Graphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. The x-axis may contain categories or numbers. You read it from the bottom left of the graph.
In analytic geometry, graphs are used to map out functions of two variables on a Cartesian coordinate system, which is composed of a horizontal x-axis, or abscissa, and a vertical y-axis, or ordinate. Each axis is a real number line, and their intersection at the zero point of each is called the origin.
To interpret a graph or chart, read the title, look at the key, read the labels. Then study the graph to understand what it shows. Read the title of the graph or chart. The title tells what information is being displayed.
Displaying data from an experiment with a graph makes it easier to see trends and patterns in the data. The graph presents the data in a visual format that often brings out the significance of the data much more clearly than a data table.
Graphs condense detailed numerical information to make it easier to see patterns (such as “trends”) among data. … Economists use graphs not only as a compact and readable presentation of data, but also for visually representing relationships and connections—in other words, they function as models.
Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. … If the data shows pronounced trends or reveals relations between variables, a graph should be used.
The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.
Use precise vocabulary like steadily declined and a sharp increase to describe trends. Use linking expressions like while and in contrast to make comparisons. The question asks you only to ‘Summarise the information’. Don’t give reasons why these trends might have occurred, or your personal preferences on the topic.
a diagram that shows a relationship between two or more changing things by lines, bars, dots, or portions of a circle.
Bring your data to life with engaging charts and graphs. Visual representations help us to understand data quickly. When you show an effective graph or chart, your report or presentation gains clarity and authority, whether you’re comparing sales figures or highlighting a trend.
A graph is a common data structure that consists of a finite set of nodes (or vertices) and a set of edges connecting them. … For example, a single user in Facebook can be represented as a node (vertex) while their connection with others can be represented as an edge between nodes.
A graph processing framework (GPF) is a set of tools oriented to process graphs. Graph vertices are used to model data and edges model relationships between vertices. … Since real graphs can be large, complex, and dynamic, GPFs have to deal with the three challenges of data growth: volume, velocity, and variety.
Interpreting graphs involves understanding what the shape of a curve represents in real life situations. We should also understand what slope means and how to interpret what a high or low slope value represents. An understanding of plotting points is also important.
Graphs are used in everyday life, from the local newspaper to the magazine stand. It is one of those skills that you simply cannot do without. Whatever your need or calculation, if used correctly, a graph can help you and make your life simpler. A graph can help you keep track of things and to be on top of your game.
Why are graphs useful when interpreting data? They make trends in the data easier to see. They are easier to create than data tables. … They can be used to show additional data.
Overview: Two graphs that can be used to summarize the distribution for a single quantitative variable or response are a histogram and a boxplot. Each graph provides different information about the distribution. When used properly, graphs can be a very effective way to summarize data.
Graphs and charts communicate information visually. They can show patterns, help scientists identify correlations, and get the point of the experiment across quickly. The dependent variable is plotted on the y-axis.
