# How do you find standard deviation from height?

## How do you find standard deviation from height?

If **height** is converted to a **standard deviation score** (SDS)—the number of **standard deviations** above or below the mean **height** for age and sex—then the age and sex effects are adjusted for and the regression **equation** simplifies to: child **height** SDS = coefficient × midparental **height** SDS (**Equation** 1).

## What is the height of a normal distribution?

The **height** (ordinate) of a **normal curve** is defined as: where μ is the mean and σ is the standard deviation, π is the constant 3.

## What is a high standard deviation?

Low **standard deviation** means data are clustered around the mean, and **high standard deviation** indicates data are more spread out. A **standard deviation** close to zero indicates that data points are close to the mean, whereas a **high** or low **standard deviation** indicates data points are respectively above or below the mean.

## Is Sx the standard deviation?

The symbol **Sx** stands for sample **standard deviation** and the symbol σ stands for population **standard deviation**. If we assume this was sample data, then our final answer would be s =2.

## What is the standard deviation of a data set?

**Standard deviation of a data set** is the square root of the calculated variance of a **set** of **data**. The formula for variance (s2) is the sum of the squared differences between each **data** point and the mean, divided by the number of **data** points.

## Which histogram depicts a higher standard deviation?

Histogram B

## What does the S mean in statistics?

standard deviation

## Is variance standard deviation squared?

The **standard deviation** is the **square** root of the **variance**. The **standard deviation** is expressed in the same units as the mean is, whereas the **variance** is expressed in **squared** units, but for looking at a distribution, you can use either just so long as you are clear about what you are using.

## What is difference between variance and standard deviation?

Key Takeaways. **Standard deviation** looks at how spread out a group **of** numbers is from the mean, by looking at the square root **of** the **variance**. The **variance** measures the average degree to which each point differs from the mean—the average **of** all data points.

## Why is standard deviation square root of variance?

**Standard deviation** (S) = **square root** of the **variance** Because of its close links with the mean, **standard deviation** can be greatly affected if the mean gives a poor measure of central tendency. **Standard deviation** is also influenced by outliers one value could contribute largely to the results of the **standard deviation**.
