### (((Francis Measure of central tendency)))

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

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

- 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

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

- 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

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.

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.

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.

*This is the video for this blog*### Christian's measure of central tendency

**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.

### Katlyn's measure of central Tendacy

**Me**an

### 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.

**- 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.**

### Charissa's Measures of Central Tendency

**Mean**

**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.

**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.

### Gian's Measures of Central Tendency

- Arrange your data in ascending order.

- Sum of all numbers divided by the number of digits in your data and that is your mean.

- Arrange your data in ascending order.
- look for the number in the middle and that your median.

- arrange your set of date in ascending order.
- subtract the largest number and the smallest number together to get the range.

### 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

- 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

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

- 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

- 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

- 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

### 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
