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 Distribution. Frequency distribution is a simple (basic, not necessarily easy) type of statistic that people often make into a much bigger deal than it really is. Let's say you are in a class with 100 people, and you have just taken a test. The teacher then tells you that on the test, there were 20 As, 25 Bs, 35 Cs, 15 Ds, and 5 Fs. What the teacher has just given you is a frequency distribution; a breakdown of how all the scores fell into the different categories or ranges that the overall score was broken into.
