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. This is an example of a univariate (=single variable) frequency table. The frequency of each response to a survey question is depicted.
In statistics, count data is a statistical data type describing countable quantities, data which can take only the counting numbers, non-negative integer values ...
The count rates of cps and cpm are generally accepted and convenient practical rate measurements. They are not SI units , but are de facto radiological units of measure in widespread use. Counts per minute (abbreviated to cpm) is a measure of the detection rate of ionization events per minute.
In epidemiology, a rate ratio, sometimes called an incidence density ratio or incidence rate ratio, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time.
In statistics, data can have any of various types.Statistical data types include categorical (e.g. country), directional (angles or directions, e.g. wind measurements), count (a whole number of events), or real intervals (e.g. measures of temperature).
The list of countries by homicide rate is derived from United Nations Office on Drugs and Crime (UNODC) data, and is expressed in number of deaths per 100,000 population per year. For example, a homicide rate of 30 out of 100,000 is presented in the table as "30", and corresponds to 0.03% of the population dying by homicide.
In mathematics, a rate is the quotient of two quantities, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the corresponding rate of change ...
A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features from a collection of information, [1] while descriptive statistics (in the mass noun sense) is the process of using and analysing those statistics.
