What happens if you have two medians?
If there is an odd number of data in the list there is only one number that is exactly in the middle of the data. But if there is an even number of data points then there are two numbers in the middle. In that case you have to add those two numbers together and then divide by two to find the median.
Can we have two medians?
In statistics, the median of a set of data is a central measure that is the number in the data that falls exactly in the middle of the data when the data is listed in order. Because of how the median is defined, it is possible to have two numbers be exactly in the middle of a set of data.
How do I find the median if there are 2 middle numbers?
Example: There are 66 numbers That means that the 33rd and 34th numbers in the sorted list are the two middle numbers. So to find the median: add the 33rd and 34th numbers together and divide by 2.
What is the median in math if there are two numbers?
Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.
How do you solve for median?
To find the median, first order the numbers from smallest to largest. Then find the middle number. For example, the middle for this set of numbers is 5, because 5 is right in the middle: 1, 2, 3, 5, 6, 7, 9….What is the Median?
- {(7 + 1) ÷ 2}th.
- = {(8) ÷ 2}th.
- = {4}th.
Can you take a median of a median?
No, unfortunately there is not a way to calculate the median based on medians of subsets of the whole and still be statistically accurate. If you wanted to calculate the mean, however, you could use the means of subsets, given that they are of equal size.
How do you find the median of two sets of data?
Count how many numbers are in the set. Find the pair of numbers in the middle of the figures. Find the pair's average by adding them together and dividing by two. The resulting number is the median.
What is the median of 4 and 7?
5.5 So, if the dataset has the values, 1, 4, 7, 9, the two center values are 4 and 7. The mean of these middle values is (4 + 7) / 2 = 5.5 , so the median is 5.5.
What is the median of 7?
If there are an odd number of values, the median is simply the middle number. For the dataset 3, 5, 7, 9, 11, the number 7 is the middle number, with two values either side. So the median is 7.
What is median formula in statistics?
If the number of data points is even, the median will be the average of the data point of rank n ÷ 2 and the data point of rank (n ÷ 2) + 1.
How do you find the median of two samples?

What is the median of two arrays?
The median of a sorted array of size n is defined as the middle element when n is odd and the average of the middle two elements when n is even. After merging both arrays, the size of the larger array will be 2n i.e. an even value.
What is the median of 9?
The word "median" literally means the middle of something. In this case, it is the middle number in our data set. The middle number is 9 , therefore this is our median. Hope this helps!
How do you calculate a median?
Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median.
How do we calculate median?
To find the median, calculate the mean by adding together the middle values and dividing them by two.
What is the median of 50?
Where, n is the number of the given number. Hence, the median of first 50 whole numbers is 24.5.
How do you solve for median problems?
End up the calculation by substituting the values in the below formula. Median = l + ( n 2 − c f ) × h. Where 'l' is the lower limit of the median class, 'f' denotes the frequency of the median class, 'h' is the width of the median class, 'c' denotes the cumulative frequency of the class preceding the median class.
Can you take the median of medians?
No, unfortunately there is not a way to calculate the median based on medians of subsets of the whole and still be statistically accurate. If you wanted to calculate the mean, however, you could use the means of subsets, given that they are of equal size.
How do you find the median of two lists?

How do you find the median of two listed lists?
Find the median of the two sorted arrays( The median of the array formed by merging both the arrays). Median: The middle element is found by ordering all elements in sorted order and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).
What are the two formulas of median?
In mean median mode formula the median formula is given for even as well as for odd number of observations (n). If the number of observations is even then the median formula is (Median = ((n/2)th term + ((n/2) + 1)th term)/2) and if n = odd then the median formula is (Median = {(n + 1)/2} th term).
What is the median between two numbers?
The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.
What is the median of 2 numbers?
The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.
How do you find the median of data?
To find the median, first order the numbers from smallest to largest. Then find the middle number. For example, the middle for this set of numbers is 5, because 5 is right in the middle: 1, 2, 3, 5, 6, 7, 9….What is the Median?
- {(7 + 1) ÷ 2}th.
- = {(8) ÷ 2}th.
- = {4}th.
How do you find the median of 8 numbers?
First, arrange the numbers in ascending order. There are 8 numbers in the set — an even number. So, find the average of the middle two numbers, 10 and 24 . So, the median is 17 .
How do you combine two medians?
You need to calculate the median from the combined group, you can't do it from the medians and sizes of the groups….Worksheet Formulas.

How do you work out median?
To find the median, calculate the mean by adding together the middle values and dividing them by two.
What if there are 2 modes?
A set of numbers can have more than one mode (this is known as bimodal if there are two modes) if there are multiple numbers that occur with equal frequency, and more times than the others in the set.
