I need help with a signature assignment. I am totally overwhelmed and lost.

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.

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
