Example Question #33 : Data Analysis And Probability
Consider the data set
.
For what value(s) of would this set have median ?
Any number greater than or equal to
Any number except
Any number greater than
Any number less than
Any number less than or equal to
Any number greater than or equal to
Arrange the eight known values from least to greatest.
For to be the median of the nine elements, it muct be the fifth-greatest, This happens if .
Example Question #31 : Data Analysis And Probability
Consider the data set:
where is not known.
What are the possible values of the median of this set?
The median of this nine-element set is its fifth-highest element. Of the eight known elements, the fourth-highest and fifth-highest elements are both 20. Regardless of the value of , 20 is the fifth-highest element of the nine.
Example Question #35 : Data Analysis And Probability
Examine this stem-and-leaf display for a set of data:
What is the median of this data set?
The "stem" of this data set represents the tens digits of the data values; the "leaves" represent the units digits.
There are 22 elements, so the median is the arithmetic mean of the eleventh- and twelfth-highest elements, which are 64 and 65, the middle two "leaves". Their mean is .
Example Question #32 : Data Analysis And Probability
Determine the median of the following seven test scores:
To determine the median of a set of numbers, you first need to order them from least to greatest:
Since there is an odd number of scores, the median is the score that falls exactly in the middle of the new list. Thus, the median is 88.
Example Question #13 : How To Find Median
Determine the median of the following set of numbers:
To determine the median of a set of numbers, you first need to order them from least to greatest:
Since there is an even amount of numbers, the median is determined by finding the average of the two numbers in the middle - 36 and 44.
Thus, the median is 40.
Example Question #33 : Data Analysis And Probability
Find the median of the following numbers:
The median is the center number when the data points are listed in ascending or descending order. To find the median, reorder the values in numerical order:
In this problem, the middle number, or median, is the third number, which is
Example Question #41 : Data Analysis
What is the median of the following set?
The first step towards solving for the set, is to reorder the numbers from smallest to largest.
This gives us:
The median is equal to middle number in s a set. In since this set has 6 numbers, which is even, the average of the middle two numbers is the mean. The average can be found using the equation below:
Example Question #593 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Find the median of the following data set:
Find the median of the following data set:
Begin by putting your numbers in increasing order:
Next, identify the median by choosing the middle value:
So, our answer is 55
Example Question #11 : How To Find Median
Find the median of the following data set:
Find the median of the following data set:
Let's begin by rearranging our terms from least to greatest:
Now, the median will be the middle term:
Example Question #595 : Isee Upper Level (Grades 9 12) Mathematics Achievement
Find the median of the following data set:
Find the median of the following data set:
First, let's put our terms in increasing order:
Now, we can find our median simply by choosing the middle term.
So, 56 is our median.
