Which type of graph do you use to show the relationship between two things?

Which type of graph do you use to show the relationship between two things?

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose ( x , y ) (x, y) (x,y)left parenthesis, x, comma, y, right parenthesis coordinates relates to its values for the two variables.

Which of the graphs show changes in quantities presented?

Area graphs show a change in one or more quantities over a certain period of time. They often help when displaying trends and patterns.

What is the best graph to compare data?

. . . a Line graph. Line graphs can also be used to compare changes over the same period of time for more than one group.

How do you choose the best graph?

If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart. If you want to show trends and patterns in your data, use a line chart, bar chart, or scatter plot.

Which graphing relationship is best for predictions?

With a line graph, it is fairly easy to make predictions because line graphs show changes over a period of time. You can look at past performance in a line graph and make a prediction about future performance.

How are graphs used to relate two quantities?

• Graphs can be used to visually represent the relationship between two variable quantities as they each change. • A graph is the most understandable way of showing how one variable changes with respect to another variable. • Graphs can show changes in speed, altitude, distance, volume, time, and other variable quantities.

How is a line graph used to find a relationship?

line graphs Many investigations in science are concerned with finding relationships between continuous variables. After collecting a set of data, the data points for two variables can be plotted on a graph, and then a line drawn that best expresses the apparent relationship suggested by the data. This is called a line of best fit.

How are two quantities related in real life?

Many real life applications of mathematics investigate the relationship between two quantities. For example: the value of a Computer is related to its age the price of a watermelon is related to its weight the time taken for a person to walk to school is related to the walking distance.

Are there any graphs that always go up or down?

So far, all of the graphs discussed have had a line that either always goes up or always goes down (the technical term for this is monotonic). Other relationships are more complex, with lines than can go up and down (called non-monotonic). The last two examples are included to illustrate this. Figure 7.8a could represent the height
