Question

The table lists the results from a survey (of questionable accuracy) of adults and how much they spend on a night out.

Answer 1

The correct answer is:

The correct scatter plot is attached.

There appears to be a negative correlation between a person's age and the amount they spend on a night out.

Explanation:

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.

Answer 2

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 it's accurate. (:
