Stats in SPSS With Dr. Ami Gates
Open SPSS (for help see the attached file, SPSS Installation Instructions) and complete the following:
Obtain an output (as in the tutorials) with the following values
highlighted and upload it into LoudCloud:
Determine the statistics for each gender as follows:
Frequency Counts, Mean, Standard Deviation, Minimum, and Maximum
Graphing and Descriptive Stats in SPSS: Create a bar graph with gender
(axis X) and height (axis Y)
Upload the output into LC.
Data set:
Men: 74, 71, 75, 62
Female: 62, 68, 61, 71, 68, 80
In Module 02 you chose a disease that you would like to know more about. Throughout the term you have been gathering information on that topic. Now it’s time to put it all together into your annotated bibliography. Your submission should include the following:
The subject i choose was asthma
Brief Overview of Activity: Locate and analyze two news reports of recent astronomical discoveries.
Required Items: The internet and/or periodicals such as (for example) The Washington Post or Sky and Telescope
The daily news is not just sports and politics. It includes science too! For this simple activity all you need to do is find two articles related to astronomy (either online or in hard copy), summarize and analyze them. The topics can be anything of your choosing so long as they are relevant to the course material. Examples could be a new telescope that has recently come online, the discovery of a new exoplanet, etc.; the idea is for you to find and write up something you are interested in! The writeup should be roughly one page long (double-spaced); the first half should be a summary of what was discovered, and the second should be your analysis of it–did it make sense? Was it well-written? Did it tie into things we’ve discussed in class? What are some of the ramifications, etc.? Include the complete citation of the original article (hyperlinked if it is from the internet). Make sure your sources are reputable ones, whether online or not; if you have any concerns about whether that’s the case or not, please simply contact me and I can give you my opinion.
HR Diagram Activity (30 points)
Brief Overview of Activity: Use an HR diagram to learn about the differences between the stars in our stellar neighborhood and the brightest stars in the sky.
Required Items: this HR diagram, red & black ink pens.
Procedure:
On the HR diagram, plot each star from the “Brightest Stars Group” in black ink and then plot each star from the “Nearest Stars Group” in red ink.
Data for both groups of stars can be found below.
Describe any differences between the two groups of stars – such as their location on the diagram, color, mass, and the types of stars in each group.
Which of the two groups of stars is most representative of the vast majority stars in the universe?

Radioactive Dating Activity (due at Stage 2) (30 points)
Brief Overview of Activity: Radioactive decay is one of the sources of the heat that drive the Earth’s geologic activity. Radioactive decay also allows us to date rocks and determine the age of the Earth and other solar system bodies.
Required Items: 36 coins, a calculator, pencil & paper.
Procedure:
In this activity you will simulate the radioactive decay of 36 atoms of a rare isotope of uranium, U-235. Uranium-235 has a half-life of 700 million years. Gather 36 coins and arrange them in a 6 x 6 grid with all of the coins facing heads up.
Flip each coin into the air and then place it back in its original location on the grid. This represents the passage of 1 half-life (700 million years for this example). The coins that came up heads represent atoms that have not yet decayed; the coins that came up tails represent atoms that have decayed. Record the number of heads below.
Next flip each one of the remaining heads-up coins once and place it back in its original location. 1.4 billion years have now passed by (2 x 700 million). Record the number of remaining heads below. Repeat this process until all coins are tails up.
_______ Original number of U-235 atoms
_______ Remaining number of U-235 atoms after 1st flip
_______ Remaining number of U-235 atoms after 2nd flip
Add additional lines as needed.
Questions:
How many half-lives did it take for all of the atoms to decay?
How many years does that equate to?
Do you think everyone in class will get the same answer? Why?
