Ever seen two charts that line up perfectly and thought, “Aha! They must be connected”? This graph shows ice cream sales and shark attacks rising and falling almost in sync. But one doesn’t cause the other—it’s just that both increase when it’s hot out.
Marketers fall for this too—seeing correlations and assuming causation. It’s a classic mistake in data interpretation. Just because your email open rates spike after a redesign doesn’t mean the redesign caused it. Maybe it’s the timing, the subject line, or a seasonal trend.
Show other funny “correlations” to illustrate data pitfalls. Add context labels or draw attention to external factors (like weather).
