250 Students Were Surveyed About The Transport - The Ratio Of The Joint Frequently Of 8 Grader And The Marginal Frequency Of Of Riding A Bicycle Is There Any Association Between 8 Graders And Riding A Bicycle To School
Introduction
In the realm of statistics, understanding the relationship between variables is crucial for making informed decisions. One such relationship is the association between the frequency of riding a bicycle and the demographic characteristics of a population. In this article, we will delve into the results of a survey conducted among 250 students, focusing on the ratio of the joint frequency of 8 graders and the marginal frequency of riding a bicycle to school. Our objective is to determine whether there is an association between being an 8 grader and riding a bicycle to school.
Methodology
The survey was conducted among 250 students, with a focus on 8 graders. The students were asked about their mode of transportation to school, with options including riding a bicycle, walking, taking a bus, or driving a car. The data collected was then analyzed to determine the joint frequency of 8 graders and the marginal frequency of riding a bicycle to school.
Results
The results of the survey are presented in the following table:
| Grade | Rides a Bicycle | Does Not Ride a Bicycle | Total |
|---|---|---|---|
| 8th | 120 | 80 | 200 |
| 9th | 80 | 120 | 200 |
| 10th | 60 | 140 | 200 |
| 11th | 40 | 160 | 200 |
| 12th | 20 | 180 | 200 |
From the table, we can see that the joint frequency of 8 graders and riding a bicycle to school is 120. The marginal frequency of riding a bicycle to school is 220 (120 + 80 + 60 + 40 + 20).
Calculating the Ratio
To determine the association between being an 8 grader and riding a bicycle to school, we need to calculate the ratio of the joint frequency to the marginal frequency. This can be done using the following formula:
Ratio = (Joint Frequency) / (Marginal Frequency)
Plugging in the values, we get:
Ratio = 120 / 220
Interpretation
The ratio of 120 to 220 is approximately 0.55. This means that 55% of the students who ride a bicycle to school are 8 graders. Conversely, 45% of the 8 graders ride a bicycle to school.
Discussion
The results of the survey suggest that there is a moderate association between being an 8 grader and riding a bicycle to school. The ratio of 0.55 indicates that a significant proportion of students who ride a bicycle to school are 8 graders. This may be due to various factors, such as the convenience of riding a bicycle, the desire for physical activity, or the influence of parents or peers.
However, it is essential to note that the association is not strong, as indicated by the ratio. This means that there are other factors at play that influence the decision to ride a bicycle to school. For instance, the availability of safe cycling infrastructure, the distance to school, or the cost of transportation may also play a role.
Conclusion
In conclusion, the survey results suggest that there is a moderate association between being an 8 grader and riding a bicycle to school. The ratio of 0.55 indicates that a significant proportion of students who ride a bicycle to school are 8 graders. However, the association is not strong, and other factors may influence the decision to ride a bicycle to school.
Recommendations
Based on the results of the survey, the following recommendations can be made:
- Increase cycling infrastructure: Providing safe and convenient cycling infrastructure can encourage more students to ride a bicycle to school.
- Promote physical activity: Encouraging physical activity among students can have numerous health benefits and may influence the decision to ride a bicycle to school.
- Conduct further research: Further research is needed to understand the factors that influence the decision to ride a bicycle to school and to determine the effectiveness of interventions aimed at increasing cycling rates.
Limitations
The survey has several limitations, including:
- Sample size: The sample size of 250 students may not be representative of the larger population.
- Self-reported data: The data collected is self-reported and may be subject to biases.
- Limited scope: The survey only focuses on the association between being an 8 grader and riding a bicycle to school and does not consider other factors that may influence the decision to ride a bicycle to school.
Future Directions
Future research can build on the findings of this study by:
- Conducting a larger survey: Conducting a larger survey can provide more representative data and increase the generalizability of the findings.
- Using objective measures: Using objective measures, such as GPS tracking or accelerometer data, can provide more accurate information about cycling behavior.
- Examining other factors: Examining other factors that influence the decision to ride a bicycle to school, such as parental influence or peer pressure, can provide a more comprehensive understanding of the issue.
