Private Finished The Evils of Math

Yuki looked up from his worksheet with relief, honestly glad to be able to interact with someone. He used to have a friend that helped him with maths, but now they weren't around as much. He never really got an explanation for it, but things happened. Life changed.

"Um...hiya. I'm Yuki." He said back, a little nervous. This...this girl was kind of cute. Not that he'd say it out loud. But...yeah. It was nice to see that people were still friendly and stuff - it was kind of out of the blue, though. Yuki didn't think he'd even seen this girl before, but oh well. She was probably another of the many transfer students the academy always seemed to get.

"That'd be great..." He laughed with obvious relief. "I'm really having trouble with these sampling strategies. How do you get stratified sample data here?" He said, pointing to question three.

@Big Jeffe

He nodded, beginning the calculations and going further down the worksheet before carrying on the conversation. Thank the heavens that they were allowed to use calculators in this class. Honestly, Yuki hated statistics, but he saw the point. It was useful to be able to look at different methods of taking data and understanding why different methods had their own merits and drawbacks.

"Right. Question four..." He was glad that there were only five questions in total. "...oh wow. So we're meant to figure out the product moment correlation coefficient... Any ideas?" He asked, looking helplessly at his new maths guru. "I remember that we use our scientific calculators to do it, but past that..." He mused, tapping his pencil on the desk.

Yuki blinked, surprised that Katie didn't seem to know what she was doing this time. Perhaps she wasn't the maths genius he'd originally thought her to be.

"Hmmm...okay." He nodded, mostly to himself. "Thanks for the reminder!" He smiled politely. Yuki supposed that even if Katie didn't know everything, she was at least a brilliant morale booster. After all, who honestly knew everything? Except maybe an Eldritch monstrosity, or someone with access to a magical database of knowledge. Or someone who was constantly connected to the inter--

Okay, clearly he was getting distracted. "Hmm...Katie, do you remember how to get these into statistics mode?" He asked with a sheepish laugh, offering her his Casio calculator. "I thiiiink I might know how to find it from there, but I completely forgot how to get this thing to start a table."

Maybe they still had a chance, if they worked together.

Yuki actually chuckled as Katie got excited about finding the table. "If it was my calculator, I could figure it out, but..." He shook his head. He had no idea. He was way in over his head.

It was time to admit defeat. "I'm going to call the teacher over. Hopefully they'll be able to help us out of our little predicament." He said, laughing a bit. As the teacher came over, he explained their situation and got the refresher he needed. Alright.

"Now question five..." He said, dictating the worksheet's contents. "Explain one drawback of random sampling." Ah. This was his forté - they had covered this last lesson, and Yuki was brilliant when it came to the qualitative side of things. Essays were his strong point.

So he decided to test Katie. "Any ideas?" He said, pulling his best innocently-confused face.

Yuki watched Katie panic and felt a pang of guilt. He knew what it was like to be put through that situation, to feel that fear. To genuinely think that the other person might want you dead for making the tiniest of mistakes.
His fears had been founded back then.

He offered a troubled smile, patting Katie on the head in what he hoped was a reassuring gesture. He found that physical contact normally helped him when he was about to panic. But it only helped from people he knew well. "I don't hate you..." He said, equally softly but putting as much of a reassuring tone into it as he could. "Don't worry. I'll handle this question for the both of us."

And he wrote the answer down, showing Katie his sheet for her to copy.
