This module provides a lab of Linear Regression and Correlation as a part of Collaborative Statistics collection (col10522) by Barbara Illowsky and Susan Dean.

Student learning outcomes:
The student will calculate and construct the line of best fit between two variables.
The student will evaluate the relationship between two variables to determine if that relationship is significant.
Collect the data
Survey 10 textbooks. Collect bivariate data (number of pages in a textbook, the cost of the
textbook).
Complete the table.
Number of pages
Cost of textbook
Which variable should be the dependent variable and which should be the independent
variable? Why?
Graph “distance” vs. “cost.” Plot the points on the graph in "Analyze the Data". Label both axes with
words. Scale both axes.
Analyze the data
Enter your data into your calculator or computer.
Write the linear equation below, rounding to 4 decimal places.
Calculate the following:
=
=
correlation =
=
equation:
=
Is the correlation significant?
Why or why not? (Answer in 1-3 complete sentences.)
Supply an answer for the following senarios:
For a textbook with 400 pages, predict the cost:
For a textbook with 600 pages, predict the cost:
Obtain the graph on your calculator or computer. Sketch the regression line below.
Discussion questions
Answer each with 1-3 complete sentences.
Does the line seem to fit the data?
Why?
What does the correlation imply about the relationship between the number of pages
and the cost?
Are there any outliers? If so, which point(s) is an outlier?
Should the outlier, if it exists, be removed? Why or why not?
Questions & Answers
I'm interested in biological psychology and cognitive psychology
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
