Create and post a crosstab of your variables and a measures of association table. 

Complete the following steps:

1. Post a brief explanation of your topic. Include your research question and a broad research hypothesis — that is, the relationship of IV to DV. (For example, educational attainment affects family income in US adults.)
2. Run a crosstab on your variables.  Be sure to explain your findings, including a description of the table, a calculation of the epsilons, and a discussion of the 10% rule.
3. Run the correct measure of association for your variables (Choose one – either Pearson R, Gamma, Phi, Cramer’s V or Lambda). Explain what the output means in terms of strength and direction of the relationship. Interpret Proportional Reduction of Error (PRE) using the following statement: Knowing the IV will reduce error in predicting the DV by *%.

Copy the crosstab and measure of association table into the discussion window or into a document (PDF, MS Word) and attach to discussion. If your table does not fit to the page, choose “copy special” and then “images” or take a screen shot of the table to copy/past into the window.

As a reminder, here are the guidelines for choosing your measure of association:

1. Both DV and IV are nominal variables: Lambda (when it is not a 2X2 table)
2. Both DV and IV are nominal variables and it is a 2X2 table: Phi
3. Both DV and IV are ordinal variables: Gamma
4. One variable ordinal or interval/ratio AND the other variable dichotomous nominal (like Yes/No, male/female, etc.): Gamma
5. One variable ordinal or interval/ratio AND the other variable nominal (not dichotomous, has more than 2 categories): Cramer’s V.
6. Both DV and IV are I/R variables: Pearson’s r

Biology in the News Assignment

The biology concepts presented in this course encourage you to make the connection between textbook biology and biology that appears in newspapers, periodicals, and the Internet. This Biology in the News (BITN) assignment enables you to focus on the connection between the textbook and the world you live in and to recognize how science and technology influence and contribute to modern culture. 

Select an article from a recent newspaper, periodical, or the Internet which correlates with the content of one or more concepts of instruction covered in the course. Select an article that is written for the general public. Avoid scientific publications.

Choose an article that is:

·       related to content presented in a lesson.

·       of appropriate length, not just an announcement and not ten pages.

·       less than three months old.

·       From current news, not encyclopedic reference.

·       Written for the general public, not a scholarly scientific publication. 

Develop and present a PowerPoint (or other form of content delivery) presentation. This presentation is expected to be in a format and delivered in a manner as though you are presenting to business leadership for their decision and approval. Your presentation will address all 5 chapters of your project. While there is no specific number of slides required, your presentation should last approximately 8-10 minutes, depending on overall class size. The presentation will be given during the live class session.

For this discussion board, we’re doing to delve deeper into ACEs (adverse childhood experiences). The experiences discussed in ACEs are difficult including violence and abuse. I want to give a content warning for this topic. Give yourself space to complete the assignment and let me know if you have any concerns. ACEs are critical to be aware of due to their significant impact on health outcomes and their pervasiveness.

Make sure you’ve read the assigned chapters and review the following resources and answer the questions below:

1) What stands out to you about the ACEs research? 2) How would you describe ACEs to a friend or peer?3) What reactions did you have when you heard about the ACEs findings?4) How does this research impact you as an individual, future public health professional, and/or community member?5) How do these findings relate to anything you have discovered or noticed in your own community?6) What opportunities do you see for using The ACE Study to effect change? What could we be doing to better respond to the ACEs research? (consider public policy, community interventions, as well us as individuals)7) What is one way you as an individual could address ACEs in your community)?8) Linking to what you’ve learned from your text and/or other resources, what do you feel is an effective approach toward addressing ACEs and their impact? (you can address prevention among children and adolescents or you can consider addressing the outcomes of ACEs among adults & what may help attenuate their long-term impact)9) What, if anything, is missing from the conversation about ACEs? What questions do you still have about the ACEs research?

As you answer these questions, make sure to reference your text where relevant.
