ToFind:The types of music students would like to listen to the next school dance. How would you conduct a survey to find the music preferences of your entire school?

Answer to Problem 24PPE
Thechosen random sampling method to choose the sample so that the sample isunbiased.
Explanation of Solution
Calculation:
To know the music preference of entire school;
We conduct a survey by asking the question, "What type of music would like to listen to the some student of the school randomly. Also, keeping in the mind the student of the school represent the population, and we conduct a survey in some student which represent the sample.
To know the sampling method can you use to choose an unbiased sample.
Use the random sampling method is used so that the sample is unbiased.
If you use the random sampling method, then the result of the sample is unbiased, since therandom sampling method does not contain any assumption, which is either true of not true.
Therefore we choose random sampling method to choose the sample so that the sample isunbiased.
To know thehow survey questions that is not biased.
First we select the some student of the school randomly, and then write the survey question such that it does not contain any assumption, because assumption may or may not be true.
By the definition of bias survey question, if the survey contains assumption then it is bias.
Therefore, we write the question, so that it does not contain any assumption or any influenceword which influence the answer of the question.
