I don't have a lot of experience at this, but I'll give it a go

 

Arrange the data in order from lowest to highest

 

0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 4, 5, 5, 6

 

find the median  =

find the median  of the data set below  the median  =  2   =  first quartile  value

find the median of the  data set above the median  = 4  =    third quartile  value

 

Find the inter-quartile range (IQR)  = third quartile value - first quartile value  =  4 - 2  = 2

 

To find any possible lower outliers  we find all the values less than

 

first quartile value  - 1.5 (IQR)  =  2 - (1.5)(2)   =  2 - 3   = -1 

There are no values less than -1

 

To  find any possible highest outliers, we find all values greater than

 

third quartile value + 1.5 (IQR)   =  4  + (1.5)(2)  =  4 + 3  = 7  

Tthere are no values greater than 7

 

So.....no outliers exist

 

 

cool cool cool
