The table contains data on the admission price​ (in dollars) for​ one-day tickets to 10 theme parks in the United States. Find the interquartile range for this data set. The numbers are 60 60 42 43 25 52 65 43 42 40

Answer 1

step 1: put the numbers in order form least to greatest
25,40,42,42,43,43,52,60,60,65
step 2: find the median
step 3: place parentheses around the numbers from above and below the median
(25,40,42,42,)43,43,(52,60,60,65)
step 4: find the median from the below parentheses and from the parentheses above
bellow = 41 bc 40 and 42 cant be the median so between those two is 41
above = 60
step 5: subtract below and above medians
60 - 41 = 19
so 19 is your answer
