Question

Okay pleaseee I need help with JUST choosing 3 variables. I don't need help with the project but I am SO stuck on choosing 3 variables (2 independent and 1 dependant) that are biological in nature that could possibly correlate??? That has me so stuck so any ideas would be GREATLY appreciated. The rest I can do!

This is the projects info just so you have a better idea of what options for the 3 variables are suitable!

For this project you will determine if a linear relationship exists between three quantitative​ variables, you will then model the relationship and try to make predictions using your model.

​Remember:

- Your variables must be quantitative. They cannot be​ qualitative, i.e. categorical variables.

- Your variables must be biological in nature.

- Two of your variables must be independent, and the third must be dependent. You will be using the two independent variables to predict values of the dependent variable after you collect and analyze your data.

Please pick variables and a population that will make it easy for you to collect data.

For this project you will collect data for all 3 variables from 25 individuals. In the first project​ write-up you will be asked to include an explanation of the context of the​ data, i.e. how it was collected and why it was collected.

Answer 1

This is a purely hypothetical situation, but could be interesting

Independent Variables :

X1 : Number of brothers the lady of the house has

X2 : Number of brothers the gentleman of the house has

Dependent Variable :

Y : Number of male children the couple have together
