Can you rename the function to "clearTestView" or something like this to make the purpose clearer? Are the global vars necessary? If not, please avoid them.

OK. Please add a TODO-comment about this issue so we can check it later again.

> yes it should be gsl_cdf_gaussian_P. Actually, I have left ztest backend for now, I am not able to find online calculator and neither ztest is included in JASP. So for time being, I am not concentrating on it.

Please add a TODO-comment in the code that the value is not tested.

> Is this not correct or less efficient?

It's surely less efficient since you call currentText() three times and compare each time to a string. Also the comparison will fail when the text is translated.

If it would be more complex, leave it like it is. I just wanted to point out other popular solutions.
