The chart is useful for tracking prices over time and aiding in trading decisions. Learn what is bar graph. A bar graph or a bar chart is used to represent data visually using bars of different heights or lengths. A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips. Some graphs may also have a legend that specifies what various colors represent, such as in a stacked bar graph. 2. The vertical axis of the bar graph is called the y-axis, while the bottom of a bar graph is called the x-axis. These bars are uniform in width but vary in height or length. In trading, bar graphs are often used to depict trading volume and will appear in a panel below a security's price chart. A bar graph shows comparisons among discrete categories. For example, if too large of a scale is chosen, then the data may appear insignificant—when in fact it could be very significant, but the scale doesn't allow for an appropriate comparison. Grouped bar graphs, also called clustered bar graphs, represent discrete values for more than one item that share the same category. The Certified Digital Marketer (CDM) Program shares in the Digital Marketing Analytics Specialist Track five basic data visualization tools to use when presenting data; time graph, bar chart, histogram, scatter plot and pie chart. For instance, a bar graph could display the number of males with a certain trait for specific ages. The dat… A bar graph is a mathematical representation of data. Bar graphs can be created to show data in multiple, highly visual ways. ‘The height of the columns varied, allowing the work to appear like a meandering bar graph.’ "What Is a Bar Graph?" Bar Graph A bar graph is a graph with rectangular bars with lengths and heightsproportional to the values that they represent. Stacked bar graphs or composite bar graphs divide an aggregate total into parts. Data is displayed either horizontally or vertically. For example, looking at only a few days worth of volume data in a stock doesn't provide much relevant information. The longest bar on the graph would represent the year from 1995 to 2010 in which the number of males in grades 4-6 reached its greatest value. However, unlike a bar graph, which represents the relationship between two different variables, a histogram represents only a single, continuous variable. In the single bar graph example above, only one item (the number of males in grades 4-6) is represented. As the information becomes more complex, so will the graph, which may even take the form of a grouped or clustered bar graph or a stacked bar graph. To switch the orientation, the x- and y-axis are switched. The y-axis, when the bins are evenly spaced, measures the frequency of the given values. more ... A graph drawn using rectangular bars to show how large each value is. They can be as simple, in some cases, as two bars, such as a graph representing the vote totals of two competing political candidates. In this lesson, you will learn the definition of a bar graph, including how to recognize the different types of bar graphs. Bar charts can be displayed with vertical columns, horizontal bars, comparative bars (multiple bars to show a comparison between values), or stacked bars (bars containing multiple types of information). What Is a Two-Way Table of Categorical Variables. Double Bar Graph - definition A double bar graph is a graphical display of data using two bars besides each other at various heights. A bar graph shows data in columns, while a bar chart is a technical analysis term describing the display of the open, high, low, close (sometimes the open is omitted) prices for a particular security during a specific time period using a vertical bar. A bar graph is a pictorial rendition of statistical data in which the independent variable can attain only certain discrete values. / ˈbɑːr ˌtʃɑːrt / (also bar graph) a mathematical picture in which different amounts are represented by thin vertical or horizontal rectangles that have the same width but different heights or lengths James Foulds/iStock / Getty Images Plus/GettyImages SMART Vocabulary: related words and phrases It is a graph whose bars are drawn horizontally. Bar graphs are used to display all kinds of data, from quarterly sales and job growth to seasonal rainfall and crop yields. Bar graphs are used to compare and contrast numbers, frequencies or other measures of distinct categories of data. Bar graphs have an x- and y-axis and can be used to showcase one, two, or many categories of data. The following daily chart of Apple Inc. shares shows three types of bar graphs. The title shows you what you are interpreting. A bar graph is a chart that plots data using rectangular bars or columns (called bins) that represent the total amount of observations in the data for that category. A bar graph is a chart that plots data using rectangular bars or columns (called bins) that represent the total amount of observations in the data for that category. The x-axis shows days, while a bar extending up from that day shows how much volume there was per the y-axis. Psychology Definition of BAR GRAPH: n. a method of displaying statistical data through rectangular bars which vary in length and height. The bars can be horizontal or vertical. The bars can be plotted vertically or horizontally. These parts are typically identified by utilizing different colors for each section. The shortest bar would represent the year in which the number of males in grades 4-6 reached its lowest value. The bars representing each gender by year would be grouped together and color-coded to make it clear which bars represent the male and female values. What does bar-graph mean? What is the definition of bar graph? Bar Graph : Bar graph is a pictorial representation of any statistics which is used to compare data.

Bar graphs take different forms depending on the type and complexity of the data they represent. Bar graphs are ideal for comparing two or more values, or values over time. bar graph synonyms, bar graph pronunciation, bar graph translation, English dictionary definition of bar graph. How do you use bar graph in a sentence? When interpreting a bar graph, the length of the bars/columns determines the value as described on the y-axis. Stacked: Some bar graphs have each bar divided into subparts that represent the discrete values for items that constitute a portion of the whole group. The vertical and horizontal lines are called axes. See: Histogram. Math Glossary: Mathematics Terms and Definitions. A stock volume chart is a commonly used type of vertical bar graph. A chart with rectangles (each representing a category) placed next to each other in which the length of each rectangle represents the amount of data in each category.YES 48% NO 43% DON'T KNOW 9% Note: Table made from bar graph.. Deb Russell is a school principal and teacher with over 25 years of experience teaching mathematics at all levels. 1. Bar Graph Definition A bar graph is a way to display data graphically by using rectangle bars. It is best to leave gaps between the bars of a Bar Graph, so it doesn't look like a Histogram. The aggregate number of instances could be combined into one bar. The x-axis could be any variable, such as time, or the category that is being measured, such as earnings per share (EPS), revenue, and/or cash flow. Histograms can be used to produce models of probability and to estimate the likelihood of certain outcomes. Single: Single bar graphs are used to convey the discrete value of the item for each category shown on the opposing axis. A bar graph or a bar chart is used to represent data visually using bars of different heights or lengths. Once you have completed the bar graph, you can make updates and adjustments by changing the values in the spreadsheet. Often the two sets of data have very different scales of measure, so a bar graph would not work. But one could very easily modify the graph by adding a second value that includes the number of females in grades 4-6.
