When comparing large data sets.

Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
Use %RSD when comparing the deviation for popolations with different means. Use SD to compare data with the same mean.
