Question

Alice wants to create a visualization of some data she has collected. She wants to show the progression of fuel prices from two different countries over a period of three years. What is the BEST representation for her to use?A. a pie chartB. a scatter plotC. a decision treeD. a line graph

Answer 1

The first Option given is

A) PIE CHART:

A pie chart is a circle that is divided into areas, or slices. Each slice represents the count or percentage of the observations of a level for the variable. Pie charts are often used in business.

B) Scatter plot:

A scatter plot (also called a scatterplot, scatter graph, scatter chart, scattergram, or scatter diagram) is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.

C) Decision tree:

A decision tree is a decision support tool that uses a tree-like model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm that only contains conditional control statements.

D) Line graph:

A line graph is a type of chart used to show information that changes over time. We plot line graphs using several points connected by straight lines. We also call it a line chart. The line graph comprises of two axes known as 'x' axis and 'y' axis. The horizontal axis is known as the x-axis.

Hence,

The final answer is

`\Rightarrow line\text{ }graph`

OPTION D is the right answer
