Create at least three visuals.

  • One visual must be a scatter plot with trend line, equation, R2 value, and prediction value.
  • Two of the remaining required visuals can be of the following format: histogram, box and whisker plot, or pie chart.
  • Please note that the data set that you chose in Week 2 includes data that will not be needed to create your visuals. Quantitative reasoning requires critical thinking to decide what data is necessary.

Create a Microsoft® 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 scatter plot, make at least one prediction using the trend line equation for a date in 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.
