We don’t have your requested question, but here is a suggested video that might help.

Identify any bias in each sampling method. The student government wants to find out how many students have after-school jobs. A pollster interviews students selected at random as they board buses at the end of the school day.

Match the sample of students with the correct sampling method. every third student on the class list Orandom convenience @systematic cluster

Identify which of these types of sampling is used: random, systematic, convenience, stratified, or cluster. A student of the author conducted a survey on driving habits by randomly selecting three different classes and surveying all of the students as they left those classes.

Now, in this question, it is given that the author survey the sample from the Population Office statistics class by identifying the groups of males and females. This looks like stratified sampling or cluster sampling. Let's move on to see, then randomly select five students from these groups. Not all of them were selected, but five were selected. So this is stratified samples. This is a stratified sample, a stratified sample.

All right. So we have to identify the type of something used. A school official divides the student population into five classes, freshman, sophomore, junior, senior and graduate students. Okay, So he has divided the population into five different categories based on the number of years they're studying or they have studied or in which year they're studying. So sounds like stratified sampling. Let us see what happens. The official takes a simple random sample from each class and asked the members opinions regarding student services. Again, this is a clear example of stratified sampling. What he has done is in order to make the sample representative of all the five classes. He has divided the population into five different groups and randomly selected samples from those five groups. So the World Temple is going to be a mixture of people selected from all these five groups, so that all the five groups are appropriately uh represented by the world sample. So this is stratified sampling. This is our answer.

This question asks us determine whether each sample is random, systematic or stratified. What we know is that I would say this sample is stratified and the reason why because they're separating the population into stronger groups and then

The student government wants to find out how many student that mean The government lost the number moment once the exact data exact number. So for this, he should take each and every each and every student data. So for this, a pollster interviews Eastern selected at random as the board was. So he should cocoa each and every each and every your students interview. But he takes randomly, so that means here is biased in data collection.
