<h4>Chapter 32: <Big data> <big data=""></big></h4>

<big data=""> r=?(Xi -X)(Yi-Y)/√?(Xi-X)2/(n-1)*/√?(Yi-Y)2/(n-1).
</big>
<big data=""> “What is wrong with this equation?”
</big>
<big data=""> Woosung stood up and approached the whiteboard. As he added to the equation, he exined.
</big>
<big data=""> “It is an equation to find the corrtion coefficient, but you used a slightly different version.”
</big>
<big data=""> r=?(Xi -X)(Yi-Y)/(n-1)/√?(Xi-X)2/(n-1)*/√?(Yi-Y)2/(n-1).
</big>
<big data=""> Woosung wrote without hesitation. Oh Juhoon gave out an unhappy nod as a response.
</big>
<big data=""> “You’re right. I guess you’re…good at stats too.”
</big>
<big data=""> “It’s the foundation of data analysis. I try to keep up with it.”
</big>
<big data=""> Woosung’s knowledge was impressive. Cha Yeoreum couldn’t hide her surprise.
</big>
<big data=""> ‘Oh Juhoon has a PhD in Statistics…’
</big>
<big data=""> An expert in the field asked a question, and Woosung answered it without a second thought. She couldn’t understand the equation, but she knew it was not an easy question. Kwak Jungwook felt the same.
</big>
<big data=""> “Wow, is there anything you can’t do, Woosung?”
</big>
<big data=""> Yoon Gihwanughed and answered.
</big>
<big data=""> “Hahaha. Our newbie can do anything.”
</big>
<big data=""> “I believe that.”
</big>
<big data=""> The mood lightened in the room. Woosung grinned and answered.
</big>
<big data=""> “I honestly don’t know if there is anything I can’t do.”
</big>
<big data=""> Kwak Jungwook asked with widened eyes.
</big>
<big data=""> “What?”
</big>
<big data=""> “Haha. I’m just kidding. It’s a joke.”
</big>
<big data=""> Woosung looked at Kwon Taegyun and asked.
</big>
<big data=""> “So what do you think? If you agree to a seminar, I will give you every detail you need.”
</big>
<big data=""> Kwon Taegyun looked at Oh Juhoon again. He was the actual brain behind this project so his opinion mattered.
</big>
<big data=""> Nod.
</big>
<big data=""> Oh Juhoon nodded. It was necessary. Kwon Taegyun closed his eyes tightly and scratched his forehead. When he remained silent, Kwak Jungwook spoke out.
</big>
<big data=""> “PM Kwon, I don’t think it’s a bad idea. Why don’t we just go ahead with it?”
</big>
<big data=""> At Kwak Jungwook’s urging, Kwon Taegyun had no choice but to agree.
</big>
<big data=""> “Fine.”
</big>
<big data=""> A tense atmosphere filled the room once again. Woosung had nothing more to say, so he stood up and left, followed by Yoon Gihwan and Kwak Jungwook. Everyone from Daeyang System, however, remained silent in the room.
</big>
<big data=""> ***
</big>
<big data=""> After the meeting, Kwak Jungwook went back to the headquarters. The general manager was very interested in this project, so letting him know of every major event was critical.
</big>
<big data=""> When he entered the room, Kwak Jungwook informed Jo Youngsuk.
</big>
<big data=""> “Sir, Woosung Kang was right. He exined every point logically and Daeyang couldn’t deny anything.”
</big>
<big data=""> “So he was right…”
</big>
<big data=""> Kwak Jungwook remembered Woosung’s words.
</big>
<big data=""> “He used them of not even having a clear project goal.”
</big>
<big data=""> “And Daeyang epted it?”
</big>
<big data=""> Jo Youngsuk couldn’t believe it.
</big>
<big data=""> “Do you remember Oh Juhoon who wrote the proposal report?”
</big>
<big data=""> Jo Youngsuk nodded.
</big>
<big data=""> Oh Juhoon.
</big>
<big data=""> He received his PhD in statistics from the University of Seoul. He gave an expert and impressive presentation of his project.
</big>
<big data=""> “Even Oh Juhoon agreed with Woosung. He approved Woosung’s seminar.”
</big>
<big data=""> “So a newbie who graduated from Songwon University convinced an expert with a PhD from University of Seoul?”
</big>
<big data=""> “Woosung was impressive. I am beginning to wonder if there is anything he can’t do.”
</big>
<big data=""> “I want him. I need someone like him beside me…”
</big>
<big data=""> “Would you like me to offer him a job on your behalf?”
</big>
<big data=""> Jo Youngsuk shook his head.
</big>
<big data=""> “No. I need to do it myself in person. Please arrange a meeting with him.”
</big>
<big data=""> “Ok.”
</big>
<big data=""> Kwak Jungwook nodded and left the room. Jo Youngsuk’s eyes sparkled expectantly.
</big>
<big data=""> ***
</big>
<big data=""> Yoon Gihwan, now more curious than ever, looked at Woosung.
</big>
<big data=""> “When did you have the time to study statistics?”
</big>
<big data=""> “I thought I told you before. I am studying both mathematics and statistics.”
</big>
<big data=""> “But you didn’t tell me you’re good at it.”
</big>
<big data=""> “Well, fair enough. I’m telling you now. I’m awesome at it.”
</big>
<big data=""> “…what?”
</big>
<big data=""> Yoon Gihwanughed.
</big>
<big data=""> “I am studying college mathematics and linear algebra again as well. I didn’t realize how good I am at them.”
</big>
<big data=""> These were subjects he used to hate when he was still at school. At best, he could get a B grade at the time, but now, things were different. Death has given him a better brain and stronger determination.
</big>
<big data=""> Yoon Gihwan smiled and answered.
</big>
<big data=""> “Alright, you’re great. I admit it.”
</big>
<big data=""> Woosung smiled as well.
</big>
<big data=""> “Haha, I’m kidding.”
</big>
<big data=""> Yoon Gihwan patted Woosung’s shoulder and asked.
</big>
<big data=""> “By the way, it’s Friday today. Do you have any ns after work? Let’s go for a drink.”
</big>
<big data=""> “Please don’t use me because you’re lonely.”
</big>
<big data=""> Yoon Gihwan grunted.
</big>
<big data=""> “Huh. What are you talking about?”
</big>
<big data=""> “Haha. Drink with Manager Park. I need to finish up preparing for the Microsoft seminar tomorrow.”
</big>
<big data=""> “Is that already tomorrow?”
</big>
<big data=""> “I know. Time flies.”
</big>
<big data=""> Woosung looked out the window. Winter was almost over and spring was around the corner.
</big>

</big>
<big data=""> Gangnam was now the center of Seoul.
</big>
<big data=""> The Microsoft developer conference was taking ce at Daeyang hotel ced at the center of Gangnam.
</big>
<big data=""> Saturday.
</big>
<big data=""> The road was busy, but he still took the car he received from Jang Gwangchul.
</big>
<big data=""> “Here we go.”
</big>
<big data=""> The ride was smooth and quiet. He could feel the eyes of the other drivers on the road glued at him and his ride.
</big>
<big data=""> It was 2008. Luxury foreign cars weren’t amon spectacle seen in South Korea yet.
</big>
<big data=""> “I love Benz.”
</big>
<big data=""> It was indeed an amazing car.
</big>
<big data=""> “I should thank him for this present.”
</big>
<big data=""> Jang Gwangchul.
</big>
<big data=""> He felt appreciative and he knew this was what Jang Gwangchul wanted him to feel.
</big>
<big data=""> “You will reach your destination in 100m. Please drive safe.”
</big>
<big data=""> “You will reach your destination in 100m. Please drive safe.”
</big>
<big data=""> “You will reach your destination in 100m. Please drive safe.”
</big>
<big data=""> The built-in navigation informed Woosung.
</big>
<big data=""> ***
</big>
<big data=""> Yoon Chanjong arrived at the Microsoft conference with his colleague Park Jonghyun. Many luxury cars arrived, one could notice the envy in the way Park Jonghyun gazes at them.
</big>
<big data=""> “Hey, when will the others arrive?”
</big>
<big data=""> “In 10 minutes. Yeoreum will be here too so make sure you watch what you say.”
</big>
<big data=""> “Hey, I’m not that stupid. By the way, do you know any girl around? Come on, you can introduce me.”
</big>
<big data=""> “Phew, no. You don’t even have a job.”
</big>
<big data=""> “I keep telling you, it’s by choice. I’ll get one very soon.”
</big>
<big data=""> “Jonghyun, I’m telling you as a friend…”
</big>
<big data=""> Park Jonghyun’s ears were closed as something distracted his attention. He turned around and pointed at a car.
</big>
<big data=""> “Hey, look. It’s a Benz S-ss 350L. I heard it’s worth over 100,000 dors. It’s the price of an apartment.”
</big>
<big data=""> Yoon Chanjong turned around as well. His current annual sry was less than 30,000 dors. Even if he saved everything, it would take him years to afford a car like that.
</big>
<big data=""> “I can’t believe how expensive it is.”
</big>
<big data=""> “It’s not just the price of the car. Maintenance costs a fortune too. Insurance, taxes, and gas…”
</big>
<big data=""> Yoon Chanjong licked his lips. He thought he made it by getting a job, but it was only the beginning.
</big>
<big data=""> Park Jonghyun continued.
</big>
<big data=""> “I would love to be rich. Drive fancy cars and date gorgeous women would be my dream.”
</big>
<big data=""> As they chatted, a car stopped nearby, and the driver stepped out.
</big>
<big data=""> “Huh?”
</big>
<big data=""> “W…Woosung?”
</big>
<big data=""> “It’s him, and that’s the car he got as a present at the graduation ceremony!”
</big>
<big data=""> Woosung didn’t see them. He handed the key to the valet and walked into the hotel. It was very crowded due to the conference. Park Jonghyun ran to catch up to Woosung.
