Median is average so 80.
The median is 86.
To find the mean, add the numbers (84 + 85 + 88 + 89 + 82 + 78 + 82) to get 508, then divide by 7, resulting in a mean of approximately 72.57. The median is the middle value when the numbers are arranged in order (78, 82, 82, 84, 85, 88, 89), which is 84. The mode is the number that appears most frequently, which is 82. The range is the difference between the highest (89) and lowest (78) values, giving a range of 11.
83
The median is 85.
The median and mode are both 82. The mean is 84.6
78
The median is 86.

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).
78
85
It is 81.5, the number halfway between the two middle numbers.
69 + 78 + 82 = 229
To find the median of a set of numbers, you first need to arrange them in numerical order. Once you have them in order, the median is the middle number. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers. In this case, the numbers arranged in numerical order are: 78, 81, 82, 88, 88, 88, 89, 91, 91, 92, 93, 94, 95, 96, 98. Since there are 15 numbers, the median will be the 8th number, which is 89.
