Question

step 1 draw a scatter plot. a scatter plot is a graph in the coordinate plane that shows the relationship between two sets of data.
look at the data values to determine the scales for the x - and y - axes.
step 2 plot the ordered pairs (time, number of new views) on the graph.
luciana can use a scatter plot to determine whether there is a relationship between the two data sets.
luciana collects data about the number of entries and the ages of the subscribers who enter the concert giveaway.
the point that represents the data in the fourth column has coordinates (12,9).
convince me! explain how luciana would choose scales for the x - axis and y - axis.
220 4 - 1 construct and interpret scatter plots

Explanation:

Step1: Determine the range of \(x\) - values (Age)

The ages in the data are \(10,11,12,13,14,15\). The range of \(x\) - values (age) is from \(10\) to \(15\). So, for the \(x\) - axis (age), we can start the scale at \(10\) and have an interval of \(1\) (since the values are consecutive integers in this range).

Step2: Determine the range of \(y\) - values (Number of Entries)

The number of entries are \(8,8,9,9,10,10\). The range of \(y\) - values (number of entries) is from \(8\) to \(10\). So, for the \(y\) - axis (number of entries), we can start the scale at \(8\) and have an interval of \(1\).

Answer:

For the \(x\) - axis (age): start at \(10\) with an interval of \(1\). For the \(y\) - axis (number of entries): start at \(8\) with an interval of \(1\).
