Describing A Scatter Plot. With several data points graphed a visual distribution of the data can be seen. Now the question comes for everyone. Scatter plots are used to observe relationships between variables. For example the scatterplot of latitude and January temperatures had negative direction as the greater the latitude the colder the temperature.
Now the question comes for everyone. Complete the scatter plot in Figure 9-2 and underneath the scatter plot describe the type of relationship if any that appears to exist between price and quantity. A scatter plot aka scatter chart scatter graph uses dots to represent values for two different numeric variables. The scatter diagram graphs numerical data pairs with one variable on each axis show their relationship. Things to look for. In this lesson students learn that a scatter plot is a graph in which the data is plotted as points on a coordinate grid and note that a best-fit line can be drawn to determine the trend in the data.
Things to look for.
The position of each dot on the horizontal and vertical axis indicates values for an individual data point. A quick description of the association in a scatterplot should always include a description of the form direction and strength of the association along with the presence of any outliers. These scatter plots were created by multiplying the x-coordinate by 3 then adding a random number between two values to get the y-coordinate. Complete the scatter plot in Figure 9-2 and underneath the scatter plot describe the type of relationship if any that appears to exist between price and quantity. In this lesson students learn that a scatter plot is a graph in which the data is plotted as points on a coordinate grid and note that a best-fit line can be drawn to determine the trend in the data. Example of direction in scatterplots.
