**Mean:** Average.
The amount of a set of data separated by the number of data. (Do not circular
your answer unless directed to do so.)

**Median:** The
center value or the mean of the center two values, once the data is set up in
numerical order. Imagine a median being in the center of a highway.

**Mode:** The value
(number) that seems the most. It is possible to have greater than one mode and
it is possible to possess no mode. If there is no mode-write no mode, do not
write zero (0).

Make use of the mean to explain the middle of a set of data that does not have an outlier.

Use the median to explain the middle of a set of data that does provide an outlier.

Use the mode once the data is non-numeric or when requested to choose the most popular product.

Mean, median and mode are three types of averages. You can find many averages in statistics, however these are, the three most common.

**Mean:** Also
referred to as the average.

The mean is found through adding up all of the given data and dividing from the number of data entries.

**Example: **

The grade 10 math class recently had a mathematics test and the grades were as

**follows: **

78

66

82 464 / 6 = 77.3

89

75

+ 74

464

Therefore, **77.3**
is the mean average of the class.

**Median:** The
median is the center number.

Initially you arrange the numbers in order from lowest to highest, then you locate the middle number by crossing off the numbers till you reach the middle.

**Example:**

use the above data to locate the median:

66 74 75 78 82 89\

as you can see we possess two numbers, there is no middle number.

What do we do?

**It is easy**; we
take the two middle numbers and locate the average, (or mean).

75 + 78 = 153

153 / 2 = 76.5

Therefore, the middle number is **76.5.**

**Mode:**

this is the number that takes place most often.

**Example:**

find the mode of the following data:

78 56 68 92 84 76 74 56 68 66 78 72 66

65 53 61 62 78 84 61 90 87 77 62 88 81

The mode is **78.**

When you get a huge set of data you can find all sorts of methods to mathematically explain the data. The word average is employed a lot. Mean, median and mode are all kinds of averages. Along with range, they help explain the data.

**Mean:** When people
state average they often are talking about the mean. You determine the mean by
adding up all of the numbers in the data after that divide by number of
numbers.

**Median:** The
median is the center number of the data set. Type of like it sounds. To find
out the median you place all the numbers in order (lowest to highest or highest
to lowest) and then select the middle number.

**Mode:** The mode is
the number that seems the most.

**Interesting Facts about Platinum**

Not many chemicals can attack gold, so that’s why it maintains it shine even when buried for 1000’s of years. When compared with other metals, gold is much softer. One can beat 1 gram of gold to a 1 square meter sheet and light would shine via that sheet.

Liquid rock which cools quickly after exposure to the Earth’s atmosphere are fine-grained and known as extrusive. Obsidian is an example of this kind of rock.
