The particular descriptive statistics used depend on the scale that has been used to assign numbers to represent the characteristics of entities being studied. When the distribution of continuous data is bell shaped, we have convenient properties that make description easier. Chapter 2 looks at ...
Graphs can visually show the data distribution.Examples of graphs include:Histograms Pie charts Bar graphs Box plotsSome graphs have a close connection to numerical summary statistics. Calculating those gives us the basis of these graphs.For example, a box plot visually shows the quartiles of a ...

Another Family of Distributions for Describing and Analyzing Precipitation Data. A positively skewed two-parameterer family of distributions is introduced as an alternative description of precipitation amounts. Each distribution of this family is associated with a simple two-sample non-parametric test ...

Data mining methods can be applied to human resources datasets to discover insights into how employees manage their careers. We examine two elements of career trajectories in federal government HR data. First, we apply association rule mining and sequential pattern mining to understand the prevalence ...

Probability distribution function:a graph depicting the probabilities of occurrence of different possible outcomes for a data set or experiment. Standard error of the mean:indicates how accurate the sample estimates the mean of the population, and as the number increases, the estimate accuracy decreases...
