Relationship between relative frequency and probability of an event?
The relative frequency is an estimate of the probability of an event.
What is law of large numbers?
when a probability experiment is repeated a large number of times, the relative frequency probability of an outcome will approach its theoretical probability.
Is relative frequency similar to the concept of probability?
The relative frequency of of an event is one possible measure of its probability.
What is the definitions of a theoretical probability?
To me, the theoretical probability is what is termed the classical probability. This says the probability is the number of ways an event can occur divided by the number of possible events. Forexample, flip a coin. The theoretical probability for heads is 1/2. However, flip a coin 10 times and you will probably not get 5/10 (or 1/2). Doing the actual experiment to determine the probability is called relative frequency approximation.
Why is relative frequency different to probability?
It is not! It is one measure of probability.
What is the calculated probability based on relative frequency?
It is the empirical or experimental probability.
Relative frequency formula?
Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.
Does relative frequency probability use group information and apply it to single cases?
Yes, relative frequency probability uses group information and applies it to single cases.
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).
Is relative frequency the same as probability?
If we are talking of an aleatory event, and its relative frequency obtained over a large number of trials, yes.
What is the difference between the terms 'probability' and 'relative frequency'?
If an action is repeated n times and a certain event occurred b times then the ratio b/n is called the relative frequency.Where as theoretical probability is used to determine the number of ways that the event can occur if an experiment is repeated a large number of times.
What is an example of relative frequency probability?
Flip a coin 1000 times, counting the number of 'heads' that occur. The relative frequency probability of 'heads' for that coin (aka the empirical probability) would be the count of heads divided by 1000. Please see the link.
