The process of determining the standardized score on a TI-84 calculator involves utilizing its statistical functions to convert a raw score into a z-score. This conversion allows for the comparison of data points from different distributions. An example would be converting a student’s exam score to a z-score to assess their performance relative to the class average.
Calculating this value is crucial in hypothesis testing, confidence interval construction, and probability calculations. Its utility stems from standardizing data, enabling comparisons across datasets with varying means and standard deviations. Historically, this calculation was performed manually using tables, but the incorporation of statistical functions into calculators streamlined this process significantly.
