Not All z-Tables Are Created Equal
A quick search on the web shows that some z-Tables are better than others.
Sometimes we want the area above the z-score and other times the area below. Sometimes we need to look up a p-value using a positive z-score and other times a negative . Maybe we want to find the percentage or maybe we want it as a decimal. In fact, often we need to look up the z-score based on the given area under the curve value.
When students try to understand how one z-Table works, it doesn't seem to help them understand how they all work. Every z-Table out there has its own system for presenting normal distribution data.
This very Simple z-Table Lookup helps students learn exactly how all z-Tables relate to one another. One single page lets you see at a glance the different areas under the curve for both positive and negative distances.
