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.
