When should you use relative frequency such as percentages in comparing two distributions?
ChristieMoore
When comparing the spread or variability rather than the location or mean.
For example, men's heights and women's heights. You "know" that, on average, men will be taller but you may want to see if the variability within the two sets is the same or different.

Why would relative frequency be better than frequency while comparing two different groups?
you are aw some * * * * * Sadly you are not since you can't even spell the word. Relative frequency would be better because the two groups may be of different size.
What is the name for a relative frequency distribution shown by heights?
Are you talking about a histogram of the relative frequency distribution.
Relative frequency formula?
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
This measurment is recorded in percentages?
relative humidity
What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
Difference between frequency table and relative frequency table?
Frequancy Tables only use whole numbers while relative frequency tables use exact percentages or decimals.
Frequency and cumulative frequency are two types of what?
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.

Which measurements are recorded in percentages?
Relative humidity is recorded in percentages.
Is the relative frequency of surveyed girls that have sports as their activity a joint relative frequency or a marginal relative frequency?
Yes
How can the relative and absolute ages of rock be determined?
By comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
What is the Difference in relative frequency and percentage frequency?
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
What measurements is recorded in percentages?
relative humidity
What is the meaning of a relative frequency of 0?
Relative frequency of an event is the frequency of that event divided by the total number of observations. Therefore, a relative frequency of 0 implies the event has zero proportion (or probability).
The first class in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2What does the 0.2 value indicate?
The sum of the relative frequencies must equal 1 (or 100%), because each individual relative frequency is a fraction of the total frequency. The relative frequency of any category is the proportion or percentage of the data values that fall in that category. Relative frequency = relative in category/ total frequency It means a number in that class appeared 20% of the total appearances of all classes
