Arithmetic mean
In mathematics and statistics, the arithmetic mean (stress on third syllable of "arithmetic"), or simply the mean or average when the context is clear, is the sum of a collection of numbers divided by the number of numbers in the collection.

Box plot
In descriptive statistics, a box plot or boxplot is a method for graphically depicting groups of numerical data through their quartiles.

Descriptive statistics
A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features of a collection of information, while descriptive statistics in the mass noun sense is the process of using and analyzing those statistics.

Epidemiology
Epidemiology is the study and analysis of the distribution (who, when, and where) and determinants of health and disease conditions in defined populations.

Finance
Finance is a field that is concerned with the allocation (investment) of assets and liabilities (known as elements of the balance statement) over space and time, often under conditions of risk or uncertainty.

Five-number summary
The five-number summary is a set of descriptive statistics that provide information about a dataset.

Interquartile range
In descriptive statistics, the interquartile range (IQR), also called the midspread or middle 50%, or technically H-spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR.

John Tukey
John Wilder Tukey (June 16, 1915 – July 26, 2000) was an American mathematician best known for development of the FFT algorithm and box plot.

Median
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half.

Midhinge
In statistics, the midhinge is the average of the first and third quartiles and is thus a measure of location.
New!!: Quartile and Midhinge · See more »
Outlier
In statistics, an outlier is an observation point that is distant from other observations.
New!!: Quartile and Outlier · See more »
Percentile
A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall.

Probability density function
In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function, whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample.

Quantile
In statistics and probability quantiles are cut points dividing the range of a probability distribution into contiguous intervals with equal probabilities, or dividing the observations in a sample in the same way.
New!!: Quartile and Quantile · See more »
Range (statistics)
In statistics, the range of a set of data is the difference between the largest and smallest values.
New!!: Quartile and Range (statistics) · See more »
Robust statistics
Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal.
New!!: Quartile and Robust statistics · See more »
Sociology
Sociology is the scientific study of society, patterns of social relationships, social interaction, and culture.
New!!: Quartile and Sociology · See more »
Standard deviation
In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
New!!: Quartile and Standard deviation · See more »
Statistics
Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.

Summary statistics
In descriptive statistics, summary statistics are used to summarize a set of observations, in order to communicate the largest amount of information as simply as possible.

TI-83 series
