Answer to Problem 1CFU

The comparison and the contrast for the line plot, bar graph, histogram, and frequency polygon is described.

Explanation of Solution

Consider that the line plot uses symbols to shows the frequency, bar frequency shows that the information by the use of the bars to indicate the frequency.

The back to back graph is the special bar graph that shows the comparison of the two set of the related data and back to back graph that is to be potted on the coordinate system with the horizontal scale that is repeated in each of the direction from the central axis. It is sometime desirable to show the three aspects of the data set of the data and the same time. This is used to represent the data the data in the similar way, thus data dimensional graph is used.

Consider the histogram is the type of graph in such way that the width of the bar represents the class interval and the height of the bar that represents the frequency in the given interval.

Consider the frequency polygon is drawn by the connection of the class marks, thus the glass marks is graphed as the midpoints of the top edge of the each bar.
