Finding critical value on ti 84.

A z-score tells us how many standard deviations away a given value is from the mean. The z-score of a given value is calculated as: z-score = (x – μ) / σ. where: x: individual value. μ: population mean. σ: population standard deviation. This tutorial explains how to calculate z-scores on a TI-84 calculator.

The TI 84 is more feature-rich, as it has several built-in functions for mode, median, and mean. These functions are only sometimes apparent to students, however. The program does much more than find the critical value for a given area. Suppose a researcher is conduct a two-tailed hypothesis test using α = .05. What is the z-critical value that corresponds to this alpha level? To find this critical value, we can use the formula 1 – α/2. In this case, we will use 1 – .05/2 = .975 for the probability: The answer is z = 1.96. Example 3: Z-Critical Value for Cut-Off Scores
