The phrase refers to a calculating device permitted during the Advanced Placement Statistics examination. This device must perform statistical calculations. For example, it should readily calculate summary statistics (mean, standard deviation), conduct regression analysis, and determine probabilities from distributions such as the normal and t-distributions.
Access to a capable calculating device is critical for efficient problem-solving during the assessment. It reduces the time spent on manual computations, allowing candidates to focus on statistical concepts and interpretation. Previously, reliance on statistical tables was necessary; however, the allowance of specific calculators streamlines the process, better mirroring real-world data analysis practices.
