Range

Range- The positive difference between the largest and smallest values in a data set.

To find range you must: you take the highest number in the data set minus by the lowest number in the set then it will equal the range.

Outliers - Values that are too big or too small compared to the other values.

10,11,12,12,14,98

98, would be an outlier.

10,11,12,12,14,98

### Range

Eg.

range of 4,8,5,6,9,1,3,5,8,6 is

1,3,4,5,5,6,6,8,8,9

9-1 = 8

### Mean

A measure of central tendency

the sum of a set of values divided by the number of

values in the set

mean of 6,4,8 is

add up all the numbers and divide the results by how many numbers there are

6+4+8=18

18 divide it by 3 = 6

therefor the mean is 6

### Mode

set of data

mode and most both have 4 letters

Eg.

mode of 3,5,7,7,9 is 7

mode of 2,2,4,6,6,8,11 is 2 and 6

### Median

The middle number in a set

of data after the data have been arranged in order

Eg.

median of 2,5,6,8,9 is 6

median of 1,3,6,8,9,10 is 7

of data after the data have been arranged in order

Eg.

median of 2,5,6,8,9 is 6

median of 1,3,6,8,9,10 is 7

### Definition & How to = Outliers

Outliers: Numbers that have small values and numbers that have large values

How to:

ex . 1 , 99 , 99 , 9001 = 1 & 9001

ex . 16 , 4 , 6 , 9 = 16

Multiples can occur, even no mode at all.

ex...

7 , 1 , 9 , 2 , 8 ≠ No Mode

6 , 9 , 0 , 6 , 9 = 69 or 6 & 9

### How to do a circumference question

Hi i'm back again and today I'm going to show you how to to do a circumference question

lets say the question is d=2 m

1 c=d x 3.14 ( 3.14 is pi)

2 c= 2 x 3.14

c=6.28

lets say the question is d=2 m

1 c=d x 3.14 ( 3.14 is pi)

2 c= 2 x 3.14

c=6.28

### How to do two step algebraic equations

here's how you do it lets say the question is 4t-2=10

opposite order of operations

4t-2=10

4t-2+2 = 10 + 2

4t =12

4t/4 = 12/4

t=3

opposite order of operations

4t-2=10

4t-2+2 = 10 + 2

4t =12

4t/4 = 12/4

t=3

### how to add opposite integers

this how to add opposite integers lets say the integers are 5 and (-10so take what you know about zero pares 5 is smaller value wise than (-10) so take negative 5 away for now then add 5 + (-5) = 0 so whats left the (-5) that we left alone while we made a zero pare so that's how to add opposite integers see you latter every body

### What is a zero pare

A zero pare is when two two opposite numbers of the same value are added together to make zero

here is an eg. for you yo look at eg. 8 + (-8)=0 there you that is a zero pare

here is an eg. for you yo look at eg. 8 + (-8)=0 there you that is a zero pare

1,1,2,2,3,3 no mode

3,3,4,4,5,5,6 the mode is 3, 4, and 5

### Outlier

Outlier is a value that is much larger or smaller than the other data value. The data may have more than one outlier or zero outliers. In other words it is the number that doesn't fit in the set.

eg.

2,96,97,98,99

The outlier is 2.

eg.

2,96,97,98,99

The outlier is 2.

### Range

Range is the positive difference between the largest and smallest values in a a data set.

eg.

6,4,2,5,3,1

1,2,3,4,5,6

6-1=5

eg.

6,4,2,5,3,1

1,2,3,4,5,6

6-1=5

### Mean and Median

Mean is a measure of central tendency. It is the sum of a set of values divided by the number of values in a set. In other words add up all the numbers and divide the result by how many numbers there are.

eg.

3,5,7

3+5+7=15

15/3=5

Therefor the mean is 5.

Median is also a measure of central tendency. It is the middle number in a set of data after the data have been arranged in order.

eg.

3,0,1,7,3,2,6

0,1,2,3,3,6,7

The median is 3.

This is how you get the median if you have 2 numbers in the middle:

-Add the 2 numbers and divide the sum by 2.

1,2,3,4,5,6

3+4=7

7/2=3.5

The median is 3.5

eg.

3,5,7

3+5+7=15

15/3=5

Therefor the mean is 5.

Median is also a measure of central tendency. It is the middle number in a set of data after the data have been arranged in order.

eg.

3,0,1,7,3,2,6

0,1,2,3,3,6,7

The median is 3.

This is how you get the median if you have 2 numbers in the middle:

-Add the 2 numbers and divide the sum by 2.

1,2,3,4,5,6

3+4=7

7/2=3.5

The median is 3.5

### Measures of Central Tendency

The Measures of Tendency is a value that represents the centre of a data set that can be the mean, median, or mode.

Data Set is a group of numbers that you must arrange in order from least to greatest.

eg.

6,6,8,3,2,7,5,9,0,4,6,7,8,3,2

0,2,2,3,3,4,5,6,6,6,7,7,8,8,9

Data Set is a group of numbers that you must arrange in order from least to greatest.

eg.

6,6,8,3,2,7,5,9,0,4,6,7,8,3,2

0,2,2,3,3,4,5,6,6,6,7,7,8,8,9

## Monday, June 4, 2012

### Outlier

The data set may have more then 1 outlier or zero outliers

Eg. Outliers for 1, 67, 68, 67, 64, 65, 100 are 1 and 100

### Mean

The sum of a set of values divided by the number of values

Eg. The mean of 6, 4, 8 is 6

Add up all the numbers then divide by how many numbers are in the data set

Eg. The mean of 6, 4, 8 is 6

Add up all the numbers then divide by how many numbers are in the data set

### Mode

The most frequently occurring number in a set of data

Eg. The mode of 3, 5, 5, 6, 7 is 5 because there are 2 5's

Eg. The mode of 3, 5, 5, 6, 7 is 5 because there are 2 5's

### Median

The middle number of a set of data after the numbers are arranged in order

__Eg. 1, 2, 2, 3, 4, 5, 6, 7, 8__The middle number is 3

### Range

Range

Eg. Range of 1, 7, 7, 8, 8, 9

The positive difference between the largest and smallest values in a data set

Eg. Range of 1, 7, 7, 8, 8, 9

__9 - 1 = 8__## Sunday, June 3, 2012

### Range

**Positive difference between largest and smallest values in a data set.**

ex: 1,3,4,5,5,6,6,8,8,9

9-1=8

### Measures of Central Tendency

**A value that represents center of a data set.**

**Can be Mean, Median or Mode.**

## Friday, June 1, 2012

### outliers

A value that "lies outside" (is much smaller or larger than) most of the other values in a set of data.

### range

The difference between the lowest and highest values.

In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9-3 = 6.

In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9-3 = 6.

### median

- The median is the middle value, so I'll have to rewrite the list in order:

- 13, 13, 13, 13, 14, 14, 16, 18, 21

- 13, 13, 13, 13, 14, 14, 16, 18, 21
