Does Statistics For Dummies Explain Standard Deviation Clearly?

An apocalypse driven by natural disasters. Survival of the fittest. Typhoons, floods, deadly cold, scorching heat, earthquakes, tsunamis, insect plagues, acid rain… After struggling through three years of the apocalypse, Nicole Floyd met a brutal death. Miraculously, she woke up and found herself three days before it all began. Nicole seized the advantage to reclaim her storage space, flipping the switch on full-on stockpiling mode. She shopped until she ran out of money, and her storage was packed tight. She also looked for the dog that had saved her life once before. She sharpened her knives, stacked her supplies, and took care of unfinished business. She paid back every debt, whether owed in blood or in kindness. And then, disaster struck. Her right hand gripping a knife and her left stroking the dog, Nicole pressed on through the ruins of a world without order or morals.

A month before the SATs, I, Jenny Reid, could see my score. Literally. It was just floating right above my head. But there was a catch. Every time I cracked open a prep book, my score would drop by ten points. But if I skipped a day of school? It jumped right back up by ten. So, I played the system. For a whole month, I barely lifted a finger. And on the day of the test, the number glowing over my head was a solid 1560. When the scores finally dropped online… I'd scored a 500. And the 1560? That was my little sister Patricia's score. My parents lost it. As punishment, they got me a grueling night-shift job at a local electronics factory. That first night, a bunch of guys I'd never seen before cornered me in the parking lot and beat me half to death. Fading in and out of consciousness, I heard my sister's voice right by my ear. "You just had to one-up me, didn't you? Thought you were so smart… but you never figured out I was the one controlling that number over your head." The truth hit me like a physical blow. The score had been her trick all along. I opened my eyes—and I was back. One month before the SATs. The number above my head read exactly 1300. "Hey," my sister said, all fake sweetness. "Want to study together tonight? We can go over the practice tests." I looked at the stack of papers in my own hands. Without a word, I pulled out my lighter and set them on fire right there in the driveway. "Exams are coming," I said, watching the flames. "I'm not studying." My score ticked up to 1310. My sister's face was this perfect mask of disappointment, but the second I turned away, I caught the sly smile she couldn't quite hide. She had no idea… the real performance, the one I'd been rehearsing just for her, was finally about to begin.

When the SAT scores are out, I've scored 400 out of 1600. That's because I never wrote anything on my exam papers. My mom goes crazy, whereas my younger sister, Melinda Bolton, bursts into tears. But I just laugh at them instead. In my previous life, Melinda had formed a pact with the score-swapping system. That was how she swapped our SAT scores. She became the top scorer that all prestigious universities fought to recruit. I, the valedictorian of my year, not only got into a trade school, but I also got expelled from my previous high school. Melinda had the gall to comfort me. "Didn't you call yourself a genius, Melissa? Trade schools are very popular right now. In the future, you'll secure a job at a factory out there!" In this life, I spend my exam hours sleeping in my seat the whole time. Melinda wants to swap her scores, right? Then, let's do it properly!

My father was a senior HR executive. He used KPIs to define my life. "Rank top ten in your grade, and I'll give you a B, with a bonus of 250 dollars. "Place in a state-level competition, and you'll get an A, with a bonus of 500. "If your SAT score hits Ivy-level, I'll give you an S+ and a 5,000-dollar year-end bonus." I studied as if my life depended on it, and in the end, I got the acceptance letter. My father slapped a contract down in front of me instead. "Congratulations on onboarding into the next phase. Starting today, your allowance will be structured as base salary plus performance plus attendance bonus. "Base pay is 250 dollars a month, enough to keep you from starving. "To prepare you for a high-pressure work environment, I’ll conduct random inspections. Fail, and your pay gets docked." When I ran a 104°F fever, he cut my attendance bonus, saying my physical resilience didn't meet standards. When I forgot to submit a weekly report because I was buried in schoolwork, he froze all my money. To stay alive, I went behind his back and sold blood at the hospital. At the end of the semester, I held my transcript and scholarship certificate, thinking I had finally earned the highest rating. But my father looked at me without a trace of warmth. "Your S+ bonus has been reallocated. The company decided to invest it in your brother, Harry. He has more potential." I looked at the 100-dollar "consolation prize" he handed me and laughed. So in his company, I didn't even qualify as an "outstanding employee."

“Who the hell changed the screw tolerance by 0.007 mm?” “I did. Is there a problem?” Kimmy Zabel, our department’s “good-luck charm” and full-time slacktivist, did not even look up from her compact mirror, where she was carefully applying lip gloss. “It just didn’t look right, so I tweaked it. Do you really have to yell at me?” The production line had been running on the wrong spec for twenty-four hours. I hit the emergency stop. Keeping my voice steady took some effort. “These parts no longer meet export standards. If we miss tomorrow’s shipment, even a month of overtime wouldn’t cover the penalties.” “It’s one tiny number. You’re being so dramatic!” Kimmy snapped her makeup case shut. “Anyway, it’s New Year’s Eve. I’ve got a date. I’m not staying here to suffer with you people.” Before she even reached the door, I gestured to the staff to pull the shutters down. “For precision components like these, one number translates into a million-dollar loss. You can take these defective units and explain them to the regulators.”
