Question

Ira is the middle school basketball statistician. She tracks the number of minutes a player plays and the number of fouls the player makes. Her data are shown in the scatter plots. Is there an association between the number of minutes played and the number of fouls made?

hintHint:

A scatter plot shows the association between two variables.  If the points are clustered around the association is strong or else its weak. If they are far from each other, it has no association.
We are asked to find if there exists an association between the number of minutes played and the number of fouls made.

The correct answer is: We are asked to find if there exists an association between the number of minutes played and the number of fouls made.


    ANSWER:
    Step 1 of 1:
    Analyzing the graph, we can clearly see that a trend line cannot be drawn to approximate the trend. Moreover, the points are scattered all around the graph, describing the inexistence of a relationship among the data set.
    Thus, we can say that there exists a weak or no association for the given set of data.
     

    If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

    Given five noncollinear points, make a conjecture about the number of ways to connect different pairs of points.

    Number of connections for 3 noncollinear points = 3
    Number of connections for 4 noncollinear points = 6
    Next from the figure, we get number of connections for 5 noncollinear points = 10
    So the sequence is 3, 6, 10

    Given an example of a non-linear function in table form.
    X          
    Y          

    We know that the graph of a non linear function is not a straight line.
    So, we can plot the above ordered pairs to verify that the graph of the above points is not a straight line and hence not a linear function.

    Sketch an example of a linear function in graph form.

    We can take any straight line in the xy plane and derive its equation in the above method; we will get a linear function. We can check this by calculating the slope between all the points. If the slope is constant everywhere, then it is linear.

    Determine whether the following functions are linear or non-linear and explain how you know.
    Y equals 2 to the power of x plus 3

    There are other ways to determine if a given equation is linear or not. If an equation can be written in the form y = ax + b, where a and b are constants, then the function is linear. Another way to check if an equation is linear is by checking the highest degree of a term in the equation. If the highest degree of any term in the equation is 1, then the equation is linear, and if the degree of any term is greater than 1, then the equation is non-linear.
