Discrete data refers to specific and distinct values, while continuous data are values within a bounded or boundless interval. Discrete data and continuous data are the two types of numerical data used in the field of statistics.
Continue ReadingData is generally classified into two categories: descriptive and numerical. Descriptive data, also called qualitative or categorical data, are represented by words that characterize a set of values while numerical data, known as quantitative data, are denoted by numbers. In discrete data, the number of possible values is countable, while continuous data is measurable and can take on infinite values. Some examples of discrete data include shoe size, set of natural numbers and number of siblings. Distance, set of real numbers and mass are some common examples of continuous data.

Full Answer >The box-and-whisker plot is a technique in statistics that graphically shows the distribution of a set of data involving the minimum and maximum values, as well as the first, second and third quartiles. The plot is typically drawn using a number line.
Full Answer >The midrange is the average of the maximum and minimum values of a set of data. This measure of center is not as common as the mode, mean or median.
Full Answer >The mean of a set of data can be easily approximated by taking an average of the values in that data. In order for the mean to be representative, the group of numbers must be comparable values in the same category.
