Description of Returned Value

AveDev

Returns the average of the absolute mean deviations of data points. AveDev is a measure of the variability in a data set.

Format: AveDev(number1, number2, ...)

Average

Returns the average (arithmetic mean) of the arguments.

Format: Average(number1, number2, ...)

AverageA

Returns the average (arithmetic mean) of the arguments. In addition to numbers and text, logical values such as True and False can also be included.

Format: AverageA(value1, value2, ...)

Avg

Returns the average (arithmetic mean) of the arguments.

Format: Avg(number1, number2, ...)

BinomDist

Returns the individual term binomial distribution probability.

Format: BinomDist(number, trials, probability, cumulative)

ChiDist

Returns the one-tailed probability of the chi-squared distribution. The chi distribution is associated with a chi test.

Format: ChiDist(x, degrees_freedom)

ChiInv

Returns the inverse of the one-tailed probability of the chi-squared distribution. If probability = CHIDIST(x,...), then CHIINV(probability,...) = x. Use this function to compare observed results with expected ones to decide whether your original hypothesis is valid.

Format: ChiInv(probability, degrees_freedom)

Confidence

Returns a value to construct a confidence interval about a population mean. The confidence interval is a range of values. In a sample, mean x is at the centre of this range and the range is x » Confidence. For example, if x is the sample mean of delivery times for products ordered through the mail, x » Confidence is a range of population means.

Format: Confidence(alpha, standard_dev, size)

Count

Counts the number of items in a list that contains numbers.

Format: Count(value1, value2,...)

CountA

Counts the number of cells that are not empty.

Format: CountA(value1, value2,...)

CritBinom

Returns the smallest value for which, the cumulative binomial distribution is greater than or equal to a criterion value.

Format: CritBinom(trials, probability_s, alpha)

DevSq

Returns the sum of squares of deviations of data points from their sample mean.

Format: DevSq(number1, number2, ...)

ExponDist

Returns the exponential distribution.

Format: ExponDist(x, lambda, cumulative)

Fisher

Returns the Fisher transformation.

Format: Fisher(x)

FisherInv

Returns the inverse of the Fisher transformation.

Format: FisherInv(y)

GammaDist

Returns the gamma distribution.

GammaInv

Returns the inverse of the gamma distribution.

Format: HarMean(number1, number2, ...)

HypGeomDist

Returns the hypergeometric distribution.

Format: HypGeomDist(sample, n_sample, population, n_population)

Returns the kurtosis of a data set. Kurtosis characterises the relative peakedness or flatness of a distribution compared with the normal distribution. Positive kurtosis indicates a relatively peaked distribution. Negative kurtosis indicates a relatively flat distribution.

Format: KURT(number1, number2, ...)

LogInv

Returns the inverse of the lognormal cumulative distribution function of x, where ln(x) is normally distributed with parameters mean and standard_dev. If p = LogNormDist(x,...), then LogInv(p,...) = x.

Format: LogInv(probability, mean, standard_dev)

LogNormDist

Returns the cumulative lognormal distribution of x.

Format: LogNormDist(x, mean, standard_dev)
