Question

# Use the given data to answer the questions and construct the scatter plots.Age vs. Weekly Allowancea) 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 y-axis?c) Construct the scatter plot.

Hint:

## The correct answer is: A graph can be plotted using different scales and intervals. Graphs obtained corresponding to different scales and intervals are also correct. Keep in mind that the points are located correctly.

### Step 1 of 3:Here you get the allowance based on your age. The amount you receive is solely based on your age. The older you are, the higher the allowance. So, age is definitely the independent variable and allowance is the dependent variable.Step 2 of 3:The interval we could use here is 0 to 40.The scale corresponding to the interval could be one interval =one unit or one interval =two unit. Both can be used according to your convenience.Step 3 of 3:The coordinate points for the graph would be: (12,0),(12,5),(13,5),(13,8),(14,10),(14,15),(15,20),(15,20),(16,25),(16,30).Plotting them on the graph, we get the required scatter plot:
