A graphic labeled "Statistical Inference." There are two circles with arrows pointing to each other. The green one is on the left and labeled "Population," whereas the pink circle is on the right and labeled "Sample." In the same green as the green circle, the word "Parameter" is written nearby, defined as "A summary measure associated with the population (usually unknown)." In the same color of pink as the pink circle, the word "Statistic" is written nearby and defined as "A summary measure associated with the sample (calculated from an observed sample)." Above the circles is text reading "Step 1: Take a sample." In the pink circle, there is text reading "Step 2: Sample shows a relationship." Beneath the green circle, there is text reading "Step 3: Does that mean there is a real relationship in the population? Or was the relationship in the sample just due to chance?" Beneath this is a green arrow pointing to the left, under which it reads, "We can only infer back to the population if the sampling method is unbiased.
