# How do I use descriptive statistics to describe when I don’t have an independent and dependent variable?

My question is very basic:

I understand linear regression and how to use it. I would like to know what to use in statistics when I don’t have a dependent and independent variable. For example, I understand how we could use height to predictic weight but I only have one variable. Take for instance if I have four people dividing up money. I want to show how closely the numbers are together. Each person is going to submit their opinion of how the money should be divided. I want to show how one person is way off from the others using descriptive statistics. These are percentages of the total.

# 4 90%, 2.5%, 2.5%, 2.5%

I skewed the data to make it obvious but I want statistical numbers to show that #1-#3 All agree for the most part and #4 is way off. Am I missing something that blantantly obvious of how you would use regression?

• Try calculating the intra class correlation coefficient, or if that is too heavy handed, try the mean and variance of Z-scores. – Jay Schyler Raadt Dec 23 '17 at 1:17
• Who gets the remaining 2.5%? – whuber Oct 17 '19 at 11:25
