Question
Use the given data to answer the questions and construct the scatter plots.
Pathfinder Character Level vs. Total Experience Points
a) Which variable should be the independent variable (x-axis) and which should be the dependent variable (y-axis)?
b) What scale and interval should you use for the x-axis?
c) Construct the scatter plot.
Hint:
A scatter plot is used to plot points on the horizontal and a vertical axis in the attempt to show how much one variable is affected by another. The independent variable is the cause and is independent of any other variables. The dependent variable is the effect and depends on the independent variable.
We are asked to find the dependent and independent variable, scale and interval for the x- axis and the scatter plot for the given table.
The correct answer is: We are asked to find the dependent and independent variable, scale and interval for the x- axis and the scatter plot for the given table.
Step 1 of 4:
Analyzing the table, it is clear that the total experience points depend on the level you are in. The higher the level, the more points you get.
So, the level is the independent variable and the experience point (XP) is the depend variable.
Step 2 of 4:
Here, we consider an interval of one to twenty (1 to 20).
The scale for the axis would be two units.
Step 3 of 4:
The coordinate points corresponding to the table of values are:
(2,15),(3,35),(6,150),(9,500),(10,710),(11,1050),(14,2950),(15,4250),(17,8500),(20,24000)
Step 4 of 4:
Plot the points to get the required scatter graph.
The interval is the relation between the units you are using and their representation on the graph or the distance between marks. You choose intervals based on the range of the values in the data set.
