What is scatter diagram?
The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve.
What is purpose of using scatter diagram?
A scatter diagram (Also known as scatter plot, scatter graph, and correlation chart) is a tool for analyzing relationships between two variables for determining how closely the two variables are related. One variable is plotted on the horizontal axis and the other is plotted on the vertical axis.
What is the use of scatter diagram?
A scatter diagram is used to show the relationship between two kinds of data. It could be the relationship between a cause and an effect, between one cause and another, or even between one cause and two others. To understand how scatter diagrams work, consider the following example.
What does the scatter diagram indicate about the relationship between the two variables?
Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation . The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship.
What is used to show the relationship between two variables?
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. Each individual in the data appears as a point on the graph.
Is a graph used to illustrate the relationship between two variables?
A graph shows a relationship between two or more variables. An upward-sloping curve suggests a positive relationship between two variables.
Is a diagram that shows the relation between variables?
A graph is a diagram that shows the relation between variable quantities, typically of two variables, each measured along a pair of axes at right angles.
What type of graphs are used to show change over time?
Line graphs
