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.
A frequency distribution table is one way to organize data so that it makes more sense. The data so distributed is called frequency distribution and the tabular form is called frequency distribution table. Let us see with the help of example how to construct distribution table.he cumulative frequency for each class interval is the frequency for that class interval added to the preceding cumulative total. Cumulative frequency can also defined as the sum of all previous frequencies up to the current point. Cumulative relative frequency distribution is one type of frequency distribution.
