COM.MICROSOFT.CHISQ.DIST

CHISQDIST

Returns the probability value from the indicated Chi square that a hypothesis is confirmed. CHISQ.DIST.RT compares the Chi square value to be given for a random sample that is calculated from the sum of (observed value-expected value)^2/expected value for all values with the theoretical Chi square distribution and determines from this the probability of error for the hypothesis to be tested.

CHISQINV

Returns the inverse of the one-tailed probability of the chi-squared distribution.

Sintaxe

CHISQ.INV.RT(Number; DegreesFreedom)

N煤meroX 茅 o valor da coordenada x.

DegreesFreedom is the degrees of freedom of the experiment.

Exemplo

A die is thrown 1020 times. The numbers on the die 1 through 6 come up 195, 151, 148, 189, 183 and 154 times (observation values). The hypothesis that the die is not fixed is to be tested.

The Chi square distribution of the random sample is determined by the formula given above. Since the expected value for a given number on the die for n throws is n times 1/6, thus 1020/6 = 170, the formula returns a Chi square value of 13.27.

If the (observed) Chi square is greater than or equal to the (theoretical) Chi square CHIINV, the hypothesis will be discarded, since the deviation between theory and experiment is too great. If the observed Chi square is less that CHIINV, the hypothesis is confirmed with the indicated probability of error.

=CHISQ.INV.RT(0.05;5) returns 11.0704976935.

=NORMSINV(0.908789) devolve 1,3333.

If the probability of error is 5%, the die is not true. If the probability of error is 2%, there is no reason to believe it is fixed.

note

This function ignores any text or empty cell within a data range. If you suspect wrong results from this function, look for text in the data ranges. To highlight text contents in a data range, use the value highlighting feature.


Exemplo

The entries 2, 4, 6 and eight in the Value 1-4 fields are to be counted.

=COUNT(2;4;6;"eight") = 3. The count of numbers is therefore 3.

Sintaxe

COUNTA(Number 1 [; Number 2 [; 鈥 [; Number 255]]])

Number 1, Number 2, 鈥 , Number 255 are numbers, references to cells or to cell ranges of numbers.

Exemplo

The entries 2, 4, 6 and eight in the Value 1-4 fields are to be counted.

=COUNTA(2;4;6;"eight") = 4. The count of values is therefore 4.

A reference to an empty cell is interpreted as the numeric value 0.

A matching expression can be:

The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every regular expression metacharacter or operator with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in - LibreOffice Calc - Calculate.

warning

Ao empregar funci贸ns nas que un ou m谩is argumentos sexan criterios de busca que representen unha expresi贸n regular, t茅ntase primeiro converter os criterios da cadea en n煤meros. Por exemplo, 芦.0禄 conv茅rtese en 0.0, etc. Se resulta ben, a busca non ser谩 unha coincidencia de expresi贸n regular sen贸n unha coincidencia num茅rica. Por茅n, ao traballar cunha configuraci贸n rexional na que o separador decimal non sexa o punto, como en galego, o punto fai que funcione a conversi贸n a expresi贸n regular. Para obrigar a que a avaliaci贸n sexa dunha expresi贸n regular no canto dunha expresi贸n num茅rica hai que empregar algunha expresi贸n que non se poda confundir cunha num茅rica, como 芦.[0]禄, 芦.\0禄 ou 芦(?i).0禄.


Exemplo

A1:A10 is a cell range containing the numbers 2000 to 2009. Cell B1 contains the number 2006. In cell B2, you enter a formula:

=COUNTIF(A1:A10;2006) - this returns 1.

=COUNTIF(A1:A10;B1) - this returns 1.

=COUNTIF(A1:A10;">=2006") - this returns 4.

=COUNTIF(A1:A10;"<"&B1) - when B1 contains 2006, this returns 6.

=COUNTIF(A1:A10;C2) where cell C2 contains the text >2006 counts the number of cells in the range A1:A10 which are >2006.

Para resumir s贸 n煤meros negativos: = SUMIF (A1: A10;"<0")
