Describe a frequency distribution, what it is used for, how it is constructed, and two ways that it can be shown graphically
What will be an ideal response?
Answer will include that a frequency distribution is a table that divides an entire range of scores into a series of classes and then records the number of scores that fall into each class. By using a frequency distribution, large amounts of information can be neatly organized and summarized. A frequency distribution is made by breaking down the entire range of possible scores into classes of equal size. Next, one sorts the scores and records the number of scores falling into each class. Frequency distributions are often shown graphically to make them more "visual.". A histogram or a frequency polygon can be used to display the scores. A histogram is a graph of a frequency distribution in which the number of scores falling in each class is represented by vertical bars. A frequency polygon is a graph of a frequency distribution in which the number of scores falling in each class is represented by points on a line.
