The table displays the values rounded to the nearest whole number.
Make a scatter plot. How would you describe the correlation between a person’s age and how much he or she spends on a night out?
Does anyone know how to do this?
You are going to make a graph. The x-axis will represent age while the y-axis represents the amount of money spent on a night out. Graph the ordered pairs, making a scatter plot. Once you have all of the points on the graph, answer the question by saying something like "the older someone is, the less money they spend on a night out" but make sure its accurate. (:
The correct answer is:
The correct scatter plot is attached.
There appears to be a negative correlation between a persons age and the amount they spend on a night out.
Age will be the independent variable, along the x-axis, and the cost of a night out will be the dependent variable, along the y-axis.
The ages range from a low of 20 to a high of 45. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 45.
The amounts for a night out range from a low of 38 to a high of 58. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 60.
We then plot each point as a coordinate of (age, amount spent).
Once we get the graph plotted, we see there is a negative trend in the data. As the age increases, the amount spent out decreases.
