Median:The middle number in a data set when the data are put in order; a type of average.





Mode:A type of average; the number (or numbers) that occurs most frequently in a set of data.

Range:In statistics, the difference between the largest and the smallest numbers in a data set.

Here's a video that explains the mean, median, mode, and range :

• Arrange the data in ascending numerical order.
• Add up all the data.
• Divide the sum by how many pieces of data there are.

• Arrange the data in ascending numerical order.
• Cross out the border numbers until you remain with one.
• In the occasion of there being 2 numbers, you add them and then divide by 2.

• Arrange the data in ascending numerical order.
• Find the most occurring number.
• Note that it is possible to have more than one mode.

• Arrange the data in ascending numerical order.
• Subtract the lowest number from the highest number.

• Arrange the data in ascending numerical order.
• The mean is the sum of all data
  

• Arrange the data in acending numerical order.
• The median is the number that is in the middle
• If there is two numbers in the middle number between those two numbers.

• Arrange the data in ascending numerical order.
• The mode is the number that shows up often.

• Arrange the data in ascending order.
• The range is when you subtract the smallest piece of data from the largest piece of data.
  

Mean

- Arrange data in ascending order.(1, 1, 3, 4, 4)
- Add the set of data together. (1+1+3+4+4=13)
- Take the sum of data, and divide it by the numbers of data. (13/5=2.6)

Median

- Arrange data in ascending order. (1, 1, 3, 4, 4)
- Cross out each number on the right and left until one number is left. (1, 1, 3, 4, 4)
- 3 is the middle number out of the data.
(If the numbers of data equal up to an equal number, you must take the last 2, add them together, and divide the sum by 2. 1, 1, 3, 4, 4, 5. 3+4= 7/2=3.5

Mode

- Arrange data in ascending order. (1, 1, 3, 4, 4)
- Found the most occuring number/S. (1, 1, 3, 4, 4)
- 1 and 4 are the mode.
(There doesn't always have to be a Mode. There CAN be more than ONE Mode.)

Range

- Arrange data in ascending order (1, 1, 3, 4, 4)
- Look for the greatest piece of data (1, 1, 3, 4, 4)
- Look for the smallest piece of data (1, 1, 3, 4, 4)
- Subtract the greatest piece of data with the smallest piece of data (4-3=1)

Median: The median is the middle value in a set of data. If there are 2 medians in the middle, add them together and divide by 2.

Mode: The mode is the most frequently occurring number in a set data, there can be more than one mode.
Range: The range is the difference between the largest and smallest values in a set of data.


Here is a video that explains mean, median, mode, and range :

Mode
- arrange the data in ascending order
- most frequently used number in the data
- you can have more then one more or NO mode



Range
-Arrange data in ascending order
-Look for the greatest piece of data
-Look for the smallest piece of data
-Subtract the greatest piece of data with the smallest piece of data

Here is a video that explains MMM.
