Statistical Functions

AVEDEV

Article Returns the average of the absolute deviations of data points from their mean. AVEDEV is a measure of the variability in a data set. Syntax AVEDEV ( number1...

AVERAGE

Article Show All Hide All Returns the average (arithmetic mean) of the arguments. Syntax AVERAGE ( number1 ,number2,...) Number1, number2, ...      are 1 to 30...

AVERAGEA

Article Calculates the average (arithmetic mean) of the values in the list of arguments. Syntax AVERAGEA ( value1 ,value2,...) Value1, value2, ...   are 1 to 30...

BETADIST

Article Returns the cumulative beta probability density function. The beta distribution is commonly used to study variation in the percentage of something across...

BETAINV

Article Returns the inverse of the cumulative beta probability density function for a specified beta distribution. That is, if probability = BETADIST(x,...), then...

BINOMDIST

Article Returns the individual term binomial distribution probability. Use BINOMDIST in problems with a fixed number of tests or trials, when the outcomes of any...

CHIDIST

Article Returns the one-tailed probability of the chi-squared distribution. The χ 2 distribution is associated with a χ 2 test. Use the χ 2 test to compare...

CHIINV

Article Returns the inverse of the one-tailed probability of the chi-squared distribution. If probability = CHIDIST(x,...), then CHIINV(probability,...) = x. Use...

CHITEST

Article Returns the test for independence. CHITEST returns the value from the chi-squared (χ 2 ) distribution for the statistic and the appropriate degrees of freedom...

CONFIDENCE

Article Returns a value that you can use to construct a confidence interval for a population mean. The confidence interval is a range of values. Your sample mean...

CORREL

Article Returns the correlation coefficient of the array1 and array2 cell ranges. Use the correlation coefficient to determine the relationship between two properties...

COUNT

Article Syntax: COUNT(value1,value2,...)

COUNTA

Article Show All Hide All Counts the number of cells that are not empty and the values within the list of arguments. Use COUNTA to count the number of cells that...

COUNTBLANK

Article Show All Hide All Counts empty cells in a specified range of cells. Syntax COUNTBLANK ( range ) Range      is the range from which you want to count the...

COUNTIF

Article Syntax: COUNTIF(range,criteria)

COVAR

Article Show All Hide All Returns covariance, the average of the products of deviations for each data point pair. Use covariance to determine the relationship between...

CRITBINOM

Article Returns the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value. Use this function for quality assurance...

DEVSQ

Article Show All Hide All Returns the sum of squares of deviations of data points from their sample mean. Syntax DEVSQ ( number1 ,number2,...) Number1, number2...

EXPONDIST

Article Show All Hide All Returns the exponential distribution. Use EXPONDIST to model the time between events, such as how long an automated bank teller takes...

FDIST

Article Returns the F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you...

FINV

Article Returns the inverse of the F probability distribution. If p = FDIST(x,...), then FINV(p,...) = x. The F distribution can be used in an F-test that compares...

FISHER

Article Returns the Fisher transformation at x. This transformation produces a function that is normally distributed rather than skewed. Use this function to perform...

FISHERINV

Article Returns the inverse of the Fisher transformation. Use this transformation when analyzing correlations between ranges or arrays of data. If y = FISHER(x...

FORECAST

Article Calculates, or predicts, a future value by using existing values. The predicted value is a y-value for a given x-value. The known values are existing x...

FREQUENCY

Article Calculates how often values occur within a range of values, and then returns a vertical array of numbers. For example, use FREQUENCY to count the number...
