you managed to explain in 6 minutes what takes most lecturers more than an hour, that is a remarkable talent

[@Quandale445]

FOR ANYBODY WONDERING HOW HE GOT SSG AS 16.33 and not -722: He accidentally wrote r=6 although it should be r=4. That is because r is the number of samples within a single group; in this case 4. So if you got -722, it's probably because you divided by 6 (the typo) and not 4 (the supposed value). Thank you.

How did you get the 16.33? Because what I got is a whole number in negative by doing the same computation. 🙁 Hope you can answer ASAP.

[@VectorsAcademy]

Divide it by '4' instead of '6'... there's a typing mistake.. sorry for trouble...

[@maxroar6450]

And the resuly is 17

[@maxroar6450]

And I wanna know, why 4? Why would I divide it by 4? Where am I going to get the 4 when there's a 6 groups?

[@maxroar6450]

Please, please, please 🙏 I hope you can answer me right awayy 🙏🙏

[@mikahamari5994]

@@maxroar6450 I believe that it is because of "degrees of freedom". There are 2 x 3 = 6 groups (for each gender three noise levels). For each gender there are 3-1=2 degrees of freedom in noise levels, so it makes 2+2=4. Maybe it is not exactly like this, but this is not arbitrary: the divider is always smaller than the amount of groups, because there is one degree of freedom (df) less. [Degrees of freedom: It comes from the concept that the last member in group is always known, so there is no freedom in making "choice". From numbers 1,2,3 you may choose 1,2 or 3. If you choose now 1, then you have one option less and may choose from 2 and 3. If you choose now 2, you have only number 3 left. So, in this group of three numbers you have two degrees of freedom (two choices).]
