A discrete graph is a type of graph where only individual data points are plotted, and there are no connections or lines between them. It is used to represent data that cannot be connected or interpolated. Each data point is usually represented by a dot or a symbol on the graph.
Discrete graphs are typically used to represent data that is measured at specific intervals or in distinct categories. For example, the number of books read by a student each month or the number of students in each grade level would be represented with a discrete graph.
To create a discrete graph, you should start by labeling the x-axis with the categories or intervals being measured and the y-axis with the corresponding values. Then, you can plot each data point on the graph using dots or symbols. Make sure to label each point with its corresponding value.
For example, let’s say we want to create a discrete graph to represent the number of hours a student spends studying each week:
Week 1: 5 hours
Week 2: 4 hours
Week 3: 6 hours
Week 4: 3 hours
First, label the x-axis with the weeks (Week 1, Week 2, Week 3, Week 4) and the y-axis with the number of hours. Then, plot each data point on the graph:
– Week 1: plot a dot or symbol at the coordinates (Week 1, 5).
– Week 2: plot a dot or symbol at the coordinates (Week 2, 4).
– Week 3: plot a dot or symbol at the coordinates (Week 3, 6).
– Week 4: plot a dot or symbol at the coordinates (Week 4, 3).
After plotting all the data points, you can connect them with straight lines if you want, to make the graph easier to read. However, it’s important to note that, in a discrete graph, the lines do not represent continuous values or connections between the data points. They are simply used to visually guide the reader.
Overall, a discrete graph is a helpful tool for representing data that is not continuous or connected. It allows us to focus on individual data points and easily compare their values.
