Magazine Chapter 1: Q. 4.3 (page 41)
About 1.6 million first-year students enroll in colleges and universities each year. What do they plan to study? The graph displays data on the per cent of first-year students who plan to major in several discipline areas.
Is this a bar graph or a histogram? Explain.
Short Answer
The provided graph is a bar graph.
Step by step solution
Definition of Bar-diagram and Histogram and given informations
The bar diagram is a graphical presentation of categorical data using rectangular bars. Each bar represents a factor and the length of each bar represent the factor's value. The histogram is a graphical representation of some data. The groups of data are grouped into number ranges and the ranges are corresponding to a vertical bar.
Given information:
Findings if the given graph is a Bar-graph or Histogram
The graph represents data on per cent achieved by the students in the year. The students plan to major in some discipline areas.
A histogram and Bar-diagram both can compare the sizes of different groups but a bar chart is composed of bars that are shown in the graph. The histogram generally represents some consequent distribution of data and the height distribution of the bar represents the observed frequencies. The adjacent bars have no space between them in a histogram. A graphical representation of data using bars of various heights is a Histogram. Whereas a bar-graphs are made of many bars which are plotted on the graph and the column height represents the group size which is defined by categories.
Thus, the given graph is a bar graph.
