Normal Distribution: Calculating Probabilities/Areas (z-table)

Описание к видео Normal Distribution: Calculating Probabilities/Areas (z-table)

This tutorial shows how to calculate areas/probabilities using the cumulative standard normal tables.
For 0 to Z tables:    • Normal Distribution | Mean to Z Table...  
For inverse lookup:    • Normal Distribution:  Finding z and x...  

Steps for calculating areas/probabilities using the cumulative normal distribution table:
1. Translate the score (x) into a z-score:
2. Find the corresponding area from the z-table.
3. i) For less than area/probability, the area in the table is the answer.
ii) For greater than area, subtract area in the table from 1.
iii) For area between, subtract smaller area from larger area.
