# Positive linear relationship

Chapter 4 Lab For this assignment, you will work to refine and build your understanding of the four types of a relationship variables can have: 1. Positive linear relationship 2. Negative linear relationship 3. Curvilinear relationship 4. No relationship Remember that these relationships are between TWO DIFFERENT variables. Thus, for each of the 4 relationships, you will need to select two different variables (do not reuse the same variables). Recall that variables have to vary, so there needs to several levels to each variable. It cannot be something with one level (refer to our lecture and/or textbook). For each example, I want you to identify the name of your variable and your operational definition of it. For example, your variable might be stress levels. How could we operationally define this? We could ask people to report how stressed they are on a level from 1-10. We could have people do a mouth swab and get cortisol levels. There a several ways to measure (or operationally define) stress. This will be true of your variables as well. Lastly, provide an explanation of how you expect the two variables are related to one another. For example, “I predict that an increase in degrees (temperature) will be positively associated with an increase in ice cream sales.” Positive Linear Relationship: Variable 1 Variable 2 What is the name of your variable?
