Hello there!
Outlier is a value in a data set that varies significantly from the rest of the data.
Example: Way too low: 1, 45, 58, 60, 63, 75
<u><em>Outlier = 1</em></u>
Way too high: 4, 3, 2, 21, 7
The number should be the order from least to greatest are: 2, 3, 4, 7, 21.
<u><em>Outlier = 21</em></u>
It impact the mean and the median in different ways.
Data with no outlier: 4, 5, 7, 11, 12, 15
54÷6=9
<u><em>Mean = 9</em></u>
Data with an outlier: 4, 5, 7, 11, 12, 15, 58
112÷7=16
<em><u>Mean = 16</u></em>
Median is the middle value in an ordered list of numbers.
Example:
Numbers already in order:
1, 5, 8, 10, 13
Numbers not already in order:
13, 1, 5, 10, 8
1, 5,<u> 8, 10,</u> 13, 15
8+10=18 or 18÷2=9
<u><em>Median =9</em></u>
Range is a difference between the maximum (highest) and minimum (lowest) values. It has one type of measure of spread.
Example:
Data in order: <u>23</u>, 27, 39, 53, 62, <u>84</u>
84-23<u>=61</u>
Data not in order: 272, 52, 67, 201, 43, 256
272-43<u>=229</u>
