What is the problem of random sampling?
With random sampling, you are hoping to get a representative sample of a whole, however statistically you could get a sample that is very different from the whole it was selected from. The larger the sample proportion of the whole, the better your sample will be. For example, a sample of 10 out of 100 is not as good as 20 out of 100. The bigger the sample the closer to the actual whole average you will get.
What is an example of a biased sample?
In math, a biased example could be when, someone asks only males to answer "do you like this product." its when the people chosen to answer the survey/sample is not random
How do I prevent a speech to my classmates?

Example of stratified random sampling?
In stratified sampling, the population to be sampled is divided into groups (strata), and then a simple random sample from each strata is selected. For example, a state could be separated into counties, a school could be separated into grades. These would be the 'strata'.
Is polling 648 parents and 648 non parents a simple random sample?
Yes, such numbers could be used to get a reasonable cross-section of opinion.
Why is it important to ensure that an experimental sample is totally random?
To ensure that the results produced from your sample are fair and true. For example, if you had to pick 10 random numbers between 1 and 6, you could just say numbers that come into your head, but that wouldn't be random because you're choosing the numbers. A more random and fair way would be to roll a die 10 times and use those numbers, because you are in no way picking the numbers.
Is systematic sampling biased?
Often not, but it is important to check that there is no systematic pattern in the skip.To take an unlikely example, suppose you wanted to sample the values of 10% of houses on a street with 200 houses on it. A possible systematic sampling scheme would be to select a random house number to start with and then select every 20th house number (looping back when the number exceeds 200). If the first house number is odd then all houses in the sample are odd numbered and, therefore, on the same side of the street. If the street runs East-West, the sample could consist exclusively of South-facing gardens - attracting a price premium!
How could you conduct a school survey without questioning every student in the school?
You could consider using a random sampling method to select a representative sample of students. This could involve randomly selecting a certain number of students from each grade level or class to participate in the survey. Another option could be to use an online survey platform where students can voluntarily participate. This method provides a broader reach and allows students to respond at their convenience.
What is the sample in the study of cell phone and passenger conversation in simulated driving?
It could depend on what the study was specifically focused on. If it is focused on teen drivers alone, then the sample would be composed of a random selection of teenaged drivers. If it is testing the overall population of drivers, then there would be a random sample of those people.

Could your classmate be gay?
Yes. Between 5 to 10% of people are gay or bisexual. It might be that your classmates are not old enough to realise their sexual orientation, but it is also quite possible that they do. So yes, some of your classmates could be gay.
