• put your data in numerical order
• add up every piece of data
• divide by the number of pieces of data there were
  

• arange your data in numerical order
• cross out one number on both sides till you find the middle
• if there are two numbers add them up and divide them by two

mode

• the most common number in a set of data

• arrange your data in numerical order
• subtract your lowest data from your highest data

• arrange data in ascending order.


• the sum of all data divided by the number of data.


• with an oulier the mean is less accurate

Median

• arrange the data in ascending order.


• find the middle number


• if there are 2 middle numbers you find the mean of them.


• great to use if theres no outlier.
  

Mode

• arrange the data in ascending order.


• find the data that occurs the most in the set of data.


• you can have more than one mode.


• you can have no mode.

Range

• arrange the data in ascending order.


• subtract the smallest data from the biggest data


• Large Range = Outlier

Here is the Video I found on MMM

• Arrange the data in ascending order.
• The sum of numbers divided by how many numbers there are in a data .
• With an outlier the mean is less accurate.

Median :

• Arrange the data in ascending order.
• The middle number in a set of data.
• Find the middle number.
• If there are 2 middle numbers you find the mean of them.
• Great to use if there's an outlier.

Mode :

• Arrange the data in ascending order.
• The most frequently used number in the data.
• Data that appears the most.
• More than one mode.
• You can have no mode.

Range :

• Arrange the data in ascending order.
• Subtract the smallest data from the largest data

• Arrange data in ascendeing numerical order.


• Divide the sum of all of the numbers in that set of data by how many numbers there are.
  
• With an outlier less accurate..

• Arrange data in ascending numerical order.
  
• Find the middle number by crossing of the end numbers until you have one or two numbers left.
  
• If you have two numbers left, add both of those numbers together and then divide that number by two.


• If you have one more number left, you have got your median.
  
• Great to use if there is an outlier.

• Arrange data in ascending numerical order.
  
• You can have more than one mode or no mode at all.

Range

• Arrange data in ascending numerical number.
  
• Subtract the largest piece of dat from the smallest.
  
• If you have a large range there is a posibility that you have an outlier.

This is a video that I found about mean, medain, mode, and range.

• ascending order



• sum of all the data
  


• number of data
  

median

• ascending numerical order




• the middle number




• found in the middle

mode

• ascending order



• most common number



• number that shows up the most
  
  

range

• ascending order




• added up numbers




• divided

Here is a movie about mean median mode

• the sum of all data devided by the number of data
• outlier effects the outcome

This is a link about the mean

Median

• the middle number of a set of data
  
• there are two middle numbers find the mean of the numbers

Mode

• the number that shows up the most
  

there can be more than one or no mode

This is a link about mode

Range

• the largestest data minus the smallest data
  
• an outlier effects the outcome

• The sum of a set of values divided by the number of values in the set.
• Arrange the data in ascending order.

• The middle number in a set of data after have been arranged in order.
• The median is a measure of central tendency that describes the middle of the set
  of data.

• The mode is the most frequently occurring value in a set of data.
• The item in a list of numbers that appears most often is the mode. For example:

• The range of a set of data is the difference between the highest and lowest values in the set.
• Range is obtained by taking the difference of the maximum and minimum values of a given data set.

MEAN
Definition:
-Arrange the data in ascending order
-Add all the data and divide by how many pieces of data there are
-When an outliers are present, it makes the mean less accurate MEDIAN
Definition:
-You must arrange the data in ascending order
-Find the number in the middle number
-If there are 2 numbers in the middle, add them, then divide by 2
-Using the median is appropriate if there are outliers present because it gets rid of them

MODE
Definition:
-Arrange the data in ascending order -
The most frequently occurring number in a set of data
-There can be more than one mode
-There can be no mode at all

RANGE
Definition:
-You must arrange the data in ascending order
-Subtract the smallest data from the biggest data
-Range tells you if there are outliers
-The smaller the range, the less chance there is of being outliers present

Here is a video of Mean Median and Mode...
