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.
@@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).]
It is really amazing, I want to understand how to deal with this and further study between genders and noise keeping other constant. I am interested in Categorical Analysis of Variance (CATNOVA)
Thanks for Good explanations in few minutes, just small corrections and confirmations: My SSg=-722 Total is 273.33 and not 59.22 in the table you gave. Lastly based on your table, F ratio value of gender should be 9.708 and not 9.81. I stand to be corrected.
I've x= 14 and x²= 42 in my book and not this but all x² writter then are not matching with x² of the x. Do you've a mail so i can share. Tried everything but don't know how this x² is coming and it can't be printing error in all answers
very useful and simple steps to understand sir. but one correction is needed- IN SSG calculation, you have to divide by 4-not with 6 sir. can you correct it !
While computing the sum of squares within groups, do you divide by the number of groups (=6) or by the number of individual group observations (=4), which is the same for all 6 groups!?
Should divide it by 4 instead of 6.. There's a typing error... Also in the table SST is wrongly typed... (That doesn't interfere with the answer though)
I do not know if you were able to get the answer as at the moment I am writing this comment, a significant amount of time has passed. Still if you calculate the column total i. e. 90+88+40 and take out the square of the value, divide it by 24 or N, you'll get 1980.
Thanks a lot sir... You explained it wery well. But what about its LSD ? Because when the Fratio is greater than Ftab value then we have to calculate its LSD . Kindly solved out my confusion
A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. So the answers is YES. Without it we won't be able to make out whether our expt is working or not.
Thank you so much for the quick response! I am planning to compare the effect of two independent variables (type of sweetener and daily intake frequency) on one dependent variable (antioxidant capacity). For each type of sweetener, 7 mice will take it once a day, another 7 twice a day, and another 7 thrice a day. Is it right if my negative control also contains 7 mice? Thank you so much!

How did you get the value of 16.33 in “Sum of Squares within groups(SSG)?” because when I calculated it the answer is -722. Just asking.
(2)
i scrolled thru comments and he said it should be divided by 4 instead of 6. so the answer shall be 17
I'm also stuck here does anyone know
please why are we dividing by 4
Sum of square within the group => r=3(no. Of elements in a group i.e. 3)
It should be 4... Instead its misprinted as 6..

very useful and simple steps to understand sir. but one correction is needed- IN SSG calculation, you have to divide by 4-not with 6 sir.
can you correct it !

sir,but how we get R as 4 sir?

We cant even understand how to interpret data for one way, that table in the beginning of the vid.
Thnkuuu so much again with all my heart ❤ur video content has made my project work complete 💯😅 explanation is too good
Most welcome 😊
While computing the sum of squares within groups, do you divide by the number of groups (=6) or by the number of individual group observations (=4), which is the same for all 6 groups!?
By 4 (number of elements in groups)
Your computation for SSG will turn out to be negative if you divide by 6.
As per your final.number 16.33 that is feasible only when you divide by 4.
@@RiteshDubey84 but you can see he divided it by 6?
