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 97
The 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 97
The 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 97
The interquartile range is the difference between the first and third quartiles, which is 15, (82 - 67).
66 is greater than 54.
It is 54/66 which can be simplified, if required.
The greatest common factor 54 and 66 is 23.
-20
The LCM is 9504.
3, 3, 3, 9, 9, 11, 12, 14, 15, 15, 23 Median is 11 Mode is 3 Range is 20
56, 57, 64, 65, 66, 75, 76 Mean: 65 and 4/7 Median: 65 Mode: There is no mode. Range: 20
66 is greater than 54.
It is 54/66 which can be simplified, if required.
mean is (54+66)/2 = 60
The lowest common multiple of 54 and 66 is 594.
The greatest common factor 54 and 66 is 23.
-20
120-54 = 66
81.8% 54/66 * 100= % right
The LCM is 9504.
The LCM is 2376.
