Which one of the following plot is used to plot values of two variables?PieCharthistogramScatterPlotlinegraph

Step 1: Break Down the Problem

We need to identify which type of plot is suitable for visualizing the relationship between two variables from the given options.

Step 2: Relevant Concepts

• Pie Chart: Used to show proportions of a whole; not suitable for two variables.
• Histogram: Displays the distribution of a single variable; does not relate to two.
• Scatter Plot: Used to show the relationship or correlation between two numeric variables.
• Line Graph: Typically used to show trends over time, often with one variable being dependent on another.

Step 3: Analysis and Detail

Among the options listed:

1. Pie Chart clearly does not fit our requirement as it represents one categorical variable.
2. Histogram also does not apply as it assesses one variable's frequency distribution.
3. Scatter Plot is designed specifically to depict the correlation between two quantitative variables, plotting them along two axes.
4. Line Graph can represent two variables but is more focused on trends over time rather than the direct relationship between two independent variables.

Step 4: Verify and Summarize

After considering all options, the Scatter Plot is the correct choice for plotting values of two variables, given its specific purpose of illustrating the relationship between them.

Final Answer

The plot used to plot values of two variables is a Scatter Plot.
