Final answer:
A histogram is a type of bar chart that displays the frequency distribution of a data set on a graph, with the measured variable on the X axis and frequency on the Y axis.
Step-by-step explanation:
A histogram is a type of bar chart, where the frequency for each score is plotted on the Y axis, and the measured variable is on the X axis. The histogram consists of contiguous rectangles that represent the frequency distribution of a data set. On the horizontal axis, which is akin to a number line, it displays quantitative data values divided into classes. The vertical axis, on the other hand, is labeled with frequencies or relative frequencies.
The heights of the bars in a histogram are proportional to the frequency values of the data. It is particularly useful for presenting and interpreting large data sets and can provide information about the shape, center, and spread of the data. This makes a histogram ideal for visualizing continuous variables, whereas a bar graph is better suited for categorical data.
Different types of charts like line graphs, pie charts, and scatter plots are used to represent data in various forms. In this context, a line graph would involve plotting frequency points on the Y axis and connecting them with line segments, but it is not the same as a histogram.
