# Types of Statistics

Char - a Single Character To declare a char value in C# we just surround the character with single quotes: 'x'. But what is the "clearest" way to declare a char value that is a single quote/apostrophe?

Double - a Double-Precision Floating Point Value The standard floating-point variable in C++ is its larger sibling, the double-precision floating point or simply double. You declare a double-precision floating point as follows: double dValue1; double dValue2 = 1.5; The limitations of the int variable in C++ are unacceptable in some applications.

Measures of Central Tendency Measures of Central Tendency Introduction. A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. As such, measures of central tendency are sometimes called measures of central location. They are also classed as summary statistics.

Measures of Dispersion or Variation In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.

Measures of Frequency: * Count, Percent, Frequency The relative frequency (or empirical probability) of an event is the absolute frequency normalized by the total number of events: = = ∑. The values of for all events can be plotted to produce a frequency distribution.

Measures of Position Measures of Position Statisticians often talk about the position of a value, relative to other values in a set of data. The most common measures of position are percentiles, quartiles, and standard scores (aka, z-scores).

Measures of Position * Percentile Ranks, Quartile Ranks Both percentiles and quartiles are statistical measures of position; that is, they do not measure a central tendency or a spread (dispersion), but instead measure location in a data set. (The exact definition of a percentile and quartile differs; these differences, however, tend to be minor and are focused on certain fine points.

Void The Void is the philosophical concept of nothingness manifested. The notion of the Void is relevant to several realms of metaphysics. The Void is also prevalent in numerous facets of psychology, notably logotherapy.
