App::St(3)

💖 App::St 💖

okay so bestie, welcome to App::St — which lives in the perl manual pages as App::St(3) btw, in case you were wondering where we're at. this is the whole Simple Statistics situation, and ngl it's lowkey iconic. 🎀

---

✨ NAME ✨

App::St — literally just Simple Statistics. that's the vibe. that's the whole thing. 💅

---

🌸 DESCRIPTION 🌸

okay so here's the tea: App::St gives you the core functionality of the st-console application. like, the whole engine underneath. the main character energy of the stats app. ✨

---

🦋 SYNOPSIS 🦋

here's how you actually use it, bestie:

use App::St;

my $st = App::St->new();

while (<>) {
  chomp;
  next unless $st->validate($_);
  $st->process($_);
}

print $st->mean();
print $st->stddev();
print $st->sterr();

slay. feed it numbers, it validates them, it processes them, and then you just... ask it for the stats you want. obsessed. 🫶

---

👑 METHODS 👑

okay so here's the full roster, no skips, every single one:

• new(%options) — makes you a shiny new object. takes %options too. main character constructor behavior fr fr. ✨
• validate($num) — vibe checks $num and tells you if it's valid. use it before you let anything in. 🧚
• process($num) — feeds $num into the mix so it counts toward your stats. 💜
• N — the count. how many. the number of numbers, bestie. 💀
• sum — adds it all up. the total. 🍓
• mean — the average. you know this one. 💅
• stddev — standard deviation, the classic. 🔥
• stderr — standard error. not the file descriptor, the statistics one, don't get it twisted. 😭
• percentile=<0..100> — percentile, and the range is <0..100> exactly, keep it in those bounds bestie. 🌈
• quartile=<0..4> — quartile, range <0..4>, so like q1 through q3 territory plus the edges. ⭐
• min — the smallest one. the little guy. 🥺
• q1 — first quartile. 🌸
• median — the middle. the actual center of the situation. 👑
• q3 — third quartile. 🦋
• max — the biggest one. the icon. 💖
