Question

After reading the lecture note of Chapter 11 (Simple Linear Regression). Please give three examples of possible topics about regression.

Follow this format:

One Y variable with several X variables (at least two X variables).

For example:

1. Example 1: The "house price" (consider as "Y" ) may be related to "area of the house" (consider as "X1"), "lot size" (consider as "X2"), "built year" (consider as "X3"), "number of bedrooms" (consider as "X4").

2. Example 2: The "starting salary" (consider as "Y") may be related to "education level" (consider as "X1"), "school rating" (consider as "X2"), "major ranking" (consider as "X3").

Answer 1

Example 1: The "salary of teacher" (consider as "Y") may be related to "Years of experience" (consider as "X1"), "Rating of Teacher" (consider as "X2"), "Masters" Whether teacher has masters degree or not (consider as "X3", takes value 0,1).

Example 2: The "Number of children couple have" (consider as "Y") may be related to "Year to their marriage" (consider as "X1")

Example 3: The "total cost" (consider as "Y") may be related to "size of order" (consider as "X1").
