To find the range, you take the smallest number from the largest.
In this case, the largest number is 111 and the smallest is -3
111 - (-3) = 114
So the range is 114.
111 - 87 = 24
87 is what percent of 75= 87 / 75= 1.16Converting decimal to a percentage: 1.16 * 100 = 116%
Since the set of data is arranged in numerical order, first we need to find the median (also called the second quartile), which separates the data into two equal groups, in our case there are 6 numbers in each group.54 65 66 68 73 75 | 75 78 82 82 87 97The first quartile (also called the lower quartile) is the middle value of numbers that are below the median, in our case is 67.54 65 66 | 68 73 75 | 75 78 82 82 87 97The third quartile (also called the upper quartile) is the middle value of numbers that are above the median, in our case is 82.54 65 66 | 68 73 75 | 75 78 82 | 82 87 97The interquartile range is the difference between the first and third quartiles, which is 15, (82 - 67).

111 - 87 = 24
percentage = 116% % rate: = 87/75 * 100% = 1.16 * 100% = 116%

87 is what percent of 75= 87 / 75= 1.16Converting decimal to a percentage: 1.16 * 100 = 116%
87 + 81 + 80 + 90 + 87 + 75 = 500/6 = 83.3 recurring (that is, 83.3333...)

75% of 116= 75% * 116= 0.75 * 116= 87
87/116 x 100 = 75 percent
Expressed as a percentage, rounded to two decimal places, 75/87 x 100 = 86.21 percent.

Example:Problem:Cheryl took 7 math tests in one marking period. What is the range of her test scores?89, 73, 84, 91, 87, 77, 94Solution:Ordering the test scores from least to greatest, we get:73, 77, 84, 87, 89, 91, 94highest - lowest = 94 - 73 = 21-The range of these test scores is 21 points.so:find the range for each list of scores80,79,85,75,84,76,88,8075,76,79,80,80,84,85,88highest - lowest = range88 - 75 = 13hope this helps :)http://www.mathgoodies.com/lessons/vol8/range.html
