What are the variables in regression? - ANSWER 1. Response 
(dependent) variable - one particular variable that we are 
interested in understanding or modelling, such as sales of a 
particular product. 
2. Predicting or Explanatory (independent) variable - set of other 
variables that we think might be useful in predicting or modelling 
the response variable (like the price of a product)

Regression analysis correct answers measures the impact of a set of variables on another variable. 
 
Largely concerned with ESTIMATING/predicting the population mean or average value of the dependent variable based on the known values of the explanatory variable 
 
There are two Variables X and Y, representing the same population. How does changing X effect Y 
e.g E(Y | Xi) = f (Xi)

A researcher wants to know if there was a relationship between student age and desire to complete a 
college degree. To answer this question, the researcher used a local community college as the sampling 
frame and then used stratified sampling to get a sample of students from 18 to 80 years old. Based on 
the information given, is there any potential bias in this study? 
a Yes, because the sampling frame does not match the intended population of the question. 
b Yes, because the sampling method...
