If your organization is able to dedicate resources to running controlled experiments, you may be able to determine causation between variables. The key in diagnostic analytics is remembering that just because two variables are correlated, it doesn’t necessarily mean one caused the other to occur. Alternatively, if two variables are negatively correlated, one variable goes up while the other goes down. If two variables are positively correlated, it means that as one goes up or down, so does the other. If two or more variables are correlated, their directional movements are related. When exploring relationships between variables, it’s important to be aware of the distinction between correlation and causation. The hypothesis directs your analysis and serves as a reminder of what you’re aiming to prove or disprove. When conducting diagnostic analytics, hypotheses are historically-oriented (for example, “I predict this month’s decline in sales was caused by our product’s recent price increase.”). Hypotheses can be future-oriented (for example, “If we change our company’s logo, more people in North America will buy our product.”), but these aid predictive or prescriptive analytics. Having a hypothesis to test can guide and focus your diagnostic analysis. Hypothesis testing is the statistical process of proving or disproving an assumption. There several concepts to understand before diving into diagnostic analytics: hypothesis testing, the difference between correlation and causation, and diagnostic regression analysis.

Diagnostic analysis can be done manually, using an algorithm, or with statistical software (such as Microsoft Excel). It can be viewed as a logical next step after using descriptive analytics to identify trends.
