StatCrunchU

Welcome to StatCrunchU!

StatCrunch University (StatCrunchU) is a large fictitious university with 46,000 virtual undergraduate students. The tools on this page allow you to administer the student survey shown below to a sample of StatCrunchU students. Use your statistics skills to try to better understand this population. Feel free to share any interesting insights with the StatCrunchU group, which is open to all StatCrunch members. Keep in mind that it is very unlikely that any two samples will be exactly the same, so results may differ somewhat from user to user.

Here are a few questions (there are many more) to consider about the StatCrunchU student population:

What is the proportion of females at StatCrunchU? Determine a range of plausible values for this proportion. Is this proportion significantly larger than 0.5?
How are the students distributed across the classes of Freshman (1), Sophomore (2), Junior (3) and Senior (4)? Does the proportion of females change across the classes?
What does the distribution of credit hours look like? Does the mean number of credit hours per student appear to be significantly below 15 hours? Does the distribution of credit hours appear to be impacted by gender or class?
What is the proportion of students at StatCrunchU that work? For those that do work, characterize the distribution of the number of hours worked per week. For those students that work, also describe the relationship between the number of hours worked per week and the number of credit hours taken. Does this relationship appear to differ for full time students (enrolled in 12 or more credit hours) and part time students (enrolled in less than 12 credit hours)?
What is the proportion of students at StatCrunchU that have loans? For those that do have loans, characterize the distribution of the loan amounts. Do gender and/or class have an impact on the distribution of loan amount? For students that work, is there a relationship between the amount of loans they have and the number of hours per week that they work?
What is the proportion of students at StatCrunchU that have credit card debt? For those students who have credit card debt, does the amount of credit card debt appear to be influenced by any one or any combination of the other variables?
