![]() ![]() Find the Z- score animated demonstrations or click here Using the Z-table Knowing the number of standard deviations from the mean gives us a reliable way to know how likely a score is for a population.Ģ There is a table of Z-Scores that gives the corresponding areas or probabilities under the curve. Start this section by reviewing the first two topics in the above outline on the web page. Just move the decimal place to the right two places to turn the decimal into a percentage. Some examples require that you convert the decimal value to a percentage. Lesson 7 Z-Scores and Probability Outline Introduction Areas Under the Normal Curve Using the Z-table Converting Z-score to area -area less than z/area greater than z/area between two z-valuesġ Lesson 7 Z-Scores and Probability Outline Introduction Areas Under the Normal Curve Using the Z-table Converting Z- score to area -area less than z/area greater than z/area between two z-values Converting raw score to Z- score to area Converting area to Z- score to raw score Introduction/Area Under the Curve Please note that area, proportion and Probability are represented the same way (as a decimal value).
