What is the purpose of a 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.
The better the correlation, the tighter the points will hug the line..
How do you interpret a scatter diagram?
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).
How do you describe a scatter diagram?
Overall Pattern: To describe a scatterplot, state the direction (positive or negative), form (is it linear?), how strong the relationship appears (how large is the scatter), and identify any outliers. – Changes in scale can drastically effect the picture presented.
What is a scatter plot Quizizz?
The scatter plot shows the relationship between the number of chapters and the total number of pages for several books. Use the trend line to predict how many chapters would be in a book with 180 pages. … You are analyzing a scatter plot that has a negative correlation.
What is the purpose of a scatter plot quizlet?
Scatter plots depict the results of gathering data on two variables; the line of best fit shows whether these two variables appear to be correlated. a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
What is scatter diagram with example?
A Scatter (XY) Plot has points that show the relationship between two sets of data. In this example, each dot shows one person’s weight versus their height. (The data is plotted on the graph as “Cartesian (x,y) Coordinates”)
What is a scatter plot and how does it help us?
A scatterplot is a graph of paired (x, y) quantitative data. It provides a visual image of the data plotted as points, which helps show any patterns in the data. … It provides an organized display of the data, which helps show patterns in the data.
What does a cluster tell you about the data on a scatter plot?
sometimes the points may form two or more distinct clouds of points. These clouds are called clusters. Investigating these clusters may tell you something useful about the data. general pattern or that is far away from the other points in the scatter plot.
How is a scatter plot used to represent correlations 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.
How can you tell if a scatter plot is negative or positive?
A scatter plot can show a positive relationship, a negative relationship, or no relationship. If the points on the scatter plot seem to form a line that slants up from left to right, there is a positive relationship or positive correlation between the variables.
