There’s a great moment in John Scalzi’s Redshirts where statistical analysis is mentioned, and it comes down to comparing texts:
“So what you’re saying is all this is impossible,” Dahl said.
Jenkins shook his head. “Nothing’s impossible,” he said. “But some things are pretty damned unlikely. This is one of them.”
“How unlikely?” Dahl asked.
“In all my research there’s only one spaceship I’ve found that has even remotely the same sort of statistical patterns for away missions,” Jenkins said. He rummaged through the graphic elements again, and then threw one onto the screen. They all stared at it.
Duvall frowned. “I don’t recognize this ship,” she said. “And I thought I knew every type of ship we had. Is this a Dub U ship?”
“Not exactly,” Jenkins said. “It’s from the United Federation of Planets.”
Duvall blinked and focused her attention back at Jenkins. “Who are they?” she asked.
“They don’t exist,” Jenkins said, and pointed back at the ship. “And neither does this. This is the starship Enterprise. It’s fictional. It was on a science fictional drama series. And so are we.”
