Q1=12
Q3=29
so IQR=29-12=17
If the second and third numbers are 2 and 5 and it is not 25 then it is 9.5 and28.5.
Sadly this site still does not support commas in the questions so one cannot tell for sure.
The two easy ways to find interquartile range or IQR are to either use a calculator like the TI 83, or by hand.
By hand you find Q2 which is the median. That divides the data into two halves. Now Q1 is the median of the first half and Q3 is the median of the second half.
Subtract Q1 from Q3 and you have IQR.

(4*10+11+2*12+13+2*14)/10 = 11.6
18 9 11 14 7 9 12 the series is like 18/2= 9 9+2=11 11+3=14 14/2=7 7+2=9 9+3=12 so next number will be.. 12/2=6 then 6+2=8 8+3=11
11
The range is 11. (14 - 3 = 11)
6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16

The average is 12 months. The range is 11 to 14 months.

Mean = 19.8 -----------[(48 + 11 + 15+14+11) / 5]Median = 14 (middle value of the list)Mode = 11 (most frrequent number)Range = 37 (48 - 11, highest - lowest number)
(4*10+11+2*12+13+2*14)/10 = 11.6
12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.
1 is a common factor of 11, 12, 13, 14 and 15.
