Check out the awesome, original artwork! One bird flies left while the whole flock goes right - that's your classic outlier in action! Rebel bird is definitely not following the flock mentality! 🐦📊

Variance measures how spread out your data points are from the average! Think of it like measuring how messy your friend group is - low variance means you're all pretty similar, high variance means someone's always the weird one. Sorry, Jessica! 📊

SwiftStats StatsShort: ✅ Standard deviation = How spread out your data is from the mean ✅ Small SD = Data clustered together, Large SD = Data scattered ❌ Hard to interpret alone (what does "SD = 5.2" mean? 🤷‍♂️) ❌ Also sensitive to outliers (one extreme value inflates all)

SwiftStats StatsShort: ✅ Box = Middle 50% of your data (Q1 to Q3) ✅ Line in box = Median, whiskers = data range, dots = outliers ❌ Looks simple but hides data shape (bimodal distributions look normal 📊) ❌ Can't see sample size (1000 vs 10 data points look identical)

SwiftStats StatsShort: ✅ Scatterplots = Show relationship between two variables (i.e., correlation) visually ✅ Correlation = Measures strength of linear relationship (-1 to +1) ❌ Correlation ≠ causation = Ice cream sales correlate with drownings 🍦🏊‍♂️ (both in summer)

Business consultants who don't know stats are just expensive guessers! Basic statistics help them spot real trends, avoid fake patterns, and give advice that actually works. Your company deserves more than fancy PowerPoints! 💼📊

AI uses regression analysis to find patterns and probability theory to make predictions! It's like teaching computers to connect the dots and guess what comes next. 🤖📊

SwiftStats StatsShort: ✅ Z-score = How many standard deviations away from the mean ✅ Standardizes everything = Compare apples to oranges ❌ Assumes normal dist = Wont work well with skewed data 📊 ❌ Needs context = "Z = 2.1" means nothing if you don't know normal 🤔
