The Chart with Paired Data

E

This chart is the scatter diagram.

The correct answer to the question is E. None of these answers.

When paired data, which consists of both dependent and independent variables, are plotted on a chart, it is known as a scatter plot. A scatter plot is a type of plot or graph in which the values of two variables are plotted along two axes, with one variable represented on the x-axis (independent variable) and the other variable represented on the y-axis (dependent variable).

Scatter plots are used to visualize the relationship between two variables and determine if there is any correlation or pattern between them. They are particularly useful in statistical analysis, as they allow analysts to observe the relationship between variables, identify outliers, and determine the strength and direction of the relationship.

Linear regression, mentioned in option A, is a statistical technique used to model and analyze the relationship between a dependent variable and one or more independent variables. While linear regression analysis often involves plotting the data points on a scatter plot, linear regression itself refers to the process of fitting a straight line to the data points to estimate the linear relationship between the variables.

Options B and C, pie and bar charts, are different types of charts used to represent categorical or discrete data, not paired data. A pie chart is a circular chart divided into sectors, where each sector represents a proportion of the whole. It is useful for illustrating the relative sizes or proportions of different categories. A bar chart, on the other hand, uses rectangular bars of varying heights to represent the quantities or values of different categories.

Option D, "Dotted-Swiss," is not a recognized term in statistics or chart types and is therefore not a relevant answer.

Therefore, the correct answer to the question is E. None of these answers because the chart described, where paired data is plotted, is a scatter plot.
