The purpose of this assignment is to gain experience creating visuals using the data for the topic you selected in Week 2. Use statistical reasoning and mathematical modeling to show central tendency and two-variable analyses, including regression with equation and R2 value.
Watch How to Create Trendlines and Scatterplots in Excel®.
Watch Lynda.com® Video: Adding Trendlines to Charts. This video can be accessed under Student Materials on the right side of the screen.
Watch Lynda.com® Videos: Creating Pie Charts, Histograms, & Box-and-Whisker Plots. This video can be accessed under Student Materials on the right side of the screen.
Create at least three visuals.
One visual must be a scatterplot with trend line, equation and R2 value.
Two of the remaining required visuals can be a histogram, box and whisker plot, or pie chart.
Please note that the data sets include data that will not be needed to create your visuals. Quantitative reasoning requires critical thinking to decide what data is necessary.
Create a Word document that includes your three visuals and the following items:
Title of your project and the scenario you are addressing
Brief description of each visual (15 to 50 words)
Consider including the following for each visual when applicable:
A chart title that is appropriate for the data
A descriptive x-axis label
A descriptive y-axis label
For your xy scatterplot, make at least one prediction using the trendline equation for some date into the future. How confident are you in this prediction? State your prediction and provide justification (50 to 150 words).
If you created a box and whisker plot, describe the central tendency of the values. What does this tell you about the data and about your project?
Calculate the mean of the sample data.
ASSIGNMENT #2 POWERPOINT PRESENTATION
The purpose of this assignment is to use skills you have learned throughout all five weeks of the course. You will apply what you have learned to solve a real-world scenario that you could encounter in your future career.
Create a 5- to 7-slide Microsoft® PowerPoint® presentation including:
Introduction (approximately 1 minute and 1 slide)
Which topic and scenario did you choose?
Why did it interest you?
Visuals/Evidence (approximately 4 to 5 minutes and 3-4 slides)
Show your data table, scatterplot, other two visuals, calculations, and any other evidence to support your conclusion.
Explain what information in the data tables is not needed for your analysis. Explain why the unused information is not needed.
Discuss why you selected each visual and what you can conclude from the visuals.
Conclusion (approximately 1 minute and 1-2 slides)
Restate your topic and scenario and give your conclusion.
Discuss how your topic relates to a real-world scenario.
Explain how confident you are that your conclusion is sound.
Explain what work would need to be done to increase your confidence in your conclusion.
Discuss what you learned from this project.
Include detailed speaker notes for each slide.
