Stats: Finding Z-value Given the Probability - YouTube
WebThe probability of an observation having a z-score between 0.40 and 0.65 is 8.675%. Using only simple math and a z-table, you can easily find the probabilities that you need! Alternatively, use the Empirical Rule to find … WebThe z-score allows you to compare data from different samples because z-scores are in terms of standard deviations. A positive z-score means the data value is higher than average. A negative z-score means it's lower than average. You can also determine the percentage of the population that lies above or below any z-score using a z-score table. tough old lady
