What is the relationship between relative frequency and cumulative frequency?
frequency plot - number of counts relative frequency - number of counts/ total counts cumulative frequency - number of counts that are cumulatively summed cumulative relative frequency that are cumulatively summed. Examples: Let y = accidents per day for one week, and x = days of the week (1 to 7) y = (0, 0, 1, 2, 1, 5,1) for X = 1, 2, ... 7 frequency counts y = (0,0, 0.1,0.2,0.1, 0.5, 0.1) relative frequency y = (0,0,1,3,4,9,10) = cumulative frequency y = (0, 0, 0.1,0.3,0,0.4,0.9,1) cumulative relative frequency
Is the relative frequency of surveyed girls that have sports as their activity a joint relative frequency or a marginal relative frequency?
Yes
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.
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
What is the difference between frequency distribution and relative frequency distribution?
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.

Yes
The sum of all the relative frequencies of a distribution will always add up to 1?
Yes they doHere are some properties of relative frequency:(a) The relative frequency of each outcome is a number between 0 and 1.(b) The relative frequencies of all the outcomes add up to 1..

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.

What is the ratio of a frequency to its total frequency?
The ration of a frequency to its total frequency is called relative frequency.
Is relative frequency the quotient or product of a frequency?
It is a product.
How is a frequency distribution converted to a relative frequency distribution?
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
Is relative frequency similar to the concept of probability?
The relative frequency of of an event is one possible measure of its probability.
