Individual Presentation Assignments | Online Homework Help
The purpose of this assignment is to use the skills you have learned throughout all five weeks of the course. You will be able to apply what they have learned to solve a real-world problem that you could use to in your future career.
Create a 5- to a 6-slide presentation that must include:
- One slide on the Introduction
- Introduce your topic and question that you chose in Week 2.
- Why did it interest you? How does it relate to life?
- What should the audience learn from your presentation?
- Three to four slides of your visuals
- Show your tables, scatter plot, other 2 visuals, calculations, and any other evidence to support your conclusion(s) that you created in Week 3.
- Explain what information in the data tables is not needed for your analysis.
- Discuss what you can conclude from the visuals. How do these visuals support your conclusion?
- One slide for a conclusion
- Restate your topic and question and give your answer to the scenario.
- How confident are you that your conclusion is sound?
- What work would need to be done to increase your confidence?
- Discuss what you learned from this project.
Include detailed speaker notes for each slide.

Topic 4: Predicting Teen Communication Preferences. Review the data on communication preferences with teens. Predict how many high-school teens will prefer to use face-to-face communication in 2018.
Scatterplot with Trend line
For your xy scatterplot, make at least one prediction using the trend line equation for some date into the future. How confident are you in this prediction?
The equation of the line of best is y = – 6.0294x+ 12149. From this equation, we can predict the number of teenagers who prefer face to face communication. For example, we can predict that in the year 2018, there would be approximately zero students who will prefer face to face communication face to face. However, the prediction for the year 2018, are a negative value. Since, the number of teenagers cannot be nonnegative, this implies that there will be no teens who will prefer to communicate face to face in the year 2018.
I am very confident in my prediction made using the linear model because the R-squared , or the coefficient of determination is close to one which depicts that model is almost a perfect fit. The R-squared of 0.9471 means that the 94.71% of the response variable (number of teens) variation that is explained by a linear model
The pie chart represent the number of students that prefer to communicate face to face when current data is applied. A percentage is added and represents the total number percentage of student from 2000-2015.
Box and Whisker
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?
From the box and whisker plot data are skewed to the right which you can tell by a long whisker on the right side, then the mean will be greater than the median. This is the case with the data provided to create the box and whisker above. The mean is 44.75 and median 42.5
Calculate the mean of the sample data.
The 44.75 represents the mean from the data provided.
