If a coin is flipped 20 times and a head comes up 7 times what is the relative frequency of a head coming up?
The relative frequency of an event is calculated by dividing the number of times the event occurs by the total number of trials. In this case, the coin was flipped 20 times, and heads appeared 7 times. Therefore, the relative frequency of getting heads is ( \frac{7}{20} ), which equals 0.35 or 35%.
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.
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.
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

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.
