How to calculate minimal sample size for a paired samples t test without t score or raw scores from a previous study?

2021.10.19 23:21 IsPepsiOkaySir How to calculate minimal sample size for a paired samples t test without t score or raw scores from a previous study?

Hi,
I want to do a study on auditory cloosed-loop stimulation's effect on memory consolidation. Previous studies have been done on this.
I'm trying to calculate an effect size in Cohen's d since GPower, the software I use to calculate minimal sample size I should use, requires a Cohen's d value to do that.
However, while reading the article I'm trying to calculate the effect size from (Ngo et al., 2013), I noticed that they used a paired samples t-test to test the retention rate difference between stimulus vs. sham condition.
Since they don't provide their t's value, I cannot transform the t into Cohen's d. Since they don't provide the raw scores of every participant, I can't run the paired samples t-test.
What should I do in this situation ?

2021.10.19 23:21 Jolly-Ad-304 Can I get into the Navy as a Officer with a 41 on the OAR

I want to join the Navy as a OffIcer and a SWO. I just got my masters in education and been coaching division 1 college basketball for the pas two years. I also played division 1 college basketball from 2013-2017. I graduated with a 3.47 gpa in my masters program. Today I took the OAR for the second and got a 41. My Recruiter said that we will have to use a waiver to turn in with my application to help me get in. But also said he think I will have a good chance with my resume of playing college basketball and coaching. Also with me having a high gpa and master degree. I got a letter of rec from the Vice President of student affairs from the university I played and coach at. If there’s anything I should add in my package to help me be as competitive as possible please let me know.

2021.10.19 23:21 CrystalDragon81 Today I got blocked for telling someone I was Demi.

So, I met this guy on tinder a while back, like 3 weeks or so. And from the VERY beginning I made it extremely clear that I was demi and I won’t develop feelings for quite a while. He was fine with it. Skip to now, he messages me telling me he’s super anxious because he felt like I was being distant (which to his credit, I was. He was pretty narcissistic and literally said “I can get anyone to do anything I want cause I know psycho manipulation”. So I did kinda distance myself)
but anyway I told him that I did think he was a cool person, I just would rather stay friends for the foreseeable future, cause I’m demi and romantic feelings aren’t a guarantee.
He immediately goes “ok well I’m not going to cuddle you again from now on. Also please don’t hug me, hugs make me incredibly uncomfortable and the only reason I tolerated them was because you were comfortable and warm. This has to be strictly platonic from now on.” As if hugs and cuddles aren’t platonic??
Anyway, he cuts the convo short and goes to bed. Next day rolls around and I basically just told him that I didn’t like the total 180 his personality did and I think we should stop hanging out. And he instantly blocked me. Dude went from “I’m falling hardcore for you.” To blocking me instantly.
TLDR: guy turned into a “nice guy”, changed personalities, and blocked me as soon as I told him it would take me a long time to develop feelings, despite me literally explaining demi when we first met.

2021.10.19 23:21 ixinho Let's get real, no one will ever get this trophy, meaning no one will ever get platinum on PS4/PS5. Why does this trophy exist? Isn't softcore lvl 99 trophy already crazy enough? Someone needs to change this, otherwise no one will ever "complete" D2R on playstation.

my science teacher sucks. first, he doesn’t teach us, he just gives us worksheets that we don’t know how to do therefore we have to google the questions and when it comes to a quiz we don’t know how to do the stuff
second, he never gives us graded work therefore we can barely pull our grades up and when he does, he doesn’t put it in the grade book

2021.10.19 23:21 evasativaa Help! I get itchy when I smoke weed!

Okay so I’ve been smoking weed since I was 16 (I’m 20 now) around 5/7 days a week if I was to put a number on it. Over the past 9 months or so whenever I smoke my throat (right at the back where it is connected with my ears, I can almost itch it through my ear???) and the waterlines of both eves itchy (kind of like how hayfever feels). Anyone know why this may be happening, is my throat finally properly irritated by the smoke? Or am I allergic to it or something? Can you develop allergies or am I being stupid????
