These measures are calculated for the comparison of dispersion in two or more than two sets of observations. These measures are free of the units in which the original data is measured. If the original data is in dollar or kilometers, we do not use these units with relative measure of dispersion. These measures are a sort of ratio and are called coefficients. Each absolute measure of dispersion can be converted into its relative measure. Thus the relative measures of dispersion are:
- Coefficient of Range or Coefficient of Dispersion.
- Coefficient of Quartile Deviation or Quartile Coefficient of Dispersion.
- Coefficient of Mean Deviation or Mean Deviation of Dispersion.
- Coefficient of Standard Deviation or Standard Coefficient of Dispersion.
Coefficient of Variation (a special case of Standard Coefficient of Dispersion)

UPF
Is relative standard deviation an absolute value?

What is species evenness a measure of?
relative adundance
What is a pH?
It is the measure of relative acidity and alkalinity
Does relative humidity measure how hot it feels?
False
An instrument that measure relative humidity is called a?
psychrometer
What are the units that a sling psychrometer measure?
Relative humidity
Is relative frequency similar to the concept of probability?
The relative frequency of of an event is one possible measure of its probability.
Difference in Relative risk and risk ratio?
There is no difference between the two. Relative risk is the same as relative ratio. Commonly abbreviated as RR, relative risk/ratio is measure of absolute risk in one population as a proportion of absolute risk in another. It is a measure of the strength of association.
Mass number is?
It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
Why is relative frequency different to probability?
It is not! It is one measure of probability.
Who attempted to measure the relative distance to the moon and the sun?
nobody
