John is interested in the number of children per household for house-holds in Tyler, TX. He conducts several phone interviews and collects the following data:
| 0 | 3 | 2 | 0 | 2 | 1 | 1 | 0 | 6 | 1 |
Determine if there are any outliers. How do you know?
The observations which are less than 1.5 times the Interquartile range from the first quartile or greater than 1.5 times the Interquartile range from the third quartile, are the outliers.Here,we first need to find out the sorted data set.Here our sorted data set is 0,0,0,1,1,1,2,2,3,6.The total umber of observations are 10.
We first divide the data set into two equal halves and construct two new data sets.We first take the first 5 observations.The median of this data set is the first quartile,Q1. Similarly,we take the next 5 observations,and the median of this data set is our third quartile,Q3.
