Q 4.3. - The Practice of Statistics for AP

Question

Is this a bar graph or a histogram? 

Step-by-Step Solution

Answer

The given graph is a bar graph.  

Step 1: Given information

The graph above depicts the proportion of first-year students who intend to major in one of the various fields. 

Step 2: Concept

Quantitative variables can have a wide range of values. When adjacent values are grouped together, a graph of the distribution becomes clearer. A histogram is the most frequent graph for displaying the distribution of a single quantitative variable.

Step 3: Explanation

The graph above shows data on the percentage of first-year students who plan to major in certain disciplines. To compare the sizes of distinct groups, both bar charts and histograms can be utilized. A bar chart is a graph with bars that are plotted on it. The heights of the bars representing observed frequencies are represented by the histogram in general, and there is no space between adjacent bars of the histograms in general. A histogram is a graphical representation of data in which the data is represented by bars of varied heights. A bar graph, on the other hand, is formed up of bars that are drawn on the graph. The group size is determined by the column height, which is determined by the categories. As a result, the supplied graph is a bar graph.
