Returns the one-tailed p-value of a z-test with standard distribution.
Sample usage
Z.TEST(A2:A100,B2)
Z.TEST({1,2,3,4,5,6},5.5,1.2)
Syntax
Z.TEST(data, value, [standard_deviation])
-
data
– The array or range containing the data set to consider. -
value
- The test statistic to use in the z-test. -
standard_deviation
– [ OPTIONAL ] - The standard deviation to assume for the z-test. If this is not provided,STDEV(data)
will be calculated.
Notes
- The p-value returned by
Z.TEST
is the probability that a randomly generated sample (of the same size as the data) has a mean value greater than that of the original data set. - You can use
ZTEST
or Z.TEST to perform this function.
