Relative Frequency and Experimental Probability

In this video, Carlton introduces the concept of relative frequency, a form of experimental probability. He explains how relative frequency is calculated by dividing the number of times an event occurs by the total number of trials. Using examples like dice rolling and survey data, Carlton demonstrates how to compute relative frequency and interpret the results. The video concludes with instructions for the next session, where students will find the relative frequency for MBAs and master's degrees.

What is relative frequency?

• The likelihood of an event occurring based on theoretical calculations.

• The number of times an event occurs divided by the total number of trials.

• The total number of outcomes possible in an experiment.

• The difference between the highest and lowest frequency in a dataset.

How is relative frequency related to experimental probability?

• They are completely unrelated concepts.

• Relative frequency is a type of experimental probability.

• Experimental probability is calculated using relative frequency.

• They are both used to calculate theoretical probability.

In the dice roll example, how many times was a sum of 12 achieved out of 50 rolls?

• 24 times

• 12 times

• 50 times

• 35 times

What does the term 'frequency' refer to in the context of relative frequency?

• The sum of all possible outcomes.

• The probability of an event occurring.

• The number of times an event occurs.

• The total number of trials conducted.

How do you calculate relative frequency?

• Add the number of successful outcomes to the total number of trials.

• Divide the number of successful outcomes by the total number of trials.

• Multiply the number of successful outcomes by the total number of trials.

• Subtract the number of successful outcomes from the total number of trials.

What was the relative frequency of getting a sum of 12 in the dice roll example with 24 rolls?

• 0.12

• 0.08

• 0.83

• 0.17

What is the first step in calculating relative frequency?

• Count the number of successful outcomes.

• Divide the number of successful outcomes by the total number of trials.

• Multiply the number of successful outcomes by the total number of trials.

• Identify the total number of trials.

What is the purpose of calculating relative frequency?

• To calculate the total number of possible outcomes.

• To estimate the likelihood of an event based on experimental data.

• To find the average outcome of an experiment.

• To determine the theoretical probability of an event.

In the dice roll example, what was the relative frequency of getting a sum of 12 out of 30 rolls?

• 0.12

• 0.24

• 0.36

• 0.08

What is the significance of the total number of trials in calculating relative frequency?

• It determines the maximum possible frequency.

• It is irrelevant to the calculation.

• It is used to calculate the average frequency.

• It serves as the denominator in the relative frequency calculation.
