Example Question #21 : Median
Determine the median of the numbers:
Rearrange the numbers from least to greatest.
Since there is an even amount of numbers the median is the average of the central two numbers in the data set.
The answer is:
Example Question #22 : Median
Timothy received the following scores for four math tests:
. In order to get on the honor roll, Timothy must have an average of in his math class. He has one last test coming up. What must he score on the last test in order to make the honor roll?
Recall how to find the average of a set of numbers:
Since we have a total of
tests, we can write the following equation by using the information given by the question:,
where
is the score Timothy must earn on his final test.Now, solve for
.
Example Question #1941 : Ged Math
Determine the median:
Reorder the numbers from least to greatest.
Since there is an odd amount of numbers, the median is the central number for all the numbers of the ordered set.
The answer is:
Example Question #1942 : Ged Math
Determine the median of the numbers:
Rearrange the numbers from least to greatest.
The median is the average of the central two numbers.
The answer is:
Example Question #25 : Median
Find the median of the following data set:
Find the median of the following data set:
To find the median, let's first put our terms in increasing order:
Becomes:
Now, our median is simply the middle term. It is the term which has exactly 50% of the rest of the terms to either side of it.
In this case, it must be 44.
Example Question #122 : Calculations
Find the median of the following data set:
Find the median of the following data set:
Let's begin by putting our numbers in increasing order:
Next, identify the median by finding the middle value.
In this case, it is 44, because 44 is the 6th term in our series, making it the middle value.
Example Question #123 : Calculations
Find the median of the following data set:
Find the median of the following data set:
To find the median, first place your terms in increasing order
Next, ID the median by simply choosing the middle term.
So, our answer is 555
Example Question #1943 : Ged Math
Give the median of the data set:
If the elements of a data set with nine elements - an odd number - are arranged in ascending order, the median of the set is the element that appears in the exact center. The data set, arranged, is
The element in the center is 2, which is the median.
Example Question #125 : Calculations
What is the median for this set of data?
, , , ,
The median is the middle number of a set after it has been ordered from least to greatest. We have
numbers in this set, so our middle number should have numbers on both the left and right side of it in order to be in the middle.is the only number that has numbers on the left and right side of it, so this must be our middle.
Our answer is
.Example Question #131 : Statistics
What is the mean of this set?
, , ,
In order to find the median, we must first make sure our set is ordered from least to greatest, then take the middle number. We can see that it is, as
, the smallest number, is first and , the largest number, is last.Here we can see that we have
numbers in this set, so we don't have a number that sits between an equal amount of numbers on either side. Our two most middle numbers are and .Choosing one will not give us the right answer, so in order to find the median, we must add these two together and divide by
, because that is how many numbers we are adding together.
is our median because it is the number that sits between and .
