It is: 73

It is 73.

Median = middle number = mean of 65 & 66 which is 65.5.

Because there is an even number of numbers, it is the average of the two middle ones. (75 + 79)/2 = 77.

It is 73, the middle value.

71 is the median of those numbers.

80

65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80

Median of the set = arithmetic mean of 75 and 85 = 80

Mean simply means average. To find the average of a set of numbers, simply add them all together and then divide by the amount of numbers you added. 72 + 73 + 74 + 75 + 76 = 370 370 Ã· 5 = 74. The mean of {72, 73, 74, 75, 76} is 74, which is also the median.

The prime numbers between 65 and 75 are: 67, 71 and 73

The numbers are: 72 and 75

Range: 24 Median: 59.5 Mode: 57, 61, 58, 54, 68, 51, 65, 75

Having sorted the list for the median, it can be seen that the one with the highest frequency appears three times: â‡’ mode = 85

The median of the numbers 93 90 90 75 70 68 is 82.5.

56, 57, 64, 65, 66, 75, 76 Mean: 65 and 4/7 Median: 65 Mode: There is no mode. Range: 20

The median is 72.5, which is the number halfway between the two middle numbers when they are arranged in order.

67, 71, 73.

mean = (65 + 56 + 57 + 75 + 76 + 66 + 64)/7 = 65.57 median = "middle" number = 65 mode = most common number = all are equally common

Sort the numbers into numerical order:54, 68, 70, 72, 75, 76, 76, 76, 80, 88, 88, 88, 88, 92, 92, 93The median is the middle number which as there are 16 numbers is the mean of the middle two (highlighted above):median = (76 + 80) Ã· 2 = 78.

Arrange the numbers in ascending order and pick out the middle number but sometimes the two middle numbers need to be added and divided by 2 if there are an even set of numbers. ____________________________________________________ The middle number (in a sorted list of numbers). To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.) Accordingly: The median for: 94 83 78 70 66 68 75 53 54 is: 94, 83, 78, 75, 70, 68, 66, 54, 53 The median is : 70 The median for: 59 83 91 64 65 71 62 86 90 is: 91, 90, 86, 83, 71, 65, 64,, 62, 59 The median is 71

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).

There are 14 numbers - therefore, the median number is halfway between the seventh and eighth number. This is therefore 70.5.

The median is the middle number of a set of numbers when they are arranged in order. If there is an odd amount of numbers, you take the middle number. If there are an even amount of numbers, as in this case, you take the number halfway between the two middle numbers. The two middle numbers are 75 and 80, so halfway between that is 77.5 which is the median.

73 The median is the middle value, so I'll have to rewrite the list in order: 5354596264656668707175787979838386909194 There are 20 numbers in the list, so there is no "middle" number. So, you take the average of the middle two numbers, which is 71 and 75. So the median is 73.
