Arean Asgariani GE 219 5. The mode is $1,000 to $2,999. The median is $10,000 to $12,499. The formula for the interquartile range is Q3-Q1. First find the value of Q1: One way to locate the value at the first quartile is by locating the value associated with the 25 th percentile, value 3 ($3,000 to $3,999). You can also locate the case at Q, with the following formula (N+1)(.25)=(119+1)(.25)=(120)(.25)=30. Then locate the value at Q, that is associated with case 30, value 3 ($3,000 to $3,999). Next locate the value at Q3 using the 75 th percentile. The value at the 75 th percentile is value 14, $22,500 to $24,999. You can also locate the case at Q3 with the following formula (N+1)(.75)=(119+1)(.75)=(120)(.75)=90. Then locate the value at Q3 that is associated with case 90, value 14 ($22,500 to $24,999). Find the interquartile range: Q3 – Q1= 14-3= 11. In relation to the range (20 – 1 =19), the distribution is somewhat heterogeneous. Half of the respondents ages 18-25 earn from $3,000 to $24,999 a year. One quarter earn $3,999 a year or less, and one quarter earn
