Find the median for this set of numbers:
First order the numbers from least to greatest:
Then identify the middle number:
Answer:
Example Question #462 : Data Analysis
Find the median of the set.
The first step towards finding the median of the set is to reorder the numbers from smallest to largest.
The median is equal to middle number in the set. Since this set has an even number of terms, the average of the middle two numbers will be the median.
The middle two numbers are 6 and 6. Find the average.
The median is 6.
Example Question #462 : Data Analysis
What is the median of the set?
The median of a set is the middle number once the numbers are listed from smallest to largest. If we list this set smallest to largest, we get:
Given that 4 is the middle number, it is the median.
Example Question #463 : Data Analysis
What is the median of the set below?
The median is the middle number in a set when ordered smallest to largest.
The set , when ordered smallest to largest is:
When there is an even number of items in a set, the average is taken of the middle two numbers. The middle numbers are 5 and 6. Therefore, the median is the average of these two, which is 5.5.
Example Question #465 : Data Analysis And Probability
The substitute teacher gave her class a quiz. Initially, she believed that there were 15 students in her class who scored an average of 7 out of 10. However, she later realized that there was a 16th student in the class who simply refused to take the quiz, and thereby got a score of 0. What is the average quiz score (to the nearest hundredth), when considering this 16th student?
If 15 students got an average score of 7, and 1 student got a score of 0, the average score of the 16 students can be found with this equation:
Example Question #551 : Ssat Middle Level Quantitative (Math)
In Jane's previous six basketball games, she made the following number of baskets:
What is the median number of baskets she made?
The first step to finding the median is to reorder the number of baskets that Jane scored from smallest to largest. This gives us:
The median number is the number in the middle of the set. Given that there are two middle numbers (4 and 6), the average of these numbers will be the median.
The average of 4 and 6 is:
Example Question #465 : Data Analysis
Find the median in this set of numbers:
The median is the middle number of a data set.
Note: If there are an even number of elements in the set, then the median is the average of the middle two elements. Since this data set has five numbers, we don't have to worry about that, but finding the median of an even set is a common test question!
