Study Notes
Relative Frequency (A Posteriori)
Definition:
- Relative frequency is a method of estimating probability based on the results of repeated trials or experiments.
- It is also known as a posteriori probability, as it is calculated after the experiment has been conducted.
Key Concepts:
- Frequency: The number of times a particular outcome occurs in a series of trials.
- Relative Frequency: The ratio of the frequency of a particular outcome to the total number of trials.
Formula:
- Relative Frequency (RF) = Frequency of Outcome / Total Number of Trials
Example:
- A coin is tossed 10 times, and the outcome is heads 7 times. To calculate the relative frequency of getting heads:
- Frequency of Outcome (Heads) = 7
- Total Number of Trials = 10
- RF = 7/10 = 0.7
Interpretation:
- The relative frequency of 0.7 indicates that the probability of getting heads is approximately 70% based on the results of the 10 trials.
- As the number of trials increases, the relative frequency should approach the true probability of the outcome.
Advantages:
- Relative frequency is a simple and intuitive method for estimating probability.
- It is based on actual data and can provide a good estimate of probability when the number of trials is large.
Limitations:
- Relative frequency is sensitive to the number of trials. A small number of trials may not provide a reliable estimate of probability.
- It is not a theoretical probability, but rather an estimate based on empirical data.
