It is possible for a luteal phase defect to shorten the length of the menstrual cycle â this will be discussed in a future article on Phase II.
The diatonic scales. The diatonic scale is most familiar as the major scale or the natural minor scale (or aeolian mode). The diatonic scale is a very important scale. Out of all the possible seven note scales it has the highest number of consonant intervals, and the greatest number of major and minor triads.he diatonic scale is a very important scale. Out of all the possible seven note scales it has the highest number of consonant intervals, and the greatest number of major and minor triads.
Interval scale data has order and equal intervals. Interval scale variables are measured on a linear scale, and can take on positive or negative values. It is assumed that the intervals keep the same importance throughout the scale.e can say that the temperature of 40 C is higher than 30 C, and an increase from 20 C to 40 C is twice as much as the increase from 30 C to 40 C. Counts are interval scale measurements, such as counts of publications or citations, years of education, etc. 1  Continuous Ordinal Variables.
