# What is the mean of the sampling distribution of the difference between means?

**mean of the sampling distribution of the difference between means**is: which says that the

**mean**of the

**distribution**of

**differences between sample means**is equal to the

**difference between**population

**means**.

In this regard, what is the mean of a sampling distribution?

**Mean**. The **mean** of the **sampling distribution** of the **mean** is the **mean** of the population from which the scores were sampled. Therefore, if a population has a **mean** μ, then the **mean** of the **sampling distribution** of the **mean** is also μ. The symbol μ_{M} is used to refer to the **mean** of the **sampling distribution** of the **mean**.

**Distribution**of the

**Sample Mean**. The statistic used to estimate the

**mean**of a population, μ, is the

**sample mean**, .

**If**X has a

**distribution**with

**mean**μ, and standard deviation σ, and is approximately

**normally distributed**or n is large, then is approximately

**normally distributed**with

**mean**μ and standard error ..

Also question is, what does the mean difference tell us?

The **mean difference** (more correctly, '**difference** in means') **is** a standard statistic that measures the absolute **difference** between the **mean** value in two groups in a clinical trial. It estimates the amount by which the experimental intervention changes the outcome on average compared with the control.

The **difference between** the **sample mean and the population mean** (M-μ) is **called**. **sampling** error. A method of **sampling in** which every observation **in the** entire **population** has an equal chance of being selected is **called**. random **sampling**.
