You will be working on the Semester Project throughout the term in parts as Project Part Assignments. Additional information can be found on the Semester Project Information page. You will get feedback from your instructor on the parts of the project in the Project Parts as listed. Use that feedback to improve that portion of the project.
Project Part 1: Systematic Sample of your chosen Data Set
1) Choose 1 Data Set from the Data Sets for Project Parts and the Semester Project page.
2) Create a Systematic Sample with 35 values.
Use your birth month as the starting value in Row 1, then use your birthdate as your nth value. An example with additional details is the Data Sets.
3) Write at least 2 quality sentences explaining which Data Set you used, what your starting number was, your nth value, and how you did it, so that any other person would be able to obtain the same results.
4) List your 35 values in the order they were collected.
When working on each part of the Semester Project the Best Practice is to type the information onto the appropriate slide of the Template Download Template, remove the directions, and then copy and paste your work and results into the text submission area of the assignment.
You may submit the project part as a text submission, Word Document, or PowerPoint Slide from the Template (only that slide!) Do not submit your work as an embedded image in one of those files. Images cannot be accepted for these assignments. (File Types allowed: .doc,.docx, ppt., pptx)

Please read the questions carefully. You will be required to use Microsoft Excel to complete the assignments. The grades will be based on your ability to calculate the correct answers, the methodology employed, and the interpretation of the results. 

Open the Heart Rate Data Set in Excel
Using the classification of variables from the Unit 1 assignment as
qualitative, quantitative discrete, or quantitative continuous, match
each of the 3 variables to the most appropriate graph type. (For
example, qualitative data can best be displayed with a pie chart or bar
graph; continuous numerical data can best be displayed using a
histogram)
Use the graphing functions in Excel to create an appropriate graph
of the data for each variable. Remember to properly label and title your
graphs to identify what the graph is about clearly.

In this lesson’s assignment, you will complete a problem set in which you address levels of data and types of variables. Answers to the problems must be complete and written in formal narrative language. In addition, you will write a short essay related to data privacy. You will also explore the different types of graphs used to visualize data. Results from both Excel and SPSS should be copied and pasted into a Word document for submission.
Explain the concept of a random variable.  Explain what it means to say, “Variables must vary.”  Why is the concept of variables important for learning statistics?
List and define the four levels of measurement (using examples) discussed in this lesson’s introduction and resources. In your opinion, which one or more is the most appropriate for statistical analysis? Explain. 
Compare and contrast the characteristics of continuous and discrete variables. What is a common challenge of trying to calculate statistics using discrete variables?
Identify example variables from your professional and personal life at each level of measurement.  Explain why you selected the level you did for each, relying on this lesson’s resources for support.
Identify at least 4 (two of each) discrete and continuous variables from your own professional or personal life and explain why you selected the category you did for each, relying on this lesson’s resources for support.
Use the provided datasets for building one of each of the four chart types below.  For each chart, select a variable from the provided dataset with a measurement level that is best visualized by that chart type. Use APA style to label each chart. Each graph must contain a narrative description of what it represents and an interpretation of the image.  Use this narrative and the graph to tell a story with your data.

I have uploaded the Rubric/Guidelines, Module Overview, Reading and Resources, and chapters from the textbook.

You have been recently hired as a junior analyst by D.M. Pan Real Estate Company. The sales team has tasked you with preparing a report that examines the relationship between the selling price of properties and their size in square feet. You have been provided with a Real Estate Data Spreadsheet spreadsheet that includes properties sold nationwide in recent years. The team has asked you to select a region, complete an initial analysis, and provide the report to the team.
Note: In the report you prepare for the sales team, the response variable (y) should be the listing price and the predictor variable (x) should be the square feet.
Specifically you must address the following rubric criteria, using the Module Two Assignment Template:
Generate a Representative Sample of the Data
Select a region and generate a simple random sample of 30 from the data.
Report the mean, median, and standard deviation of the listing price and the square foot variables.
Analyze Your Sample
Discuss how the regional sample created is or is not reflective of the national market.
Compare and contrast your sample with the population using the National Summary Statistics and Graphs Real Estate Data PDF document.
Explain how you have made sure that the sample is random.
Explain your methods to get a truly random sample.
Generate Scatterplot
Create a scatterplot of the x and y variables noted above. Include a trend line and the regression equation. Label the axes.
Observe patterns
Answer the following questions based on the scatterplot:
Define x and y. Which variable is useful for making predictions?
Is there an association between x and y? Describe the association you see in the scatter plot.
What do you see as the shape (linear or nonlinear)?
If you had a 1,800 square foot house, based on the regression equation in the graph, what price would you choose to list at?
Do you see any potential outliers in the scatterplot?
Why do you think the outliers appeared in the scatterplot you generated?
What do they represent?

In Unit 3 you were introduced to correlations and the relationship that exists between variables. We deal with and hear about correlations frequently in our everyday lives (Ex: The bus is running late, there must be a lot of traffic. My computer’s internet is running slow, there must be a lot of people on the Wi-Fi. Gas prices are going up, must be Bidens fault, etc.). The interesting part about these “correlations” is that they are all not necessarily true or related, we can sometimes make ourselves believe they are. For this discussion I want you to search the internet for a common correlation we see in society now a day. You can use social media, google, articles YouTube, etc., just make sure they are reliable and appropriate for class. Without doing further research explain how you think this correlation can be tested. What two variables would we have to measure in order to show a relationship for the topic you shared. Of course, we learned that correlation does not equal causation. So the goal of this exercise is to put that into practice and learn about what common correlations are out there that in fact could be misconceptions.

You
are to write a short paper addressing one inaccurate statement that many people
might think is true (e.g., happier employees are more productive, vaccines
cause autism, boys are smarter than girls; please do not use these in your
paper) by means of finding and reporting 3-5 statistics from peer-reviewed journal
articles that disconfirm the claim you picked.

DB: Module 4 Practice Tests Chapters 8 & 9: Post your Math questions from chapter 8 & 9 on

You are required to post (at least) one question and its solution either from Chapters 8 & 9 Practice Tests posted under the modules, or any source of your choice (per grading policy in the syllabus). You must read all the posts and make sure not to duplicate any questions; similar questions are acceptable.
Read all the posts: questions and solutions posted by others first, and pick a different question to post (No duplication is allowed). A question with One-word solution, One-line solution, or Definition is not acceptable and results in ZERO Points for the post . (10 points)Write the question number and copy down the question
Show all steps using the math equation editor or embed an image solution as explained below.
Find a similar problem online, or on YouTube, or Khan Academy and post the link. (5 points)
Comment on (Explain) at least one classmate question that is either solved or is found online and posted by watching it carefully in its entirety. Explain about what the question addressed and what you learned from it and outline a few steps you learned as a result; a compliment is nice but is not a comment. To receive credit for this part, write the name of your classmate. (5 points)
Example of a Student Post (Made up example):
1. Question 15: Find the mean, median, mode, and range for the following Population list: 13, 18, 13, 14, 13, 16, 14, 21, 13
Solution: 𝜇=∑𝑥𝑁=13+18+13+14+13+16+14+21+139=9
The median is the middle value, so rank the data first: 13, 13, 13, 13, 14, 14, 16, 18, 21
Population size: N = 9, so the middle value will be the (9 + 1) ÷ 2 = 10 ÷ 2 = 5th number:
13, 13, 13, 13, 14, 14, 16, 18, 21 ⟹𝑀𝑒𝑑𝑖𝑎𝑛=14
The mode is the number that is repeated more often than any other: ⟹𝑀𝑜𝑑𝑒=13
𝑅𝑎𝑛𝑔𝑒𝑅=𝑀𝑎𝑥−𝑀𝑖𝑛=21−13=8

3. Comment on question by John Doe’s YouTube post: This post was about finding the Z Scores; they represent number of standard deviations away from the mean. A positive Z-score indicates a score which is above the average score in class. A negative Z-score indicates a score which is below the average score in class. A zero Z-score indicates a score equal to the average score in class.
https://www.youtube.com/watch?v=1yYCyAwg-7gLinks to an external site.
Grades: A positive Z Score represents a grade greater than the mean (average) grade in class. A negative Z Score represents a grade smaller than the mean (average) grade in class. A zero Z Score represents a grade that is equal to the mean (average) grade in class.
