ZTEST
Definition
Returns the two-tailed P-value of a Z-test with standard distribution.
Sample Usage
ZTEST(A2:A100,B2)
ZTEST({1,2,3,4,5,6},5.5,1.2)
Syntax
ZTEST(data, value, [standard_deviation])
data- The array or range containing the dataset 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
ZTESTis the probability that a value chosen at random fromdatais at least as extreme (that is, as far from the mean) asvalue.
