Hello everybody,
Currently we have been trying to execute the z_test(data, value, stdev) function based on a bunch of data between test/control groups.
What the documentation is lacking is a bit of description on how does each of this input need to be given:
- data - what data does it refer to?
- value - the hypothesized mean
- stdev - the standart deviation
For the last 2 inputs, I already have data. But which input should I give on data?
