Introduction

In this article, we will delve into the world of statistics and explore how to find the joint relative frequency of being male and attending a drama movie. We will use a table that shows the number of males and females who attended two different movies: Action and Drama. Our goal is to understand the relationship between the gender of the attendees and the type of movie they watched.

The Table

	Action	Drama	Total
Male	120	80	200
Female	180	120	300
Total	300	200	500

Understanding the Table

The table shows the number of males and females who attended two different movies: Action and Drama. The total number of attendees for each movie is also provided. We can see that there are 200 males and 300 females in total, and 500 attendees in total.

Finding the Joint Relative Frequency

To find the joint relative frequency of being male and attending a drama movie, we need to follow these steps:

Identify the relevant data: We need to identify the number of males who attended the drama movie, which is 80.
Calculate the total number of attendees: We need to calculate the total number of attendees for the drama movie, which is 200.
Calculate the joint relative frequency: We can calculate the joint relative frequency by dividing the number of males who attended the drama movie by the total number of attendees for the drama movie.

Calculating the Joint Relative Frequency

To calculate the joint relative frequency, we can use the following formula:

Joint Relative Frequency = (Number of males who attended drama movie) / (Total number of attendees for drama movie)

Plugging in the values, we get:

Joint Relative Frequency = 80 / 200 Joint Relative Frequency = 0.4

Interpretation

The joint relative frequency of being male and attending a drama movie is 0.4, or 40%. This means that 40% of the attendees for the drama movie were males.

Conclusion

In this article, we used a table to explore the relationship between the gender of the attendees and the type of movie they watched. We found the joint relative frequency of being male and attending a drama movie by following a series of steps and using a formula. The joint relative frequency was found to be 0.4, or 40%. This information can be useful for movie producers and marketers who want to understand their audience better.

Discussion

The table and the analysis we performed can be used to discuss various topics related to statistics and data analysis. Some possible discussion topics include:

Comparing the joint relative frequency of being male and attending a drama movie to the joint relative frequency of being female and attending a drama movie: We can compare the joint relative frequency of being male and attending a drama movie to the joint relative frequency of being female and attending a drama movie to see if there are any differences.
Analyzing the relationship between the gender of the attendees and the type of movie they watched: We can analyze the relationship between the gender of the attendees and the type of movie they watched to see if there are any patterns or trends.
Using the table to explore other statistical concepts: We can use the table to explore other statistical concepts, such as the mean, median, and mode.

Introduction

In our previous article, we explored the relationship between the gender of the attendees and the type of movie they watched using a table that shows the number of males and females who attended two different movies: Action and Drama. We found the joint relative frequency of being male and attending a drama movie to be 0.4, or 40%. In this article, we will answer some frequently asked questions related to the table and the analysis we performed.

Q&A

Q: What is the total number of attendees for the Action movie?

A: The total number of attendees for the Action movie is 300.

Q: What is the total number of attendees for the Drama movie?

A: The total number of attendees for the Drama movie is 200.

Q: What is the joint relative frequency of being male and attending the Action movie?

A: To find the joint relative frequency of being male and attending the Action movie, we need to divide the number of males who attended the Action movie (120) by the total number of attendees for the Action movie (300). The joint relative frequency is 0.4, or 40%.

Q: What is the joint relative frequency of being female and attending the Drama movie?

A: To find the joint relative frequency of being female and attending the Drama movie, we need to divide the number of females who attended the Drama movie (120) by the total number of attendees for the Drama movie (200). The joint relative frequency is 0.6, or 60%.

Q: Can we use the table to explore other statistical concepts?

A: Yes, we can use the table to explore other statistical concepts, such as the mean, median, and mode. For example, we can calculate the mean number of attendees for the Action movie by adding up the number of males and females who attended the movie and dividing by the total number of attendees.

Q: How can we use the table to analyze the relationship between the gender of the attendees and the type of movie they watched?

A: We can use the table to analyze the relationship between the gender of the attendees and the type of movie they watched by comparing the joint relative frequencies of being male and attending different types of movies. For example, we can compare the joint relative frequency of being male and attending the Action movie to the joint relative frequency of being male and attending the Drama movie.

Q: Can we use the table to make predictions about the number of attendees for future movies?

A: While we can use the table to make some predictions about the number of attendees for future movies, it is not a reliable method for making predictions. The table only shows the number of attendees for two specific movies, and it does not take into account other factors that may affect the number of attendees for future movies.

Conclusion

In this article, we answered some frequently asked questions related to the table and the analysis we performed. We hope that this article has been helpful in clarifying any questions you may have had about the table and the analysis. If you have any further questions, please don't hesitate to ask.
