The bars can be plotted vertically or horizontally. a bar graph in the form of a circle cut into wedges,also called a pie chart. Each bar represents a value. The first step, in the construction of histogram, is to take the observations and split them into logical series of intervals … Bar graphs use rectangular blocks to represent many different types of data, whereas line graphs use lines and represent trends over time particularly well. Stacked bar chart. Grouped bar graph is also called the clustered bar graph, which is used to represent the discrete value for more than one object that shares the same category. Change the scale of the vertical axis so that it does not start at 0. In other words, it hides the quantity and represents the relative difference between quantities in each group. (iii) What is the difference between the maximum and minimum production of rice in the time span of 1978-1983. In other words, a grouped bar graph is a type of bar graph in which different sets of data items are compared. A bar graph is a visual way of displaying what the data looks like after it's been sorted. Each subgroup represents a "snapshot" of the process at a given point in time. The bars represent frequencies of distinctive values of a variable or commonly the distinct values themselves. A time-series graph displays data at different points in time, so it is another kind of graph to be used for certain kinds of paired data.

Line graphs show trends over time. They can be used to track changes over time for one or more groups. The data are discrete. They are as follows. Represent it using bar charts. They consist of an axis and a series of labeled horizontal or vertical bars. One axis will generally have numerical values, and the other will describe the types of categories being compared. From this data we can now construct an appropriate graphical representation which, in this case will be a Bar Chart. Meanwhile, a bar chart can be used for a broader range of data types, not just for breaking down a whole into components. The data are on a nominal scale. Graph is not labeled properly.

The number of values on the x-axis of a bar graph or the y-axis of a column graph is called the scale. Bar Graphs. Uses of Bar Graphs. Here we will take a look at the most popularly used: pie charts, bar graphs, statistical maps, histograms, and frequency polygons. The bars’ heights are scaled according to their values and the bars can be compared to each other. Space between two consecutive bars is same throughout. … This is because a histogram represents a continuous data set, and as such, there are no gaps in the data (although you will have to decide whether you round up or round down scores on the boundaries of bins). The orientation of the x-axis and y-axis are changed depending on the type of vertical and horizontal bar chart. What is the most common trick to mislead readers of bar graphs? The pictorial representation of a grouped data, in the form of vertical or horizontal rectangular bars, where the lengths of the bars are equivalent to the measure of data, are known as bar graphs or bar charts. In the year 1979-80, the production of rice is minimum and is equal to 25 lakh tons. We use bar graphs for displaying discrete data, and histograms for displaying continuous data. Under what circumstances would a bar graph rather than a histogram be used? 12) Are their circumstances when a pie chart cannot be drawn, but a bar graph could be drawn?
