Walter wants to learn more about the preferred salad ingredients of students in his
school. He surveys all students in his math class and finds that 4 prefer tomatoes,
14 prefer carrots, and 9 prefer cucumbers. What is the population and sample? Is
the sample a representative sample? Explain.

For example , If we want to calculate the average income of American data scientist , all American data scientists will be determine the population in this case,

A sample denotes a subset of population . When population is extremely large , the researcher draw a sample of the entire population and use this to analysis and study. So we can say a sample can represent a particular population.

Here, Walter surveys all students in his math class and finds that 4 prefer tomatoes, 14 prefer carrots, and 9 prefer cucumbers.

Population = All students in his School

Sample = Students in his class.

No, the sample is not a representative sample, it is the convenience sample.

It can be possible that his class has influence of him or students of other classes may like exactly different ingredients for salad like sprouts, fruit etc.
