What does a scatter plot show?
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.
What type of association is shown by the scatter plot?
A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.
Which describes the correlation shown in the scatterplot?
Terms in this set (10) Which describes the correlation shown in the scatterplot? There is a positive linear correlation.
What is the purpose of a scatter plot quizlet?
a graph with points plotted to show a possible relationship between two sets of data.
What type of association is shown by the scatter plot quizlet?
A scatter plot is a graph of plotted points that shows a relationship between two sets of quantitative data (referred to as bivariate data).
How do you infer a scatter plot?
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).
Which statement is correct when a scatterplot is constructed?
The correct statement that is used when a scatter plot is constructed is: The independent variable is the input variable and should be represented by the x-axis.
What may be revealed from a scatterplot quizlet?
A scatterplot shows the relationship between two quantitative variables measured on 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 in the graph.
When data is displayed with a scatter plot it is often useful to attempt to represent that data with the equation of a straight line what is this line called and what is its purpose?
Mentor: A line of best fit is often useful to attempt to represent data with the equation of a straight line in order to predict values that may not be displayed on the plot. The line of best fit is determined by the correlation between the two variables on a scatter plot.
What is the purpose of a scatter plot diagram quizlet?
How do you describe a scatter plot matrix?
A scatter plot matrix is a grid (or matrix) of scatter plots used to visualize bivariate relationships between combinations of variables. Each scatter plot in the matrix visualizes the relationship between a pair of variables, allowing many relationships to be explored in one chart.
When to use scatter plots?
Scatter plots are used when you want to show the relationship between two variables. Scatter plots are sometimes called correlation plots because they show how two variables are correlated.
What does correlation mean in scatter plot?
Scatter plot Correlation We know that the correlation is a statistical measure of the relationship between the two variables’ relative movements. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the closer the points will touch the line.
What is a connected scatter plot in research?
Connected scatter plot. If the third variable we want to add to a scatter plot indicates timestamps, then one chart type we could choose is the connected scatter plot. Rather than modify the form of the points to indicate date, we use line segments to connect observations in order.
What is the independent variable on a scatter plot called?
The independent variable or attribute is plotted on the X-axis, while the dependent variable is plotted on the Y-axis. These plots are often called scatter graphs or scatter diagrams. A scatter plot is also called a scatter chart, scattergram, or scatter plot, XY graph.
