@@joshemmanis this just for hypothesis tests using the Z score? For example, for a 95% confidence the t-value will be 0.05 for both one tail and two tail but this isnt the same case for z value?
@@nadofm Z and t work the same way. 95% confidence (two-tails) will have 0.025 in each tail. Whereas, for a one-tailed test, there is 0.05 in one tail.

Is it one tailed or two tailed if trying to see something is more effective than the previous study?
"more effective" will be one tailed.
is the formula / critical score the same? so the only thing we are changing is the hypothesis?
The formula (test statistic) will not chnage. The critical value will change based on the tail(s) of the test.
