How do you define a scatter plot?
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
What is a scatter plot and what is it used for?
Scatter plots are used to plot data points on a horizontal and a vertical axis in the attempt to show how much one variable is affected by another. Each row in the data table is represented by a marker whose position depends on its values in the columns set on the X and Y axes.
What is a scatter plot Kids definition?
scatter diagram, scatter plot. • a scatter plot is a diagram where points. are plotted to show the relationship (correlation) between two variables.
What are the variables in a scatter plot?
A scatter plot is a plot of the values of Y versus the corresponding values of X: Vertical axis: variable Y–usually the response variable. Horizontal axis: variable X–usually some variable we suspect may ber related to the response.
What is scatter plot in Six Sigma?
Scatter plots are a way of visualizing the relationship; by plotting the data points you get a scattering of points on a graph. Scatter Diagrams are used to show the “cause-and-effect” relationship between two kinds of data, and to provide more useful information about a production process.
What is the correlation of a scatter plot?
The relationship between two variables is called correlation. A scatter plot usually consists of a large body of data. 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 scatter diagram with example?

What is a scatter plot in statistics?
A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.
What type of data do you need to make a scatter plot?
Required data. A scatter plot displays data for a set of variables (columns in a table), where each row of the table is represented by a point in the scatter plot. The variables can be both categorical, such as Language in the table below, and numeric, such as the various scores assigned to countries in the table below.
What two variables does a scatter plot have?
When the two variables in a scatter plot are geographical coordinates – latitude and longitude – we can overlay the points on a map to get a scatter map (aka dot map). This can be convenient when the geographic context is useful for drawing particular insights and can be combined with other third-variable encodings like point size and color.
Can you show some examples of scatter plots?
Example: The local ice cream shop keeps track of how much ice cream they sell versus the noon temperature on that day.
How do you interpret scatter plots?
You interpret a scatterplot by looking for trends in the data as you go from left to right: If the data show an uphill pattern as you move from left to right, this indicates a positive relationship between X and Y. As the X-values increase (move right), the Y-values tend to increase (move up).
