英语词汇“statistic”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

A statistic is a numerical piece of information. If you are trying to prove a point, and you want your argument to have a sense of authority, you might want to use a statistic to back up your claim.

A statistic is a single piece of information represented by a number. “Water makes up 70% of the Earth’s surface,” for instance, is a statistic. A statistic is like a fact that is reached through a mathematical process. A population figure is the most common statistic you will encounter. When made plural, statistics means either a collection of statistics or the science of creating and interpreting statistics, as in “His favorite course in college was Statistics.”

n a datum that can be represented numerically

Hypo|Hyper

average, norm

a statistic describing the location of a distribution

demographic

a statistic characterizing human populations (or segments of human populations broken down by age or sex or income etc.)

deviation

the difference between an observed value and the expected value of a variable or function

moment

the n-th moment of a distribution is the expected value of the n-th power of the deviations from a fixed value

distribution free statistic, nonparametric statistic

a statistic computed without knowledge of the form or the parameters of the distribution from which observations are drawn

parametric statistic

any statistic computed by procedures that assume the data were drawn from a particular distribution

time series

a series of values of a variable at successive times

vital statistics

data relating to births and deaths and health and diseases and marriages

age norm

the average age at which particular performances are expected to appear

outlier

an extreme deviation from the mean

mean deviation, mean deviation from the mean

the arithmetic mean of the absolute values of deviations from the mean of a distribution

modal value, mode

the most frequent value of a random variable

median, median value

the value below which 50% of the cases fall

mean, mean value

an average of n numbers computed by adding some function of the numbers and dividing by some function of n

second moment

the expected value of the square of the deviations of a random variable from the point of origin

variance

the second moment around the mean; the expected value of the square of the deviations of a random variable from its mean value

regression coefficient

when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line

coefficient of correlation, correlation, correlation coefficient

a statistic representing how closely two variables co-vary; it can vary from -1 (perfect negative correlation) through 0 (no correlation) to +1 (perfect positive correlation)

rank-difference correlation, rank-difference correlation coefficient, rank-order correlation, rank-order correlation coefficient

the most commonly used method of computing a correlation coefficient between the ranks of scores on two variables

Kendall test

any of several nonparametric measures of correlation (used when the assumptions of standard correlational analysis are not met)

fourfold point correlation, phi coefficient, phi correlation

an index of the relation between any two sets of scores that can both be represented on ordered binary dimensions (e.g., male-female)

data point, datum

an item of factual information derived from measurement or research
