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.
To create a frequency distribution using FREQUENCY: 1  Enter numbers that represent the bins you want to group values into. 2  Make a selection the same size as the range that contains bins, or one greater if want to include the extra item. 3  Enter the FREQUENCY function as an array formula using Control+Shift+Enter.
