Q1 Calculate mean yearly returns for each stock.

Hint: See the code in 4.3.1 Bar chart (on summary statistics).

Q2 Plot mean yearly returns using bar charts.

Hint: See the code in 4.3.1 Bar chart (on summary statistics).

plot mean salaries

Q3 Label the bars with mean yearly returns.

Hint: See the code in 4.3.1 Bar chart (on summary statistics).

Q4 Plot the distribution of yearly returns by stock using kernel density plots.

Hint: See the code in 4.3.2 Grouped kernel density plots.

Q5 Which of the three stocks has highest chance of losing big when things go wrong? Discuss your reason.

Hint: Google how to interpret density plots.

IBM has the highest chance of loosing big when things go wrong. Because it has the highest return it means it will have the highest loss.

Q6 Plot the distribution of yearly returns by stock using boxplots.

Hint: See the code in 4.3.3 Box plots.

Q7 If you were a risk-loving investor (defined as one chasing after the greatest returns even at the risk of losing big), which of the three stocks would you choose? Discuss your reason.

I would choose to use IBM for many reasons. One, IBM is the highest of returns.Seeing that the return is the highest but not by much, there would not be a crazy difference if I went with another stock. Compared to Apple of Microsoft there is not much risk taken. Overall, I would be taking the the highest risk and highest return.

Q8 Hide the messages, but display the code and their results from the webpage.

Hint: Use message, echo and results in the global chunk options. Refer to the RMarkdown Reference Guide.

Q9 Display the title and your name correctly at the top of the webpage.

Q10 Use the correct slug.
