Question $4-$ Adele

One general rating system for music$/$movies is to rate the art from $1$ stars to $5$ stars; the more stars,

the better. Sometimes there are half stars given as well.

Consider now the following data set $($call it Adele$),$ which tracks reviews of singer$-$songwriter Adele's

last two studio albums, $25(2015)$ and $30(2021)$ by major music critic outlets. Data obtained from

Metacritic. Where necessary, review scores have been translated from $1$ to $5$ stars using the following

scale:

$0-10$: $0\mathrm{.}5$ stars $11-20$: $1$ stars $21-30$: $1\mathrm{.}5$ stars $31-40$: $2$ stars $41-50$: $2\mathrm{.}5$ stars $51-60$:

$3$ stars $61-70$: $3\mathrm{.}5$ stars $71-80$: $4$ stars $81-90$: $4\mathrm{.}5$ stars $91-100$:$5$ stars

a$.$ With the column names given in the data set above, write code with ggplot$()$ that would

visualize the reviews of the two albums using a two$-$variable plot. Make sure to label your

axes and give the plot a title. What is the geometry and aesthetic mapping$($s$)$ of the plot you

chose?

b$.$ Then sketch the plot out as you have coded it$,$ and plot the points in the data set on the

graph.

c$.$ Did you run into any issues plotting your points? If so$,$ what were they?

d$.$ Now write code with ggplot$()$ that would visualize the reviews of the two albums in such a

way that would resolve the issues you should have identified in part $c.$
