# How do you find the z-score to the left?

## How do you find the z-score to the left?

Area shaded to the left of a z-score (z is greater than the mean).

1. Step 1: Split your given decimal into two after the tenths decimal place. For example, if you’re given 0.46, split that into 0.4 + 0.06.
2. Step 2: Look up your decimals from Step 1 in the z-table.
3. Step 3: Add 0.500 to the z-value you just found in step 2.

What is the area under the curve to the left of Z?

The total possible value that can be under the curve is 1.00. This means that if the whole population fell under the curve, the area would be a value of 1.00. The area to the left of the z score represents the total area under the curve that is left to the z score.

### What is the area to the left of Z 0?

The area to the right of Z=0 is (2) the same as the area to the left of Z = 0. This is because Z = 0 is the point of symmetry in a standard normal curve.

What is on standard normal table?

The standard normal distribution table is a compilation of areas from the standard normal distribution, more commonly known as a bell curve, which provides the area of the region located under the bell curve and to the left of a given z-score to represent probabilities of occurrence in a given population.

#### How do you find the area to the left of Z in Excel?

Excel solution “Find the area under the normal curve to the left of .” =NORMSDIST(z-score) gives you the area to the left of that z-score. “Find the area under the normal curve to the right of .” To get area to the RIGHT of a certain z-score, tell Excel to subtract 1 minus the area to the left of that z-score.

What is on Z table?

A z-table, also called the standard normal table, is a mathematical table that allows us to know the percentage of values below (to the left) a z-score in a standard normal distribution (SND). When the mean of the z-score is calculated it is always 0, and the standard deviation (variance) is always in increments of 1.

## What is the area of the normal curve to the left of the mean?

The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. The area under the normal distribution curve represents probability and the total area under the curve sums to one.
