Objective
Use data from a survey of students to perform exploratory data analysis and to evaluate the performance of different approaches to a statistical analysis.
Background
The following data are a mixture of surveys from a small liberal arts school on the West Coast. Each semester students in introductory statistics courses complete a survey. One of the questions is the number of siblings in their immediate family. The results of the survey are similar each semester, but results have been combined in a haphazard manner so that there is no chance any particular class can be identified.
The Task
Estimate the average number of siblings for the general population.
