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.
Frequency Distributions. â¢ After collecting data, the first task for a researcher is to. organize and summarize the data to get a general overview of. the results. â Remember, this is the goal of descriptive statistical techniques. â¢ One method for simplifying and organizing data is to construct. a frequency distribution. â Frequency â describes the number of times or how often a category, score, or range of scores occurs. â Frequency distribution â a summary display for a distribution of data. 01:830:200:01-05 Fall 2013.
