BHS220-Mod3 Discussion: Descriptive Statistics
BHS 220-Discussion-Module 3 What's in a data set? As we continue on with descriptive statistics, Identify three uses for a frequency distribution. Please provide realistic health related examples. Briefly identify the differences between a normal, positive and negative skew. How does this skew or distribution curve relate to standard error? What does the standard error mean for the results? Feel free to use and example to explain your answer. In preparing your response, ensure that you properly in-text cite all sources used in the support of your stated positions and the example or examples you chose to utilize. The response needs to be a minimum of 250 words. Also, you will need to include the references at the end of your posting. References Salkind, N. J. (2012). Exploring research. (8th ed.).

Descriptive Statistics
A data set contains values obtained from a database or a study, where each column or row bears a representation of a particular variable. The set has values that are set for each of the figures collected in the said statistic called a datum (Munro, 2005). The data sets to be analyzed include the statistical figures obtained from the sampling of a population and their characteristic of interest, such as the prevalence of the disease.
The uses of a frequency distribution range from; analysis, classification and manipulation of qualitative and quantitative data, for the creation of graphical representation of the data in question (Salkind, 2012). The tabulated data makes it simple and easy to compute the median, mean and the standard deviation. In the case that statistics on health are given, it is necessary to organize the numbers in terms of distribution and the classification- such as that of persons at risk of infection, away from persons already infected. The frequency distribution is also usable ...
