What is a scatter plot?

Short Answer

Expert verified
A scatter plot is a mathematical diagram using Cartesian coordinates to display values for two variables for a set of data. It's used to display and compare the relationship between two sets of data. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line or curve.

Step by step solution

01

Understanding the terminologies

A scatter plot or scatter graph is a type of plot or mathematical diagram. It uses Cartesian coordinates to display values for typically two variables for a set of data.
02

Characteristics of a Scatter Graph

The data is displayed as a collection of points, each having the value of one variable as its position on the horizontal axis and the value of the other variable determining the position on the vertical axis.
03

Usage of a Scatter Plot

This type of graph is used to display and compare the relationship, if any, between two sets of data. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line or curve.

Most popular questions from this chapter

a. Create a scatter plot for the data in each table. b. Use the shape of the scatter plot to determine if the data are best modeled by a linear function, an exponential function, a logarithmic function, or a quadratic function. $$ \begin{array}{|c|c|} \hline \boldsymbol{x} & \boldsymbol{y} \\ \hline 0 & -4 \\ \hline 1 & -1 \\ \hline 2 & 0 \\ \hline 3 & -1 \\ \hline 4 & -4 \\ \hline \end{array} $$

a. Determine if the parabola whose equation is given opens upward or downward. b. Find the vertex. c. Find the \(x\)-intercepts. d. Find the \(y\)-intercept. e. Use (a)-(d) to graph the quadratic function. \(y=-x^{2}+2 x+3\)

Graph the solution set of each system of inequalities. \(\left\\{\begin{array}{l}x+y \leq 4 \\ y \geq 2 x-4\end{array}\right.\)

In Exercises 23-24, use a table of coordinates to graph each exponential function. Begin by selecting \(-2,-1,0,1\), and 2 for \(x\). Based on your graph, describe the shape of a scatter plot that can be modeled by \(f(x)=b^{x}, 0

Graph each linear inequality. \(y>-2\)
