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. A frequency distribution shows the number of individuals located in each category of a categorical variable. For continuous variables, frequencies are displayed for values that appear at least one time in the dataset. frequency distribution not only presents an organized picture of how individual scores are distributed on a measurement scale, but also reveals extreme values and outliers. Researchers can make decisions on whether and how to recode or perform data transformation based on the distribution statistics.
