what type of graph is used to show the relationship between two variables?
240186
Scatter plots are similar to line graphs in that they use horizontal and vertical axes to plot data points. However, they have a very specific purpose. Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation .

Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical), graphically denoted as (x,y). Each axis represents a different data type, and the points at which they intersect is (0,0). The x-axis is the independent axis as its values are not dependent on anything measured.

The most commonly used techniques for investigating the relationship between two quantitative variables are correlation and linear regression. Correlation quantifies the strength of the linear relationship between a pair of variables, whereas regression expresses the relationship in the form of an equation.

Most position vs. time graphs have time as the independent variable and position as the dependent variable. Information about the motion of an object can be shown by the graph's slope. This particular information is known as the velocity, a vector quantatity detailing an object's speed and direction.

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

A scatter plot is a graph of points that show the relationship between two different pieces of data, while a line graph is a graph that shows information via a connected line.

Scatter Plot Chart A scatter plot or scattergram chart will show the relationship between two different variables or it can reveal the distribution trends. It should be used when there are many different data points, and you want to highlight similarities in the data set.

The graph of a non-proportional linear relationship is a line that does not cross through the origin, whereas the graph of a proportional linear relationship is a line that does cross through the origin. ... Connect the two points in a straight line.

The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

a Bar Graph. Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

The relationship between the independent and dependent variables is said to be "explained away" by the control variable. Bivariate tables that display the relationship between the independent and dependent variables while controlling for a third variable.

Such a graphical representation is called a scatterplot. A scatterplot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis.

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.
