Purpose. An annotated bibliography describes the field of research on a topic and should include sources that reflect the range of approaches to the subject. The annotations tend to do one or both of two things: Description: a descriptive annotation provides a brief overview of the text.
In statistics, a frequency distribution is a table that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.he kurtosis of a frequency distribution is the concentration of scores at the mean, or how peaked the distribution appears if depicted graphicallyâfor example, in a histogram. If the distribution is more peaked than the normal distribution it is said to be leptokurtic; if less peaked it is said to be platykurtic.
Raw Data. Data collected in original form. Frequency. The number of times a certain value or class of values occurs. Frequency Distribution. The organization of raw data in table form with classes and frequencies. frequency distribution where several numbers are grouped into one class. Class Limits. Separate one class in a grouped frequency distribution from another. The limits could actually appear in the data and have gaps between the upper limit of one class and the lower limit of the next.
