A bibliography is a list of works (books, articles, films, etc.) on a particular topic. Annotated bibliographies tell more about the work you are citing. An annotation can both describe and evaluate a source.An annotated bibliography includes a paragraph following each citation that summarizes the work.
A frequency polygon is a graphical display of a frequency table. The intervals are shown on the X-axis and the number of scores in each interval is represented by the height of a point located above the middle of the interval.The points are connected so that together with the X-axis they form a polygon.A frequency table and a relative frequency polygon for response times in a study on weapons and aggression are shown below. The times are in hundredths of a second.Frequency polygons are useful for comparing distributions.he intervals are shown on the X-axis and the number of scores in each interval is represented by the height of a point located above the middle of the interval. The points are connected so that together with the X-axis they form a polygon.
Count the tallies for the frequency in each class. The following are techniques for representing quantitative data 1  : A frequency histogram is a bar graph that represents the frequency distribution of the data set. 2  A frequency polygon is a line graph that represents the frequency distribution of the data set.he following is the frequency histogram plotted by Minitab for the Internet Usage data on p 33. Note that Minitab uses the exact value of 81/7 to find the class boundaries. Construction a Frequency Polygon in Minitab (Manual p 51). The polygon should be modified to include our breakpoints and bins.
