Find the interquartile range (IQR) of the data set.

2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2

2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2

(first we find the median)

Median: 5.5

Range: highest value - lowest value

Range: 8.2 - 2.6 = 5.6

Lower quartile: 4.9

Upper quartile: 7.9

Interquartile Range: upper quartile - lower quartile = answer

Interquartile range: 7.9 - 4.9 = 3

Interquartile range (IQR) = 3!

answer: it's d

step-by-step explanation:

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
