King who goes to Chris Hadfield makes a blog post that claims 40% of students from Ryerson High School do not know how to drive. He conducted the survey by asking one class of 10 students at Bishop Reding who volunteered. Why is this source not reliable?
This source is not considered reliable for a few reasons:
1. Sample size: The king's survey only included one class of 10 students from a different school, Bishop Reding, which is not the same as Ryerson High School. This small sample size may not be representative of the entire student population of Ryerson High School.
2. Non-random selection: The survey was only conducted with students who volunteered. This means that the students who participated in the survey may not be representative of the overall population. It is possible that those who volunteered may have a stronger interest or skills in driving, while those who do not know how to drive may have opted out of the survey.
3. Bias: The fact that the claim is made by a king raises questions about potential bias or motivation behind the claim. It's essential to consider the source's credibility and whether there might be any personal or political biases influencing the blog post.
To evaluate the reliability of a source, it's important to consider factors like sample size, random selection, and potential biases. To obtain more reliable information on the topic, it would be better to look for studies or surveys conducted by impartial organizations that ensure a larger and more diverse sample of students from Ryerson High School.
