**Sample Mean**. A

**sample**is defined as the subset of the given population. Also, the

**sample**size is usually denoted by n. Thus, the

**sample mean**is defined as the average of n observations from the

**sample**. Moreover, the

**sample mean**is considered to be the estimate of population

**mean**.

Beside this, what is the difference between population mean and sample mean?

**Sample Mean** is the **mean** of **sample** values collected. **Population Mean** is the **mean** of all the values **in the population**. If the **sample** is random and **sample** size is large then the **sample mean** would be a good estimate of the **population mean**. How to calculate a Point Estimate for a **Population Mean**?

Beside above, what is the formula for mean in statistics? The **mean** is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

is sample mean the same as mean?

"**Mean**" usually refers to the population **mean**. This is the **mean** of the entire population of a set. Often, it's not practical to measure every individual member of a set. It's more practical to measure a smaller **sample** from the set. The **mean** of the **sample** group is called the **sample mean**.

What is the formula of median?

If the items are arranged in ascending or descending order of magnitude, then the middle value is called **Median**. **Median** = Size of (n+12)th item. **Median** = average of n2th and n+22th item.
