### What is the mean median and mode for the following numbers 87 75 89 81 90 73 85 96 65 92 78 79 83 85 79 90 86 72 74 88 81 85?

mean
Add up the numbers and divide by how many there are:
87+75+89+81+90+73+85+96+65+92+78+79+83+85+79+90+86+72+74+88+81+85 =
1813
There are 22 numbers.
⇒ mean = 1813 ÷ 22
= 829/22
≈ 82.41
median
Sort the numbers into order; the median is the middle number (if an
odd number of numbers) or the mean of the middle two (if an even
number of numbers):
Sorted: 65, 72, 73, 74, 75, 78, 79, 79, 81, 81, 83, 85, 85, 85,
86, 87, 88, 89, 90, 90, 92, 96
There are 22, so the median is the mean of the middle two which
are the 11th (83) and 12th (85) numbers:
⇒ median = (83+85) ÷2
= 84
mode
The number which appears the most often. Having sorted the list for
the median, it can be seen that the one with the highest frequency
appears three times:
⇒ mode = 85

### Find the median for 94 83 78 70 66 68 75 53 54 A 59 83 91 64 65 71 62 86 90?

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

###### Asked in Algebra

### What is the interquartile range of 54 and 65 and 66 and 68 and 73 and 75 and 75 and 78 and 82 and 82 and 87 and 97?

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).

###### Asked in Math and Arithmetic

### What is the median of 74 75 80 85 How do you find it?

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.
