MEAN

___Arrange the set of data in ascending order. Add all of the digits and divide the answer by the number of the digit there are when you did it right the answer should be the mean.





MEDIAN

___Arrange the set of data in ascending order. After arranging it in ascending order whatever is in the middle should be the median. If there's two median add them together and divide the answer of how many the median is then the answer should be different from the other digits and the answer of the sum.






MODE

___Arrange the set of data in ascending order. After you arrange it whatever is the number that is most frequently showing is the answer. Sometime there can be no mode.






RANGE

___Arrange the set of data in ascending order. Find the largest and the smallest number in the set of data. Find the difference between those two and whatever is the answer should be the range






Here is a video of Mean, Median, Mode, and Range

Marc's Measures of Central Tendency






------------------------------------------------------------------------------------------------
















  • add all the numbers in the set of data





  • then divide the sum by how many numbers there are
















----------------------------------------------------------------------------------------------





Median:













  • find out the middle number(s) then add them up




  • then divide the sum by 2





  • if there isn't 2 numbers you can add up then the that number is auto maticly the median






















----------------------------------------------------------------------------------------------





Mode :









  • you can find the mode by looking at the set of data and searching for the number that shows up the most

















-----------------------------------------------------------------------------------------------





Range :









  • you can easily find the range by putting the set of data in ascending order





  • then subtract the largest number with the smallest data

Katrina's Measure of Central Tendency

Mean: The mean is the average number. When you add up all the numbers in a set of data, you divide the total by the number of data.

5, 3, 18, 17, 2
5, 3, 18, 17, 2 = 2, 3, 5, 17, 18
2 + 3 + 5 + 17 + 18 = 45 / 5 = 9.
The mean or average of this data is 9.


Median: To locate the median, you have to look for the middle number.

5, 3, 18, 17, 2

5, 3, 18, 17, 2 = 2, 3, 5, 17, 18
Cross out each number on the side until you hit the middle. 2, 3, 5, 17, 18

Mode: The mode is the number that appears the most in a set of data.

5, 3, 18, 17, 2

5, 3, 18, 17, 2 = 2, 3, 5, 17, 18
look for the most common number. In this set of data, there is no mode.

Range: The range is when you subtract the smallest number from the largest number.

Outlier: An outlier is the outcast number in a set of data.
For example, in this set of data, all the numbers are near each other except for the 50.

JP Measures of Central Tendency and pictures

















Mean is when you add up all of the numbers in a set data and divide them by how many numbers there are.

Median:

is the middle set of number in a set of data after all of the numbers have been arranged.

Mode:

is the most frequently occuring number in a set of data.

Range :

is when you subtract the smallest number in the set of data from the largest.

Outlier:

is the most odd number in a set of data for example. 1,2,3,4,20. In that data 20 was the most odd number because it didnt fit with the others.

set of data: 6, 4, 1, 3, 9, 3
Mean is the sum of the added set of numbers.

  • put them in ascending order.

  • you add all numbers in the set of data and you divide it by how many numbers there is you get the mean.

Median is the middle number on a set of data.

  • put the in ascending order again.
  • you look at the middle of all numbers.

Mode is the number that is used most often.

  • always put the numbers in ascending order.
  • a data that is seen in the set of numbers more that one time.



Range is the difference between the highest ad the lowest data on a set of numbers

  • put in ascending order again.
  • take the lowest number and subtract it with the highest number. and the difference between those number is the range.

Katlyn's measure of central Tendacy

Mean



-add up all the numbers is a set of data and divide the sum by the amount of numbers in the data.











-the most repeating number in a set of data












-the number in the middle of the data after the numbers have been put in ascending order . if there are too numbers in the middle you add them together and divivde by 2.















-the largest number subtracted from the smallest number in a set of data.















Tracey's Measure of Central Tendency & Pictures

Mean
First arrange your set of data from least to greatest (ascending order)
Add all of the numbers (set of data)
Once you've found the sum , divide the number by how much numbers there are


Median
First arrange your set of data from least to greatest (ascending order)
Find the middle number, in the set of data
If there is two middle numbers add them together and divide by two


Mode
First arrange your set of data from least to greatest (ascending order)
Find the number that comes up more than once
If there is no number that repeats there is no mode


Range
First arrange your set of data from least to greatest (ascending order)
Find the lowest number and the greatest number, and subtract them from each other

Jessica's Measures Of Central Tendancy

Mean - Arrange the set of data in ascending order. Then add up all the numbers and divide the answer by the number of numbers.

Median
- Arrange the set of data in ascending order. The number in the middle is the median. If there is two numbers in the middle, add them and then divide them by two.

Mode
- Arrange the set of data in ascending order. The number that shows up the most is te mode. There can be no mode if each of the numbers only appears once.

Charissa's Measures of Central Tendency

Mean
The mean is the average of a data set. To find it you have to add up all of the numbers in a data set and divide them by how many numbers there are.
Median
The median is the middle number in a data set. You have to put all of the numbers in ascending order then delete out all the numbers two by two starting from the outside going inwards until you hit the middle.

The mode is the most repeated number in a data set. To find it just put the numbers in ascending (this makes it easier on you) then look for the number which is there the most.


Range
The range is the difference between the highest and the lowest number in a data set. To find it you put the numbers in ascending order and subtract the lowest number from the highest number.

Brendyn's Measures Of Central Tendency With Pictures

Mean -The Average of all numbers in a set

78+66+82+89+75+74 = 464

464/6 = 77.3

Hence, 77.3 is the mean average



Median -The middle of a set of numbers



66 74 75 78 82 89


75 + 78 = 153
153 / 2 = 76.5



Hence, the middle number is 76.5.


Mode - The data that shows up the most



78 56 68 92 84 76 74 56 68 66 78 72 65
65 53 61 62 78 84 61 90 87 77 62 88 81
The mode is 78.

Bobby's Measures of Central Tendency

Mean
  • arrange the data into ascending order
  • add all the numbers, then divide the sum of all data by how many data there are
















Median

  • arrange the data into ascending order

  • then find the middle number

  • if there's two middle number, add it up and divide it by two

Mode

  • arrange the data into ascending order
  • then find the most occurring data

Range

  • The range is the result of subtracting the smallest number from the largest number.

  • To find the range all u need to do is arrange your numbers in ascending order and then subtrack the smalllest number from the largest number

Rayna's Meaurse of Central Tendency

MEAN
  • Arrange it by ascending order.
  • Sum of all data divided by the number of digits in the data




  • Arrange it in ascending order
  • After arranging them whatever is in the middle is the answer
MODE
  • Arrange it by ascending order
  • Whatever number shows up the most times is the mode
  • There can be no mode in a set of data
RANGE
  • Arrange in ascending order
  • subtract smallest number in data set from the biggest number





Jonathan's measures of Tendency


Mean


First you put the data in ascending order then you take a number off the left side and the right side. Keep doing this until there is two or one number left.If there is only one number left that is your mean. If there is two numbers left then you add them up and divide by two to find the median.






Median



To find the mean you have to add up all the numbers and divide by how many numbers there are.



















mode




Finding the mode is simple.All you have to do is find the most common number in the set of data.


















Range


To find the range you have to put the data in asceding order and then subtract the lowest number from the highst number
